Clove is the most effective and well-studied herb for toothache pain, but several other plants can also provide temporary relief. The key compound in clove, eugenol, works by interrupting nerve signals that carry pain from the tooth to the brain. While no herb replaces dental treatment for the underlying cause, these options can reduce pain while you wait for an appointment.
Clove Oil: The Strongest Option
Clove has been used for dental pain for centuries, and it remains the herb with the most evidence behind it. Eugenol, the active compound, interferes with the electrical signals nerves use to transmit pain. This creates a localized numbing effect that kicks in within minutes. You can find eugenol listed as an ingredient in some over-the-counter dental pain products for this reason.
To use it at home, dip a small cotton ball in clove oil and place it directly on or near the painful tooth. You can also chew gently on a whole dried clove near the affected area to release the oil naturally. The relief typically lasts 30 minutes to a couple of hours.
One important caution: undiluted clove oil can irritate or damage soft tissue. Cases of oral ulcers, burning mouth syndrome, and gum irritation have been documented after prolonged or excessive use. A 68-year-old woman who chewed cloves daily and used a eugenol mouthwash developed burning mouth syndrome that persisted for two years, only resolving when she stopped. Dilute clove oil with a carrier oil like olive or coconut oil before applying it, and limit use to a few times per day for short periods.
Peppermint for Mild to Moderate Pain
Peppermint oil contains 29 to 48% menthol, which acts as a topical pain reliever. Menthol activates cold-sensing receptors in your tissue, creating a cooling sensation that competes with and partially overrides pain signals. The effect is gentler than clove but still noticeable.
Soak a cotton ball in peppermint oil and hold it against the sore tooth, or brew a strong peppermint tea, let it cool slightly, and swish it around the affected area. A cooled peppermint tea bag pressed against the gum can also deliver the compounds directly where they’re needed. For inflamed gums specifically, peppermint leaf preparations used as a mouthwash can help reduce swelling.
Garlic as an Antimicrobial Option
Garlic’s pain-relieving reputation comes from allicin, a sulfur compound released when you crush or chop a fresh clove. Allicin has demonstrated antibacterial activity against two of the main bacteria responsible for tooth decay: Lactobacillus acidophilus and Streptococcus mutans. It also appears to reduce pain by lowering levels of inflammatory compounds your body produces in response to infection.
To use garlic, crush a fresh clove to activate the allicin (this is essential, as whole garlic contains the precursor but not the active compound itself). Place the crushed garlic near the painful tooth or mix it with a small amount of salt. Be aware that raw garlic is potent and can cause a chemical burn on delicate gum tissue if left in place too long. Keep contact brief, no more than a few minutes, and rinse your mouth afterward.
Thyme Oil for Bacterial Pain
Thyme essential oil gets its antibacterial power from two phenolic compounds, thymol and carvacrol, which together make up the bulk of the oil. These compounds inhibit a wide range of harmful bacteria, including Staphylococcus aureus. Thymol is already used as an ingredient in some commercial mouthwashes.
Add a drop or two of thyme essential oil to a small amount of carrier oil and apply it to the affected tooth with a cotton ball. You can also add a few drops to warm water and use it as a rinse. Like clove oil, undiluted thyme oil is too strong for direct application to gums and should always be diluted first.
Guava Leaves for Swollen Gums
If your toothache involves red, swollen, or bleeding gums, guava leaves are worth considering. They contain quercetin, a flavonoid with anti-inflammatory and antimicrobial properties, along with other compounds like gallic acid and kaempferol that contribute analgesic effects. Traditionally, guava leaf preparations have been used as a gargle for periodontal symptoms.
Chew fresh guava leaves slowly until the juices coat the painful area, or boil a handful of leaves in water for about 20 minutes, strain, and use the cooled liquid as a mouth rinse. This is one of the milder options and carries minimal risk of tissue irritation.
The Toothache Plant (Spilanthes)
Less commonly known in Western countries, Spilanthes acmella has been called the “toothache plant” for good reason. It contains spilanthol, a compound that causes a distinctive tingling and numbing sensation when it contacts oral tissue. Animal studies show it produces local anesthetic effects by blocking sodium channels in nerve cells, the same basic mechanism used by pharmaceutical dental anesthetics. Its onset is slower than clinical anesthetics, but it provides meaningful pain relief.
Spilanthes is available as tinctures or dried flower heads from herbal suppliers. Chewing the flower heads (sometimes called “buzz buttons”) directly is the most traditional application. The tingling feeling is intense and unusual but harmless.
Saltwater Rinse as a Simple Baseline
Before reaching for any herb, a warm saltwater rinse is the simplest first step. Dissolve half a teaspoon of salt in a cup of warm water and swish it gently around the painful area for 30 seconds before spitting. Salt water reduces inflammation and helps draw bacteria away from infected tissue through osmosis. It won’t numb pain the way clove or spilanthes will, but it cleans the area and can reduce the throbbing sensation that comes with swelling. Repeat every few hours as needed.
When Herbs Are Not Enough
These remedies manage symptoms temporarily. They do not treat cavities, abscesses, or cracked teeth. Pain lasting more than a day or two, fever, swelling in the face or jaw, red gums, pain when biting down, or a foul taste in your mouth all point to an infection that needs professional treatment. Difficulty breathing or swallowing alongside tooth pain is a medical emergency, as it can signal a spreading infection that requires immediate care.
