The most effective pill for tooth pain is ibuprofen (Advil, Motrin), either on its own or combined with acetaminophen (Tylenol). A 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. This combination is now the American Dental Association’s recommended first-line approach for toothaches.
Why Ibuprofen Works Best for Tooth Pain
Tooth pain is almost always driven by inflammation. When bacteria irritate the tissue inside or around a tooth, your body releases chemical signals called prostaglandins that amplify pain and swelling. Ibuprofen and other anti-inflammatory painkillers block the enzyme responsible for producing those prostaglandins, attacking the pain at its source. That’s why anti-inflammatory pills tend to work better for dental pain than options like acetaminophen or opioids, which dull pain signals but don’t reduce the underlying inflammation.
Acetaminophen works through a different pathway, primarily in the central nervous system. On its own it’s a reasonable painkiller, but it doesn’t do much for swelling. The real power comes from combining the two: ibuprofen quiets the inflammation at the tooth while acetaminophen blocks pain signals in the brain. Because they work on opposite ends of the pain pathway, the combined effect is greater than either pill alone.
Recommended Doses and Timing
The ADA’s clinical guidelines lay out two first-line options, both available without a prescription:
- Option 1: 400 mg ibuprofen alone, or 440 mg naproxen sodium (Aleve)
- Option 2: 400 mg ibuprofen (or 440 mg naproxen sodium) plus 500 mg acetaminophen
For moderate to severe pain, dental pain researchers recommend taking ibuprofen 400 to 600 mg plus acetaminophen 500 mg every six hours on a fixed schedule for the first 24 hours, then switching to the same combination as needed. Staying on a schedule matters during that first day because it keeps a steady level of the drug in your system rather than letting pain break through and trying to chase it.
In 2020, the FDA approved a combination pill containing 250 mg ibuprofen and 500 mg acetaminophen per two-caplet dose. It’s sold over the counter and simplifies the process if you don’t want to juggle two separate bottles.
Naproxen as an Alternative
Naproxen sodium (Aleve) is another anti-inflammatory option. Its main advantage is duration: a single dose lasts 8 to 12 hours compared to ibuprofen’s 4 to 6. If your pain is keeping you up at night, naproxen taken before bed may carry you through until morning. The trade-off is that it tends to kick in a bit more slowly than ibuprofen.
When You Can’t Take Anti-Inflammatories
Ibuprofen and naproxen aren’t safe for everyone. You should avoid them if you have a history of stomach ulcers, gastric bypass surgery, inflammatory bowel disease, or gastrointestinal bleeding. They’re also off-limits during pregnancy after 20 weeks, and people with significant kidney problems or those taking blood thinners need to steer clear.
If anti-inflammatories are ruled out, the ADA recommends acetaminophen alone at a full 1,000 mg dose. It won’t match the inflammation-fighting power of ibuprofen, but it’s gentler on the stomach and kidneys. Keep your total acetaminophen from all sources under 3,000 mg per day. If you have liver problems, that ceiling drops to 2,000 to 3,000 mg for moderate impairment and just 1,000 mg for severe liver disease. People who drink alcohol regularly should be especially cautious, as alcohol significantly increases the risk of liver damage from acetaminophen.
What About Prescription Painkillers?
Opioid painkillers like hydrocodone and oxycodone are no longer considered first-line treatment for tooth pain. The evidence is clear: the ibuprofen-acetaminophen combination provides better relief with fewer side effects. The ADA reserves opioids for cases where anti-inflammatories are contraindicated and acetaminophen alone isn’t enough. Even then, the guidance calls for the lowest effective dose for the shortest duration, which rarely exceeds three days.
If your dentist does prescribe an opioid, it will typically be combined with acetaminophen. Be careful not to double up on acetaminophen from separate sources, as this is one of the most common ways people accidentally exceed the daily limit. Opioids should also be avoided entirely during pregnancy and by anyone taking benzodiazepines (anti-anxiety medications), because the combination increases the risk of dangerous sedation.
Antibiotics and Tooth Pain
Antibiotics don’t directly relieve pain, but if your toothache is caused by an infection, they’re an essential part of treatment. The catch is timing: most people don’t notice a meaningful reduction in pain and swelling until 48 to 72 hours after starting antibiotics. You’ll still need pain-relieving pills to get through those first couple of days.
The standard first-choice antibiotics for dental infections are amoxicillin and penicillin. If you’re allergic to penicillin-type drugs, your dentist will typically prescribe azithromycin, clindamycin, or cephalexin instead. A full course usually runs five to seven days, sometimes up to 14. Finishing the entire course matters even after the pain fades, because stopping early can allow resistant bacteria to survive.
Dosing for Children
Children’s doses are based on weight, not age. For acetaminophen, the standard is 10 to 15 mg per kilogram of body weight every four to six hours, with a daily maximum of 75 mg per kilogram for kids two and older. For ibuprofen, the dose is 5 to 10 mg per kilogram every six to eight hours, with a cap of 40 mg per kilogram per day. Ibuprofen is typically avoided in infants under six months.
Two important restrictions apply to children specifically. Codeine is contraindicated in children under 12, and tramadol is contraindicated in anyone under 18. Both carry serious risks of breathing problems in young people.
What to Do Until the Pills Kick In
Most oral painkillers take 20 to 45 minutes to start working. While you wait, a few non-pill strategies can take the edge off. Applying a cold pack to the outside of your cheek (20 minutes on, 20 minutes off) constricts blood vessels and reduces swelling. Rinsing gently with warm salt water, about half a teaspoon of salt in eight ounces of water, can help clean the area and soothe irritated tissue. Keeping your head elevated, even while sleeping, reduces blood pressure to the area and can prevent the throbbing from intensifying.
One thing to skip: placing aspirin directly on your gums. This is an old home remedy that actually burns soft tissue and can make things worse. Aspirin only works when swallowed and absorbed through your digestive system.
