After Halitosis Treatment: Hydration, Tongue Cleaning and the Daily Routine Dentists Recommend

The hygienist’s chair tilts back up, the paper bib comes off, and for a few hours your mouth feels like a freshly mopped floor. Then comes the quieter question on the drive home: how do I keep it this way? Most people who have been treated for bad breath, whether that meant a deep cleaning, gum therapy, a repaired filling or help for a dry mouth, discover that the appointment was the easy part.

A halitosis daily routine is where the result either holds or slowly slips. The bacteria that produce the odor do not disappear after treatment; they are part of every healthy mouth. What changes is how much food, dead cells and dryness you give them to work with, hour by hour.

This explainer walks through what dentists actually ask patients to do once treatment is finished, why hydration and tongue cleaning get so much attention, and which popular fixes have little evidence behind them.

What is halitosis, and where does the smell actually come from?

Halitosis is the clinical word for persistent bad breath, odor that is noticeable to others and does not clear after brushing or a glass of water. Almost everyone has a stale mouth on waking; halitosis is the version that lingers into the afternoon.

The chemistry is unglamorous. Bacteria that thrive without oxygen settle into the grooves of the tongue, the pockets between gum and tooth, and any spot where food debris sits undisturbed. As they break down proteins from food, saliva and shed cells, they release gases called volatile sulfur compounds. Hydrogen sulfide smells like rotten eggs; methyl mercaptan smells like cabbage left too long in a pot. Those two account for most of what another person actually detects.

According to the Cleveland Clinic, the back of the tongue is the single largest reservoir, because its rough surface traps debris and rarely gets touched by a toothbrush. The NHS lists the usual drivers in order of frequency: poor oral hygiene, gum disease, a dry mouth, smoking, and strongly flavored foods such as garlic and onion. Less often, the source sits outside the mouth: tonsil stones, sinus drainage trickling down the throat, acid reflux, or a medical condition such as poorly controlled diabetes, which can give breath a fruity, acetone-like note.

That ordering matters for everything that follows. If roughly nine out of ten cases begin in the mouth, as the Mayo Clinic notes, then the mouth is where a daily routine does its heaviest lifting. Treating the gum disease or filling the cavity removes the bacterial headquarters. The routine stops a new one from forming.

What does halitosis treatment usually involve?

There is no single procedure called halitosis treatment. What a dentist does depends on what the examination finds, and most of the work is ordinary dentistry aimed at a specific cause.

For gum disease, the most common starting point is a professional cleaning called scaling and root planing: hardened plaque (tartar) is scraped from the teeth and from the root surfaces below the gumline, so the pockets where bacteria hide can shrink. For a cracked filling or a cavity trapping food, the tooth is repaired. For a coated tongue, the hygienist demonstrates tongue cleaning and often checks technique at the next visit. For dry mouth, the dentist may review the medicines that reduce saliva with the prescribing clinician, or suggest saliva substitutes; any change to medication stays with the prescriber.

When the mouth looks healthy and the odor persists, the Mayo Clinic describes a different path: referral to a physician to look at the sinuses, throat, stomach or metabolic causes. That handoff is a normal part of care, not a sign that something was missed.

In every version, the appointment resets the mouth to a lower bacterial load. The NHS is explicit that the fix then depends on daily habits: brushing, cleaning between teeth and tongue care. The treatment opens a window; the routine keeps it open.

Patients often ask whether a prescription antibacterial mouth rinse will be part of the plan. Sometimes it is, for a defined period after gum therapy, with the dentist explaining why and for how long. It is an adjunct to mechanical cleaning, never a replacement for it, and its use is the clinician’s call.

Who needs a halitosis daily routine, and who is asked to wait?

Strictly speaking, everyone with teeth benefits from the same core habits. The daily routine for someone recovering from halitosis treatment is not an exotic protocol; it is standard oral hygiene done with more consistency and one added step, the tongue.

The people who gain most are those whose odor came from a modifiable source: gum inflammation, a heavy tongue coating, mouth breathing, or dryness from medicines. For them the routine is the treatment’s second half. People who smoke, who take several medicines that dry the mouth, or who wear dentures or orthodontic appliances tend to need the routine to be stricter, because each of those factors gives bacteria extra shelter or less saliva to contend with.

There are moments when a dentist asks you to pause part of the routine or modify it:

• After an extraction or gum surgery, vigorous rinsing and brushing near the site are usually held back for a short period set by the surgeon, to protect the blood clot and healing tissue.
• With a mouth ulcer, cut or burn on the tongue, tongue scraping is normally paused until it heals; the NHS advises seeing a dentist or doctor if an ulcer lasts more than three weeks.
• During cancer treatment affecting the mouth, the oncology and dental teams set the hygiene plan together, often favoring very soft brushes and alcohol-free rinses.
• Young children should have tongue cleaning and interdental cleaning introduced by a dentist, not copied from an adult routine.

None of these pauses mean giving up on fresh breath. They mean the routine is adapted to tissue that needs protecting first. When in doubt about timing after a procedure, the surgeon’s written instructions take precedence over any general advice, including this article.

Dry mouth and bad breath: why hydration ranks above mouthwash

Saliva is the mouth’s unpaid cleaner. It rinses debris off the tongue and teeth, dilutes sulfur gases, buffers acids and carries antibacterial proteins. When it runs low, odor rises within hours. That is why morning breath is universal: the Mayo Clinic notes that saliva production drops sharply during sleep, letting bacteria work undisturbed overnight.

Dry mouth (xerostomia) is the persistent daytime version. The NIH’s National Institute of Dental and Craniofacial Research lists its common causes: many prescription and over-the-counter medicines, including some for blood pressure, allergies, depression and pain; dehydration; mouth breathing; and conditions such as diabetes or Sjögren’s syndrome. Chemotherapy and radiation to the head and neck can reduce saliva as well.

Hydration is the simplest lever. Sipping plain water through the day keeps the tongue surface moist and physically moves debris toward the throat to be swallowed. It does not need to be heroic volumes; frequent small sips help more than one large bottle at lunch, because the goal is a mouth that never stays dry for long. Chewing sugar-free gum or sucking sugar-free lozenges after meals stimulates saliva flow, a step the Mayo Clinic and NHS both list. Breathing through the nose where possible, and running a humidifier in a dry bedroom, address the overnight dip.

Caffeine and alcohol pull in the opposite direction. Both reduce saliva, and alcohol-containing mouthwash can leave the mouth drier than before, which is why many dentists steer patients with dry mouth toward alcohol-free formulas.

If dryness is severe or constant, that is a medical conversation, not a hydration problem. The prescribing clinician may be able to adjust timing or choice of medicines; the patient should not do so alone.

How to clean your tongue without gagging or scraping too hard

Look at your tongue in a mirror after breakfast. The front is pink; toward the back, a pale film sits in the grooves. That film is a mat of bacteria, food residue and dead cells, and the Cleveland Clinic identifies it as the main source of oral odor in people whose teeth and gums are otherwise healthy.

Tongue cleaning removes the mat mechanically. The technique dentists teach is modest:

• Use a dedicated tongue scraper or the back of a soft toothbrush. Scrapers, flat strips of plastic or metal, cover more surface with less bulk in the mouth, which is why many people find them less likely to trigger gagging.
• Stick the tongue out, place the tool as far back as is comfortable, and draw it forward in one light stroke. Rinse the tool. Repeat three or four times, moving slightly to each side.
• Pressure should be gentle enough that the tongue never feels sore or looks raw afterward. The aim is to lift the coating, not to polish the muscle.
• Finish by rinsing the mouth with water and cleaning the scraper.

Once a day is the usual recommendation, typically in the morning when the overnight coating is thickest. People who gag easily can start closer to the middle of the tongue and work backward over a few weeks, exhaling slowly during the stroke; the reflex tends to settle with practice.

Two cautions. A tongue that is persistently white, patchy, red, or painful is a reason to see a dentist rather than to scrape harder, since those changes can signal thrush, irritation or other conditions. And a scraper is a complement to brushing and flossing, never a substitute; a clean tongue above inflamed gums will not stay fresh for long.

The halitosis daily routine dentists recommend, morning to night

Written out, the routine looks longer than it feels. In practice it adds perhaps two minutes to what most people already do, and each step maps onto a known source of odor.

Time	Step	Why it matters
Morning	Brush two minutes with fluoride toothpaste; spit, don’t rinse	Removes overnight plaque; leaving fluoride on teeth protects enamel (NHS)
Morning	Clean the tongue, back to front, a few light strokes	Lifts the coating that holds most odor-producing bacteria (Cleveland Clinic)
Through the day	Sip water; chew sugar-free gum after meals	Keeps saliva flowing, dilutes sulfur gases (Mayo Clinic)
After meals	Rinse with water; brush later if food was acidic	Clears debris; NHS advises not brushing straight after acidic food
Evening	Clean between teeth with floss or interdental brushes	Reaches the gum pockets a brush misses (NHS)
Evening	Brush two minutes; clean dentures or retainers as instructed	Last clean before the overnight saliva drop

Three details carry most of the weight. First, the two-minute, twice-daily brushing figure comes from the NHS and is not arbitrary; shorter sessions leave plaque behind at the gumline, where gas production is highest. Second, cleaning between teeth once a day is the step people skip, yet gum disease begins exactly there. Third, the evening clean is the more important of the two, because whatever is left sits for seven or eight hours in a dry mouth.

The Mayo Clinic adds a housekeeping point: replace the toothbrush, or electric brush head, roughly every three months or sooner once bristles fray. Bent bristles clean poorly and can scratch gums.

Dental review intervals are set individually. The NHS describes a range from every three months for people with active gum disease to every two years for those with very healthy mouths; after halitosis treatment, early visits are often closer together so the hygienist can check tongue technique and gum healing.

What is the 3-3-3 rule for dental care, and is it evidence-based?

Search for brushing advice and a tidy slogan appears: the 3-3-3 rule. Brush three times a day, for three minutes, within three minutes of eating. It is memorable, and it comes up often enough in patient questions that it deserves a straight answer.

The rule is not from any national guideline. It appears to have spread as a classroom mnemonic. Compared with what the NHS and the Mayo Clinic actually recommend, it overshoots on frequency and duration and gets the timing partly wrong.

Frequency: twice a day, morning and last thing at night, is the standard. A third brush is not harmful if done gently, but it adds little once plaque is being removed thoroughly twice daily, and heavy-handed extra sessions can wear gum tissue over years.

Duration: two minutes is the referenced figure. Three is fine if that is how long a thorough job takes; the point is coverage of every surface, not the clock.

Timing is where the slogan misleads. The NHS specifically advises not brushing immediately after eating, especially after acidic foods and drinks such as fruit, soda or wine, because acid temporarily softens enamel and brushing then scrubs it away. Waiting about an hour, or rinsing with water in the meantime, protects the teeth. For fresh breath after lunch, water, a sugar-free gum and a tongue check in the restroom mirror do the job without the enamel cost.

What the 3-3-3 rule gets right is the underlying instinct: breath depends on consistency, not on a single heroic clean. If a rhyme helps someone remember to brush at night, it has done useful work. Just swap in the referenced numbers: two times, two minutes, and a pause after acidic meals.

Mouthwash, gum and mints: what they do, and what they cannot do

The breath-care aisle is built on a quiet confusion between masking odor and reducing it. Both have a place; only one changes the chemistry.

Mints and flavored sprays mask. They overlay sulfur gases with menthol or citrus for a short while and do nothing to the bacteria producing them. Sugared versions feed those bacteria, which is why the NHS and Mayo Clinic specify sugar-free when they recommend gum or sweets at all. Sugar-free gum earns its place through a different route: chewing pulls saliva into the mouth, and saliva is the real cleanser.

Mouthwash sits in the middle. A cosmetic rinse masks. An antibacterial rinse, the kind containing agents such as cetylpyridinium chloride or chlorhexidine, temporarily lowers the bacterial count and the gases they produce. The Mayo Clinic lists antibacterial rinses among reasonable measures, but with two caveats worth repeating. Rinsing does not remove plaque; only bristles and floss do that, so mouthwash on top of poor brushing is perfume on an unmade bed. And chlorhexidine, which is prescription-strength in many places, is typically used for limited periods under a dentist’s direction because longer use stains teeth and alters taste. Whether it belongs in your plan, and for how long, is the clinician’s decision.

Alcohol content deserves attention for anyone with a dry mouth. Alcohol evaporates quickly and can leave tissues drier, which over a day can worsen the very odor the rinse was meant to fix. Alcohol-free formulations avoid that trade-off.

So the honest ranking runs: brush and floss first, tongue cleaning second, water and sugar-free gum through the day, and a rinse as an optional finish chosen with the dentist. Nothing in a bottle should move up that list.

Food, coffee, alcohol and smoking: the everyday odor sources

Some breath odor has nothing to do with hygiene. Garlic and onion contain sulfur compounds that are absorbed into the bloodstream, carried to the lungs and exhaled; the smell persists until the body has processed them, which is why brushing after a garlic-heavy meal helps the mouth but not the breath. The NHS lists these foods among common causes and the fix is simply time, or avoiding them before occasions that matter.

Coffee contributes in two ways. Its compounds have their own lingering aroma, and caffeine reduces saliva, leaving a drier mouth for bacteria. A glass of water alongside each cup offsets some of the effect. Alcohol does the same drying work, and evening drinks compound the overnight saliva dip, which many people notice as a particularly stale morning.

Smoking and vaping deserve their own paragraph. Tobacco leaves a direct odor, dries the mouth, stains the tongue coating and, most consequentially, is a leading risk factor for gum disease, the second most common cause of halitosis in the NHS list. Stopping smoking is the single lifestyle change with the largest effect on breath over months, and support for quitting is available through primary care. Vaping products also dry the mouth and their long-term effect on gum health is still being studied.

Low-carbohydrate and fasting diets can produce a sweet, acetone-like breath as the body burns fat and releases ketones. It is a normal metabolic by-product in healthy people on those diets, but the same smell in someone with diabetes, especially alongside thirst and frequent urination, needs prompt medical assessment, as the Mayo Clinic notes.

Finally, long gaps between meals matter. Saliva flows with chewing; a skipped lunch means a quieter, drier mouth all afternoon. Crunchy fruit and vegetables stimulate flow and mechanically wipe the tongue as they pass.

Bad breath after dental cleaning: what the first days and weeks usually look like

The arc after treatment is more gradual than people expect, and it helps to know the shape of it in advance.

The first day or two after a deep cleaning, gums can feel tender and may bleed slightly when brushed. Some people notice an odd taste or a faint metallic odor as tiny amounts of blood and disturbed tartar clear. That is normal, and the right response is to keep brushing gently rather than to avoid the sore areas; skipped spots refill with plaque within a day. If the dentist prescribed a short course of antibacterial rinse, use it as instructed and for the stated period only.

Over the first week, bleeding on brushing typically eases as inflammation settles. This is the window in which the tongue-cleaning habit either sticks or lapses; pairing it with an existing cue, such as the morning brush, is the most reliable way to keep it.

Over two to six weeks, gum tissue tightens around the teeth and pockets shallow, which removes shelter for anaerobic bacteria. Many people report that the afternoon staleness fades in this period. The dentist’s review visit, often scheduled within this range, checks pocket depths and technique.

Judging progress is tricky because people cannot smell their own breath; the nose adapts. A trusted partner’s honest opinion, or the dentist’s assessment at review, is more reliable than licking a wrist. Some practices use a halimeter, a device that measures sulfur gases, but it is a research and monitoring tool rather than a necessity.

If odor is unchanged after six to eight weeks of consistent routine, that is not a failure of effort. It is information, and the Mayo Clinic’s advice at that point is a return visit, with referral to a physician if the mouth looks healthy.

Bad breath home remedies: cloves, vitamins, oil pulling and what the evidence shows

Two of the most-searched questions about breath concern cloves and vitamin deficiency. Both deserve a measured answer rather than a dismissal.

Is chewing cloves good for fresh breath? Cloves contain eugenol, an aromatic compound with antibacterial activity in laboratory studies, and their strong scent masks odor for a while. There are no robust clinical trials showing that chewing cloves treats halitosis, and whole cloves are fibrous enough to irritate the gums or tongue if chewed often. As a flavor they are harmless for most people; as a treatment they are unproven. Eugenol in concentrated oil form can burn oral tissue and should not be applied directly.

What vitamin are you lacking if you have bad breath? Usually none. Halitosis is a bacterial and hygiene story far more often than a nutritional one. The one real link is vitamin C: severe deficiency weakens gum tissue and causes bleeding, swollen gums, which can smell. That degree of deficiency is uncommon in people eating a mixed diet, and taking supplements without a deficiency does not freshen breath. If gums bleed and bruising or fatigue accompany it, a doctor can check with a blood test; self-prescribing vitamins is not the answer.

Oil pulling, swishing edible oil for many minutes, has a few small studies suggesting a modest reduction in bacteria, but none of sufficient quality to recommend it over brushing, and it adds nothing a brush and scraper do not already do.

Baking soda rinses and green tea have weak supporting data and are low risk. Apple cider vinegar is acidic and erodes enamel; dentists generally advise against it.

The pattern across all of these is consistent: anything that mechanically removes debris or stimulates saliva has a plausible mechanism; anything that merely smells strong is masking. Home measures are fine alongside the routine, never instead of a dental assessment.

What people often get wrong about keeping breath fresh

The myths around bad breath are stubborn because several of them feel logical. Here are the ones dentists correct most often.

Harder brushing cleans better. It does not. Pressure wears gums back and exposes root surfaces, which are rougher and trap more debris. Light pressure with a soft brush, covering every surface for two minutes, removes more plaque than a hard scrub.

Mouthwash can replace flossing. Liquid cannot lift the sticky biofilm wedged between teeth. The NHS places interdental cleaning alongside brushing as a daily essential, not an optional extra.

Rinsing after brushing is necessary. The NHS advice is to spit out excess toothpaste and not rinse with water, so the fluoride stays on the teeth longer. Many people were taught the opposite as children.

Bad breath means something is wrong with the stomach. Reflux can contribute in some people, but the Mayo Clinic notes the great majority of cases begin in the mouth. Treating a healthy stomach will not fix a coated tongue.

You can tell by cupping your hands. The nose adapts to its own environment within minutes. Breath from the lungs through cupped hands does not represent what others smell from a conversation distance.

A clean mouth should taste minty. Flavor is not cleanliness. A mouth can be mint-fresh and still carry a heavy coating at the back of the tongue, or taste of nothing and be thoroughly clean.

Once treated, it is done. This is the one that costs people their result. The bacteria return daily; the routine is permanent, and the appointment was a reset, not a conclusion.

Questions to ask your care team before you leave the chair

The ten minutes at the end of an appointment are the best chance to tailor a generic routine to your mouth. Patients who leave with specific answers tend to keep the habit; those who leave with a leaflet often do not. Questions worth bringing:

• What did you find as the main source of my odor, and has it been fully treated or will it need more visits?
• Should I use a tongue scraper or the brush, and can you show me how far back to go?
• Which spots between my teeth need extra attention, and is floss or an interdental brush better for them?
• Do you want me to use a mouth rinse, which type, and for how long? Should I stop it at some point?
• Are any of my medicines likely to be drying my mouth, and is that worth raising with the prescriber?
• How soon do you want to see me again, and what will you check then?
• If the odor has not improved by that visit, what is the next step?
• Are there signs I should watch for that mean I should call sooner?
• Should my partner or family tell me honestly how my breath is, and when would that feedback be most useful?
• Is there anything about my dentures, retainer or braces that needs a different cleaning routine?

Write the answers down. Dental advice tends to arrive while a mirror is in your mouth, and even careful listeners lose half of it by the parking lot. If a question only occurs to you later, most practices are happy to answer by phone; that is better than guessing.

When to call your doctor or dentist

Most persistent bad breath is a dental matter and resolves with treatment and the daily routine described here. Some patterns, though, point beyond the mouth or signal a problem that needs prompt attention. Contact your dentist or doctor if you notice any of the following:

• Odor that persists after six to eight weeks of consistent brushing, interdental cleaning and tongue care, especially if the dentist has already found the mouth to be healthy.
• Gums that bleed heavily, are swollen or painful, or teeth that feel loose or have shifted.
• A mouth ulcer, white or red patch, or lump that has not healed within three weeks, which the NHS advises should always be examined.
• A sweet, fruity or acetone-like smell on the breath together with unusual thirst, frequent urination, nausea or tiredness; this can indicate uncontrolled diabetes and needs same-day medical assessment.
• An ammonia-like or fishy breath odor, or breath changes alongside swelling of the legs, jaundice or unexplained weight loss.
• Severe or constant dry mouth, particularly with dry eyes or difficulty swallowing food.
• Fever, a very sore throat, white deposits on the tonsils, or pain when swallowing, which can indicate infection.
• Bad breath in a young child that persists despite good cleaning, which can occasionally mean a foreign object in the nose or a sinus problem.

Seek urgent care if breath changes come with confusion, rapid breathing, severe abdominal pain or vomiting, since these can accompany metabolic emergencies.

None of these signs confirm a diagnosis; they are reasons to be examined. The treating team decides what tests, referrals or changes to medicines are appropriate, and that decision should rest with them rather than with a search engine or this article.

Frequently asked questions

What is halitosis?

Halitosis is persistent bad breath that others can notice and that does not clear with brushing or a drink of water. It is produced mainly by bacteria on the tongue and around the gums releasing volatile sulfur compounds. The NHS lists poor oral hygiene, gum disease, dry mouth, smoking and strong-smelling foods as the usual causes, with sinus, throat, digestive or metabolic conditions responsible in a smaller share of cases.

What is the 3-3-3 rule for dental care?

The 3-3-3 rule is an informal slogan: brush three times a day, for three minutes, within three minutes of eating. It is not part of any national guideline. The referenced standard from the NHS is twice a day for two minutes with fluoride toothpaste, and the NHS specifically advises against brushing straight after acidic food or drink because softened enamel wears away. Rinsing with water and waiting is the safer approach.

Is chewing cloves good for fresh breath?

Cloves mask odor temporarily and contain eugenol, which shows antibacterial activity in laboratory studies, but there are no good clinical trials showing cloves treat halitosis. Whole cloves can irritate gums if chewed frequently, and concentrated clove oil can burn oral tissue. As an occasional flavor they are harmless for most people; they are not a substitute for brushing, interdental cleaning and tongue care.

What vitamin are you lacking if you have bad breath?

Usually none. Bad breath is almost always a bacterial and hygiene problem rather than a nutritional one. The only well-established link is severe vitamin C deficiency, which weakens gum tissue and causes bleeding, swollen gums that can smell; this is uncommon in people eating a varied diet. Supplements do not freshen breath in people who are not deficient. If gums bleed alongside fatigue or easy bruising, a doctor can test for deficiency.

How do you clean your tongue properly?

Use a tongue scraper or the back of a soft toothbrush, place it as far back as is comfortable, and draw it forward in one light stroke; rinse the tool and repeat three or four times across the surface. Pressure should never leave the tongue sore. Once a day, usually in the morning, is typical. People who gag can start further forward and move back gradually over a few weeks.

Why do I have bad breath after dental cleaning?

A faint metallic taste or odor in the first day or two after a deep cleaning is common, as small amounts of blood and disturbed tartar clear and gums settle. It usually fades within days as inflammation reduces. Keep brushing gently rather than avoiding tender areas, since skipped spots refill with plaque quickly. If odor, pain or bleeding worsens or persists beyond a week, contact the dental practice.

Does dry mouth cause bad breath?

Yes. Saliva rinses debris, dilutes sulfur gases and carries antibacterial proteins, so when it runs low, odor rises within hours. The NIH lists medicines, dehydration, mouth breathing, diabetes and Sjögren’s syndrome among common causes of dry mouth. Sipping water through the day, chewing sugar-free gum and choosing alcohol-free mouth rinses help; persistent severe dryness should be discussed with a doctor, who may review medicines.

What causes morning breath?

Saliva production drops sharply during sleep, according to the Mayo Clinic, so bacteria on the tongue and gums work undisturbed overnight and their sulfur gases build up. Mouth breathing, snoring, alcohol in the evening and a skipped bedtime clean all make it stronger. Morning breath that clears after brushing and water is normal; odor that lingers through the day is the pattern worth raising with a dentist.

Should I use mouthwash with alcohol for bad breath?

For most people with a dry mouth, alcohol-free is the better choice, because alcohol evaporates quickly and can leave tissues drier, which worsens odor later in the day. Antibacterial rinses can temporarily lower bacterial counts, but no rinse removes plaque; brushing and interdental cleaning do that. Whether a prescription-strength rinse belongs in your routine, and for how long, is a decision for your dentist.

How long after halitosis treatment should breath improve?

There is no fixed timeline, because it depends on the cause. After gum treatment, bleeding usually eases within the first week and gum tissue tightens over the following weeks, with many people noticing less afternoon staleness in that period. If odor is unchanged after six to eight weeks of consistent routine, the Mayo Clinic advises returning to the dentist, who may refer on if the mouth looks healthy.
