The most effective medicine for a toothache is ibuprofen combined with acetaminophen, taken together. A large review of data from over 58,000 dental patients found that 400 mg of ibuprofen plus 1,000 mg of acetaminophen outperformed every other pain regimen tested, including those containing opioids. This combination is now the first-line recommendation from the American Dental Association for acute dental pain.
Why the Combination Works So Well
Ibuprofen and acetaminophen relieve pain through completely different pathways, which is why pairing them is more effective than doubling up on either one alone. Ibuprofen is an anti-inflammatory. It works at the site of the toothache itself, reducing the swelling and inflammation that press on nerve endings inside or around the tooth. Acetaminophen works in the brain and spinal cord, dampening pain signals before you consciously feel them.
Taking both means you’re blocking pain at both ends: at the tooth and in the brain. This dual approach is why the combination consistently beats single-drug options in clinical studies. You can take them at the same time since they’re processed differently by the body and don’t interact with each other.
Dosing for Adults
For over-the-counter use, the standard approach is 400 mg of ibuprofen plus 1,000 mg (two extra-strength tablets) of acetaminophen. You can repeat this every six to eight hours as needed. There is also a combination tablet available that contains 125 mg of ibuprofen and 250 mg of acetaminophen per pill. The dose for that product is two tablets every eight hours, with a maximum of six tablets per day.
If you only have one of these medications available, ibuprofen on its own is generally the better choice for tooth pain because most toothaches involve inflammation. Acetaminophen alone can take the edge off, but it won’t address the swelling driving the pain.
Topical Options for Faster Relief
While oral painkillers take 20 to 30 minutes to kick in, topical numbing agents work within about five minutes. Benzocaine gels (sold as Orajel and similar brands) are the most common option at pharmacies. You apply a small amount directly to the gum around the painful tooth for temporary numbness.
Clove oil is a natural alternative worth considering. It contains eugenol, an oily compound that dentists have used for decades as both a painkiller and antiseptic. A clinical trial testing clove gel against 20% benzocaine gel on 73 volunteers found no significant difference in pain reduction between the two. Both performed significantly better than placebo. You can dab a small amount of clove oil onto a cotton ball and hold it against the sore area. It tastes strong, but it works.
Who Should Avoid Ibuprofen
Ibuprofen isn’t safe for everyone. You should skip it and use acetaminophen alone if you have a history of stomach ulcers or gastrointestinal bleeding, kidney disease, aspirin-sensitive asthma, bleeding or platelet disorders, or if you’ve had gastric bypass surgery. People over 60 face a higher risk of stomach complications from ibuprofen as well.
Several common medications also interact poorly with ibuprofen. Blood thinners like warfarin increase bleeding risk. Lithium levels can rise to toxic concentrations. If you take diuretics for heart failure or liver disease, adding ibuprofen raises the chance of kidney damage. SSRIs (commonly prescribed for depression and anxiety) combined with ibuprofen increase the risk of stomach ulcers, so you should limit use to four days or fewer. If any of these apply to you, acetaminophen alone is a safer choice for managing tooth pain at home.
Toothache Medicine for Children
For children, acetaminophen is the go-to option. Liquid formulations come in a standardized concentration of 160 mg per 5 mL. Dose by your child’s weight rather than age for accuracy, and use an oral syringe to measure it (kitchen spoons are unreliable). Children under 12 can take a dose every four hours, up to five doses in 24 hours. Children under 2 should not receive acetaminophen without a doctor’s guidance.
Ibuprofen is also available for children over 6 months old, but combination products containing more than one active ingredient should not be given to children under 6. Extra-strength (500 mg) acetaminophen products are not appropriate for children under 12, and extended-release versions are restricted to ages 18 and older.
When Pain Medicine Isn’t Enough
For severe pain that doesn’t respond to the ibuprofen-acetaminophen combination, dentists may add a low-dose opioid for a short course, typically limited to three days. But this is reserved for situations where other options have been maximized or can’t be used. Opioids are less effective than ibuprofen for dental pain on average and carry more side effects, which is why guidelines position them as a last resort rather than a first choice.
It’s also important to understand that pain medication treats the symptom, not the cause. A toothache usually signals an underlying problem: a cavity that has reached the nerve, an infection, or a crack in the tooth. The ADA recommends dental procedures like root canals or drainage rather than antibiotics for most of these conditions. Antibiotics only become necessary when the infection has spread beyond the tooth itself, causing fever or general feelings of illness.
Signs You Need Emergency Care
Most toothaches can be managed at home for a day or two while you arrange a dental visit. But certain symptoms mean you shouldn’t wait. Bleeding that won’t stop, pain that doesn’t improve with medication, swelling that spreads to your eye or neck, difficulty breathing or swallowing, or any broken facial bones all require immediate emergency care. These can signal infections or injuries that progress quickly and need hands-on treatment, not just stronger painkillers.
