Toothache plant is a flowering herb traditionally used to create a tingling or numbing sensation in the mouth. Although it may briefly reduce awareness of minor oral discomfort, it cannot diagnose or treat cavities, infection, gum disease, cracks, or other causes of tooth pain.

What Is Toothache Plant?

Toothache plant is the common name most often used for Acmella oleracea, an edible flowering plant in the daisy family. It is also sometimes called electric daisy, paracress, buzz button, or, in older sources, Spilanthes acmella. The leaves and flower heads have been used in traditional food and herbal practices in parts of South America, Africa, and Asia.

When chewed, the plant can produce a strong tingling, warming, or temporarily numbing feeling on the tongue, lips, gums, and inside of the mouth. It may also increase saliva production. These effects explain its traditional association with toothache, but a sensation of numbness is not the same as treating the underlying dental problem.

The main bioactive compound linked to this effect is spilanthol, an alkylamide found in the plant. Toothache plant is sold in several forms, including fresh leaves or flowers, dried herb, teas, tinctures, extracts, lozenges, and oral-care products. The amount of active compound can differ greatly between products, so effects and safety may not be predictable.

What Does the Research Say About Toothache Plant?

What Does the Research Say About Toothache Plant? — toothache plant

Laboratory and early research suggests that spilanthol and related plant compounds may have local sensory effects and may influence inflammation or microorganisms under experimental conditions. However, laboratory findings do not establish that a product is effective for treating a painful tooth, gum infection, or oral disease in people.

High-quality clinical studies specifically evaluating toothache plant for tooth pain are limited. There is not enough reliable evidence to show that chewing the plant, using a rinse, or taking an extract safely relieves dental pain better than established dental care. There is also no good evidence that it can cure a cavity, reverse tooth decay, drain an abscess, repair a cracked tooth, or treat periodontal disease.

Dental pain is often a warning signal rather than a condition that should simply be suppressed. A temporary tingling or numbing effect may make symptoms less noticeable while decay or infection continues. For this reason, toothache plant should be viewed, at most, as a traditional comfort measure rather than a replacement for an examination by a dentist.

Why Toothaches Need a Cause-Based Approach

Why Toothaches Need a Cause-Based Approach — toothache plant

Toothache is not a diagnosis. It can result from tooth decay, exposed tooth roots, gum inflammation, a cracked tooth, an old filling that no longer seals properly, teeth grinding, an erupting wisdom tooth, or an infection in the tooth or surrounding tissues. Some pain that feels as though it comes from a tooth can also be related to the sinuses, jaw joint, or nearby nerves.

A dentist typically identifies the cause by asking about symptoms, examining the teeth and gums, testing the tooth when appropriate, and sometimes taking dental X-rays. Treatment depends on the finding. It may involve improving oral hygiene, placing or replacing a filling, treating gum disease, protecting a damaged tooth, performing root canal treatment, or removing a tooth when it cannot be saved.

In particular, a dental abscess requires professional care. Antibiotics are not routinely needed for every toothache, and they do not remove the source of pain when dental treatment is necessary. Prompt assessment helps prevent complications and supports the most conservative effective treatment whenever possible.

  • Short, sharp pain with cold or sweet foods may occur with decay, sensitivity, or a crack.
  • Lingering pain after hot or cold foods may suggest inflammation inside the tooth.
  • Pain on biting can occur with a crack, loose restoration, or inflammation around the tooth root.
  • Throbbing pain, swelling, bad taste, or fever may indicate an infection requiring urgent assessment.

Potential Risks and Who Should Be Cautious

Natural products can cause side effects and allergic reactions. Because toothache plant belongs to the Asteraceae family, people who are allergic to ragweed, chamomile, chrysanthemums, marigolds, echinacea, or other daisies may be more likely to react to it. Possible reactions include mouth irritation, itching, rash, swelling, or breathing symptoms. Anyone with signs of a serious allergic reaction should seek emergency care.

The strong tingling and saliva-producing effects can be unpleasant, particularly in concentrated extracts. A numbed mouth may also make it easier to accidentally bite the cheek, tongue, or lip. Products applied directly to irritated gums or open mouth sores may sting and could worsen local irritation.

There is insufficient reliable safety information about medicinal use of toothache plant during pregnancy or breastfeeding. Children, people with chronic medical conditions, and those taking regular medicines should consult a doctor, pharmacist, or dentist before using herbal extracts. Potential interactions have not been well studied, and supplement labels do not always accurately reflect ingredients or strength.

It is also important to avoid placing crushed aspirin or other medicines directly on a painful tooth or gum. This does not treat the cause and can burn oral tissue. Pain relief medicines should only be used as directed on the label or by a clinician, taking account of personal health conditions and other medications.

Safer Self-Care While Waiting for a Dental Visit

For mild tooth discomfort while arranging dental care, simple measures may help reduce irritation. Gently brushing twice daily with fluoride toothpaste and cleaning between teeth can remove trapped food and plaque. Rinsing the mouth with warm salt water may be soothing for some people, especially if the gums feel tender. A cold compress held against the outside of the cheek may help with pain or mild swelling.

Until the tooth is assessed, it may help to avoid very hot, cold, sweet, or acidic foods if they trigger pain. Chewing on the other side of the mouth and choosing softer foods can reduce pressure on a painful tooth. Maintaining hydration and avoiding tobacco are also sensible steps for oral and general health.

Over-the-counter pain medicines can be useful for some adults, but suitability depends on age, pregnancy status, kidney, liver, stomach, heart, bleeding, and medication history. A pharmacist, dentist, or doctor can advise on safe options. Herbal products, including toothache plant, should not be used to postpone an appointment when pain lasts, returns, or gets worse.

Longer-term prevention focuses on regular dental check-ups, fluoride toothpaste, cleaning between teeth each day, limiting frequent sugary snacks and drinks, and addressing dry mouth, grinding, or smoking where relevant. These measures reduce the risk of common causes of tooth pain more effectively than temporary numbing remedies.

When to Seek Medical Care

A dental appointment should be arranged if tooth pain lasts more than a day or two, returns repeatedly, interferes with sleep or eating, or is associated with sensitivity that does not settle. Assessment is also advisable for bleeding gums, a loose filling or crown, a cracked tooth, pain when biting, persistent bad breath, or a mouth sore that does not heal.

Urgent dental or medical care is needed for facial or jaw swelling, fever, pus or a persistent bad taste in the mouth, swollen neck glands, or pain that is rapidly worsening. These symptoms can occur with a spreading dental infection. Prompt treatment is especially important for people with weakened immune systems or poorly controlled diabetes.

Emergency care is appropriate if swelling affects the eye or neck, or if there is difficulty breathing, swallowing, speaking, opening the mouth, or controlling saliva. These symptoms are uncommon but can signal a serious infection that needs immediate evaluation. A toothache plant product should not be used as a substitute for urgent care in these situations.

Discussing Herbal Products With a Dental Professional

People who choose to use toothache plant should tell their dentist or doctor about it, particularly if they use concentrated tinctures, capsules, or multi-ingredient herbal formulas. Bringing the product name or label can help the clinician identify possible ingredients, allergies, and safety concerns. This information is useful even when the product seems harmless or is used only occasionally.

A dental clinician can explain what is causing the pain and recommend treatment based on the individual tooth, gums, medical history, and preferences. In some cases, a dental problem can be treated early with a relatively simple procedure; delaying care may allow it to become more complex. The goal is not merely to reduce pain but to protect oral health and function.

Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat dental and oral health concerns for international patients. A qualified dental assessment remains the most reliable way to determine whether tooth pain needs restorative treatment, gum care, urgent infection management, or another form of support.

Frequently asked questions

Does toothache plant really numb tooth pain?

Toothache plant can create a tingling or short-lived numbing sensation in the mouth, mainly due to a compound called spilanthol. However, this effect may be temporary and does not treat the reason for the pain. Persistent or significant tooth pain should be checked by a dentist.

Can toothache plant cure a cavity or dental infection?

No. There is no reliable evidence that toothache plant cures cavities, repairs cracked teeth, treats gum disease, or eliminates a dental abscess. These conditions need diagnosis and cause-based dental treatment.

Is toothache plant safe to chew?

Some people eat small amounts of the plant as a food or use it traditionally, but medicinal use is not risk-free. It can irritate the mouth or trigger allergic reactions, especially in people sensitive to plants in the daisy family. Product strength and purity can vary considerably.

Who should avoid toothache plant?

People with known allergies to ragweed, chamomile, chrysanthemums, or related plants should avoid it unless advised otherwise by a clinician. Pregnant or breastfeeding people, children, and people taking regular medicines should seek professional advice before using herbal extracts because safety data are limited.

What is the fastest safe way to deal with a toothache?

The safest approach is to arrange a dental assessment to identify the cause. While waiting, gentle oral hygiene, avoiding trigger foods, and a cold compress on the outside of the face may help. A pharmacist or clinician can advise whether an over-the-counter pain medicine is appropriate for the individual.

When is a toothache an emergency?

A toothache needs urgent attention if there is facial or neck swelling, fever, pus, rapidly worsening pain, or difficulty opening the mouth. Emergency care is needed for trouble breathing or swallowing, swelling near the eye or neck, or inability to manage saliva. These signs may indicate a serious spreading infection.
