Abscessed Tooth Home Remedies: What Helps and What You Still Need

Salt Water Rinse

Dissolve half a teaspoon of regular table salt in a cup of warm (not hot) water. Gently swish the solution around the affected area for 30 seconds, then spit it out. Repeat 2 to 3 times per day. Salt water helps draw infection toward the surface, reduces bacteria in the mouth, and can temporarily ease pain. This is one of the simplest and most widely recommended first steps.

Cold Compress

Wrap ice or a cold pack in a thin towel and hold it against the outside of your cheek near the painful area. Apply for 15 to 20 minutes on, then 15 to 20 minutes off. Cold helps reduce swelling and has a mild numbing effect. Avoid placing ice directly on the skin.

Over-the-Counter Pain Medication

Ibuprofen (Advil, Motrin) is especially useful for abscess pain because it reduces both pain and inflammation. Follow the dosage directions on the label. Acetaminophen (Tylenol) can be taken in addition to ibuprofen if one medication alone is not enough. Do not exceed the maximum daily dose of either medication.

Avoid aspirin for dental pain if there is any chance you may need a procedure soon, as aspirin thins the blood and can increase bleeding.

Clove Oil (Eugenol)

Clove oil contains eugenol, a compound with natural anesthetic and antibacterial properties. It has been used in dentistry for decades as a temporary pain reliever. Apply a small amount to a cotton ball and hold it against the painful tooth and gum for a few minutes. You can reapply every 2 to 3 hours as needed.

Clove oil is available at most pharmacies and health food stores. Use it sparingly, as undiluted clove oil can irritate the gum tissue if used excessively.

Garlic

Garlic contains allicin, a compound with antibacterial properties. Crush a fresh garlic clove to release the allicin, then apply the crushed garlic to the affected area for a few minutes. Some people mix crushed garlic with a small amount of salt. The evidence for garlic as a dental remedy is limited, but it has a long history of traditional use and is unlikely to cause harm when used briefly.

Other Options That May Provide Relief

• Peppermint tea bags: Steep a peppermint tea bag, let it cool slightly, then hold it against the sore area. Peppermint has mild numbing properties.
• Hydrogen peroxide rinse: Mix equal parts 3% hydrogen peroxide and water. Swish gently and spit out. Do not swallow. This can help reduce bacteria.
• Elevating your head while sleeping can reduce throbbing by decreasing blood flow to the area.
• Avoiding very hot, very cold, and sweet foods that may trigger or worsen pain.

Antibiotics Alone Cannot Cure an Abscess

This is one of the most important things to understand about tooth abscesses. Antibiotics can reduce the bacterial infection in the surrounding tissue, and your dentist may prescribe them to help control a severe infection before treatment. However, the core of the abscess is a pocket of pus and dead tissue inside the tooth or at the root tip. Antibiotics cannot penetrate this pocket effectively.

Without drainage (through a root canal, incision, or extraction), the abscess will return once the antibiotic course ends. Repeated courses of antibiotics without definitive treatment also contribute to antibiotic resistance.

Placing Aspirin on the Tooth

Holding an aspirin tablet directly against the gum or tooth is an old folk remedy that does not work and causes harm. Aspirin is acidic and will cause a chemical burn on the gum tissue, creating a painful white lesion. Aspirin only works as a pain reliever when swallowed and absorbed through the digestive system.

Waiting for It to Go Away

A tooth abscess will not resolve on its own. Even if the pain temporarily decreases (which can happen if the abscess drains on its own through a small opening in the gum), the infection is still present. An abscess that seems to improve without treatment has not healed. The infection remains at the root of the tooth and will flare up again, often worse than before.

Seek Emergency Care If You Have

These symptoms may indicate that the infection is spreading to deeper tissue spaces in the head and neck. In an emergency room, doctors can administer IV antibiotics and, if necessary, surgically drain the infection. You will then need follow-up dental treatment to address the source tooth.

• Fever of 101 F (38.3 C) or higher
• Swelling in your face, under your eye, or in your neck
• Difficulty swallowing or breathing
• Swelling under the tongue or in the floor of the mouth
• Rapid spread of swelling over a few hours
• Feeling generally very unwell, confused, or lightheaded

Root Canal Treatment

A root canal removes the infected pulp tissue from inside the tooth, cleans and disinfects the canal system, and seals it to prevent reinfection. An endodontist (root canal specialist) performs this procedure under local anesthesia. Despite its reputation, a root canal performed with modern techniques and anesthesia is no more uncomfortable than getting a filling. The tooth is then restored with a crown.

Incision and Drainage

If the abscess has formed a visible swelling on the gum, the dentist may make a small incision to drain the pus before starting root canal treatment. This provides immediate pressure relief and helps the antibiotics work more effectively. Drainage alone is not a final treatment; the tooth still needs a root canal or extraction.

Tooth Extraction

If the tooth is too damaged to be saved (severe fracture, extensive decay, or previous failed treatment), extraction removes the source of infection entirely. After extraction and healing, the missing tooth can be replaced with a dental implant or bridge. Your dentist or endodontist will discuss whether the tooth can be saved before recommending extraction.

Cost of Abscess Treatment

Root canal treatment typically ranges from $700 to $1,500 depending on the tooth. Molars with more canals cost more than front teeth. A dental crown to restore the tooth after a root canal adds $800 to $1,800. Extraction is generally less expensive, ranging from $150 to $400 for a simple extraction. Costs vary by location, provider, and case complexity. Most dental insurance plans cover a portion of both root canal treatment and extractions.
