The fastest way to help a toothache at home is to take an anti-inflammatory painkiller like ibuprofen (400 mg) and rinse with warm salt water. These two steps address both the pain and the inflammation driving it. But what you do next depends on what’s causing the toothache, because the pain is almost always a signal that something needs professional treatment.
Over-the-Counter Pain Relief That Works Best
For dental pain, anti-inflammatory medications outperform every other option, including opioids. The CDC notes that NSAIDs are more effective than opioids for surgical dental pain, which makes over-the-counter options your strongest first move. Clinical guidelines recommend 400 mg of ibuprofen or 440 mg of naproxen sodium as the go-to starting point. If that’s not enough on its own, adding 500 mg of acetaminophen alongside the ibuprofen creates a combination that targets pain through two different pathways. You can safely take both at the same time because they’re processed differently by the body.
Stay within the daily maximums: 2,400 mg of ibuprofen, 1,100 mg of naproxen sodium, or 4,000 mg of acetaminophen per day. Take ibuprofen with food to protect your stomach. If you have kidney problems or stomach ulcers, acetaminophen alone is the safer choice. Avoid aspirin if there’s any bleeding around the tooth, since it thins the blood and can make things worse.
Salt Water Rinses and Other Home Remedies
A warm salt water rinse is one of the simplest and most effective things you can do while waiting for a dental appointment. Mix about half a teaspoon of salt into eight ounces of warm water, swish gently for 30 seconds, and spit. The salt shifts your mouth’s pH toward alkaline, creating an environment where bacteria struggle to survive. It also helps draw fluid out of swollen gum tissue, which reduces pressure and pain. You can repeat this several times a day.
Clove oil is the most evidence-backed natural remedy for tooth pain. Its active compound, eugenol, makes up nearly 89% of clove oil and works as a local anesthetic comparable to standard numbing agents used in clinical settings. To use it, soak a small cotton ball in clove oil and hold it against the painful tooth for a few minutes. The numbing effect kicks in quickly but doesn’t last long, so treat it as a bridge to real treatment rather than a solution. The taste is intense and slightly burning, which is normal.
A cold compress on the outside of your cheek (20 minutes on, 20 minutes off) helps with swelling and provides some numbing. Avoid placing heat on a toothache, especially if there’s any chance of infection, as warmth can accelerate swelling.
Topical Numbing Gels: Use With Caution
Over-the-counter gels containing benzocaine can temporarily numb the area around a painful tooth. However, the FDA has issued significant safety warnings about these products. Benzocaine can cause a condition called methemoglobinemia, where the blood’s ability to carry oxygen drops dangerously low. This is rare in adults but serious enough that the FDA has ordered these products off the market entirely for children under 2 years old. For adults and older children, use them sparingly and follow the label directions. Clove oil is a reasonable alternative if you’d rather avoid the risk.
What Your Pain Pattern Tells You
Not all toothaches are the same, and the type of pain you’re experiencing offers real clues about what’s going on inside the tooth. Understanding this helps you gauge how urgently you need to see a dentist.
If the pain only shows up when you eat or drink something hot, cold, or sweet, and it fades within a few seconds after the trigger is removed, you’re likely dealing with early-stage inflammation of the tooth’s nerve. This is often reversible with treatment like a filling or crown, and the tooth can usually be saved without major intervention. A desensitizing toothpaste containing potassium nitrate can help in the meantime. Studies show measurable pain reduction within two weeks of regular use, with continued improvement at four weeks.
If the pain lingers for minutes after a trigger, strikes spontaneously (especially at night), or feels sharp and electric, the nerve damage has likely progressed further. About 76% of people with this type of inflammation report pain triggered by cold, and 80% say it disturbs their sleep. At this stage, the tooth typically needs a root canal or extraction.
If your tooth feels “too high” when you bite down, the pain is constant and throbbing, and chewing makes it significantly worse, the infection has likely spread beyond the tooth’s nerve into the surrounding bone and tissue. Swelling is the hallmark sign of a full abscess. Both advanced nerve inflammation and abscesses produce severe pain, with patients rating it 8 out of 10 on average.
When a Toothache Becomes an Emergency
Most toothaches need a dentist within a few days. Some need an emergency room right now. Go to the ER or call emergency services if you have difficulty breathing, speaking, or swallowing. The same applies if you notice swelling around your eye, sudden vision problems, significant swelling spreading across your face or floor of your mouth, or difficulty opening your mouth. These are signs that a dental infection is spreading into areas where it can block your airway or reach your brain, and they require immediate medical intervention.
Fever combined with facial swelling also warrants urgent care, even if you can still breathe and swallow normally. A dental abscess won’t resolve on its own, and antibiotics alone rarely clear one without drainage or treatment of the source tooth.
What a Dentist Will Actually Do
The definitive fix for a toothache depends on the cause, but the two most common paths are root canal therapy and extraction.
A root canal removes the infected or damaged nerve tissue from inside the tooth, cleans the interior, and seals it. The tooth stays in your mouth and functions normally afterward. Success rates reach up to 97%, and even teeth that need a second root canal treatment still have success rates of 74% to 98%. The procedure itself is done under local anesthesia and typically takes one to two visits. Most people are surprised that it hurts less than the toothache that brought them in.
Extraction is the alternative when a tooth is too damaged to save. If you choose to replace the extracted tooth with an implant, studies show the long-term success rate is about 95%, essentially identical to a root canal with a crown. The choice between saving and removing a tooth depends on how much healthy tooth structure remains, the location in your mouth, and your budget.
For abscesses, the dentist will also drain the infection and may prescribe antibiotics if the infection has spread beyond the tooth itself. Pain relief after professional treatment is typically dramatic and fast.
Mistakes That Make a Toothache Worse
Placing aspirin directly on your gum tissue is a persistent home remedy that causes chemical burns. Swallow your pain medication normally. Avoid chewing on the painful side, and skip very hot, very cold, or sugary foods and drinks that can trigger additional nerve pain. Don’t ignore a toothache that “goes away on its own.” When a severely painful tooth suddenly stops hurting without treatment, it often means the nerve has died, not that the problem is resolved. The infection is still there and will eventually cause an abscess or worse.
Alcohol swished around a sore tooth provides minimal numbing and irritates inflamed tissue. The same goes for hydrogen peroxide at household concentrations, which can damage soft tissue with repeated use.
