A toothache rarely picks a convenient time to strike, but several home remedies can dial down the pain until you get to a dentist. The most effective immediate step is combining a saltwater rinse with over-the-counter pain relievers, then layering on cold compresses or topical numbing agents as needed. None of these fixes treat the underlying cause, but they can make the wait bearable.
Saltwater Rinse for Quick Relief
A warm saltwater rinse is the simplest first move. Mix 1 teaspoon of salt into 8 ounces of warm water, swish it around the painful area for 30 seconds, and spit. If your mouth is already raw or tender, cut the salt to half a teaspoon for the first day or two. You can repeat this several times a day, especially after eating, to keep the area clean and reduce bacteria around the tooth.
Saltwater works because it temporarily draws fluid out of inflamed tissue, which reduces swelling and eases pressure on the nerve. It also creates an environment that’s harder for bacteria to thrive in. The relief is temporary, but repeating it throughout the day keeps the pain more manageable.
Over-the-Counter Pain Medication
Ibuprofen is generally the best first choice for a toothache because it reduces both pain and inflammation. If ibuprofen alone isn’t enough, you can alternate it with acetaminophen. Combination tablets containing 250 mg acetaminophen and 125 mg ibuprofen are available over the counter. The standard adult dose is two tablets every eight hours, with a maximum of six tablets per day.
One critical safety note: never place an aspirin tablet directly on your gum or against the painful tooth. Aspirin contains acetylsalicylic acid, which causes a chemical burn on soft tissue. The result is a white, painful irritation on your gums that can hurt for several days. Swallow pain relievers normally instead.
Cold Compress on the Outside
If the side of your face is swollen or the pain is throbbing, hold a cold pack or bag of ice against the outside of your cheek for 10 to 20 minutes at a time, with a thin cloth between the ice and your skin. Take a break for at least 20 minutes before reapplying. Cold narrows blood vessels in the area, which reduces swelling and slows the pain signals reaching the nerve. This is especially useful during the first day or two when inflammation peaks.
Clove Oil as a Topical Numbing Agent
Clove oil contains a compound called eugenol that acts as a mild natural anesthetic. When applied in diluted form, it temporarily numbs the affected area, reduces inflammation, and has some antibacterial activity. To use it, put a drop or two of clove oil on a small cotton ball and hold it gently against the painful tooth for a few minutes. If the oil feels too strong or stings, dilute it with a small amount of olive oil or coconut oil before applying.
You can find clove oil at most pharmacies and health food stores. It won’t fix the problem, but the numbing effect can last 20 to 30 minutes and bridge the gap while you wait for pain relievers to kick in.
Hydrogen Peroxide Rinse
A diluted hydrogen peroxide rinse can help kill bacteria and temporarily ease pain, particularly if there’s an infection brewing. Start with the standard 3% hydrogen peroxide sold in brown bottles at drugstores, then mix equal parts peroxide and water to bring it down to 1.5%. Swish for no more than 90 seconds and spit it all out. Do not swallow any of it. Undiluted hydrogen peroxide can burn your mouth and internal organs, so the dilution step matters.
If you notice increased redness, irritation, dizziness, or nausea after using this rinse, stop immediately.
Garlic Paste
Fresh garlic releases a compound called allicin when crushed, which has antibacterial properties that may help with infection-related toothaches. Crush a peeled clove into a paste and mix it with a small pinch of salt, then apply the mixture to the affected tooth with a clean finger or cotton swab. You can also gently chew a garlic clove on the painful side and let it rest against the tooth.
Be prepared for a strong burning sensation in your mouth from the raw garlic. And if you have a visible cavity, avoid pushing garlic deep into the hole where it can get stuck and cause more irritation.
Sleeping With a Toothache
Toothaches famously get worse at night. There’s a straightforward reason: when you lie flat, blood pools in your head, increasing inflammation and pressure around the affected tooth. That’s why a dull ache during the day can turn into intense throbbing the moment you lie down.
The fix is simple. Prop yourself up with an extra pillow or two so your head stays elevated above your heart. This reduces blood flow to the area and takes some pressure off the nerve. Combine this with a dose of ibuprofen taken about 30 minutes before bed, and you’ll have a much better shot at sleeping through the night. A saltwater rinse right before bed also helps keep the area clean while you sleep.
What Not to Use on Children
If your child has a toothache, avoid topical numbing gels that contain benzocaine or lidocaine. The FDA has issued direct warnings that these products should not be used for dental pain in children. Benzocaine can cause a condition called methemoglobinemia, where red blood cells lose their ability to carry oxygen effectively. This is rare but potentially fatal. Children’s ibuprofen or acetaminophen, taken orally at the dose listed on the package for their weight, is safer.
Signs You Need Emergency Care
Most toothaches can wait a day or two for a dental appointment. But certain symptoms mean the infection may be spreading beyond the tooth, and that requires immediate attention. Go to an emergency room if you have a fever combined with facial swelling, especially if you can’t reach your dentist. Difficulty breathing or swallowing is a more urgent red flag, as it can mean the infection has spread into your jaw, throat, or neck.
Swelling that moves from the gum line up into your cheek, under your eye, or down into your neck is another sign things are progressing. A tooth abscess that spreads can become life-threatening, so don’t wait on those symptoms even if the pain itself feels manageable.
