A toothache rarely waits for a convenient time, and most home remedies work best as short-term relief while you arrange to see a dentist. The good news: a combination of over-the-counter pain relievers, salt water rinses, and cold therapy can significantly reduce pain within minutes. Here’s what actually works, how to do it properly, and what signals mean you need professional help right away.
Start With the Right Pain Relievers
Over-the-counter ibuprofen and acetaminophen are the most effective tools you have at home, and combining them works better than either one alone. Because they block pain through different pathways, taking both creates a stronger effect. A large review of data from over 58,000 dental patients found that 400 mg of ibuprofen combined with 1,000 mg of acetaminophen outperformed every opioid-containing painkiller tested, with fewer side effects.
For mild pain, 200 to 400 mg of ibuprofen every four to six hours is typically enough. For moderate to severe pain, take 400 to 600 mg of ibuprofen alongside 500 mg of acetaminophen every six hours. The FDA has also approved a combination product containing both drugs in a single caplet, available without a prescription. Keep your total acetaminophen intake under 4,000 mg per day to protect your liver. If you have stomach ulcers, kidney problems, or are on blood thinners, stick with acetaminophen alone.
Salt Water Rinse
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 draws bacteria away from infected tissue. You can repeat this several times a day, especially after meals. It won’t fix the underlying problem, but it keeps the area cleaner and can ease throbbing while your pain relievers kick in.
Apply a Cold Compress
Hold an ice pack or bag of frozen vegetables against the outside of your cheek, over the painful area, for 10 to 20 minutes at a time. Place a thin cloth between the ice and your skin to prevent frostbite. Cold therapy constricts blood vessels, which reduces swelling and numbs the nerve signals causing pain. Wait at least 20 minutes before reapplying. This is especially useful if you notice any visible swelling along your jaw or cheek.
Clove Oil for Targeted Numbing
Clove oil contains eugenol, a natural anesthetic that dentists have used for decades. It numbs on contact and has mild anti-inflammatory effects. Never apply it full strength. Mix a few drops of clove oil with about a teaspoon of olive oil, then dip a cotton ball or swab into the mixture. Gently dab it on the painful tooth and surrounding gum. You should feel a numbing sensation within a few minutes. If it burns or feels too intense, remove the cotton and rinse your mouth with water.
Other Home Remedies Worth Trying
A used peppermint tea bag, cooled slightly so it’s still warm, can soothe sensitive gums when held against the sore spot. Black tea bags work too, since tannins in black tea help reduce swelling.
Fresh garlic releases a compound called allicin when crushed or chewed, which kills bacteria that form plaque and contribute to infection. Crushing a clove of garlic and holding it near the affected tooth may provide some antibacterial benefit and reduce gum irritation. The taste is strong, and you’ll want to brush about 30 minutes afterward.
Hydrogen peroxide rinses can also help with infection. Mix equal parts 3% hydrogen peroxide (the brown bottle from any drugstore) and water to create a 1.5% solution. Swish for 30 seconds and spit completely. Never swallow it, and stop if you notice gum redness or mouth irritation.
Why Toothaches Get Worse at Night
If your tooth pain spikes at bedtime, it’s not your imagination. Lying flat sends more blood to your head, which increases pressure around the inflamed tooth. Propping yourself up with an extra pillow or two can reduce that blood pooling enough to let you fall asleep. Combine elevation with a dose of ibuprofen and acetaminophen about 30 minutes before bed for the best chance at a full night’s rest.
One Remedy to Avoid
Benzocaine gels, once a standard recommendation for tooth pain, carry a rare but serious risk. They’ve been linked to a condition called methemoglobinemia, which reduces the amount of oxygen your blood can carry. The Mayo Clinic no longer recommends applying benzocaine directly to teeth and gums.
Signs You Need Emergency Care
Home remedies are a bridge, not a solution. Pain that lasts more than a day or two, or that intensifies despite medication, means something is progressing. A tooth abscess, which is a pocket of infection at the root, can spread to your jaw, neck, and beyond.
Get to an emergency room if you experience any of the following alongside your toothache:
- Fever combined with facial or neck swelling
- Difficulty breathing or swallowing
- Swollen, tender lymph nodes under your jaw
- A sudden rush of foul-tasting, salty fluid in your mouth (a sign the abscess has ruptured)
- Severe, constant throbbing that radiates to your ear or neck
Red gums, pain when biting, or discharge around the tooth all point to active infection that home care alone won’t resolve. These situations need antibiotics and professional treatment to prevent the infection from reaching deeper tissues.
