The most effective over-the-counter option for a toothache is ibuprofen, either alone or combined with acetaminophen. The American Dental Association recommends NSAIDs like ibuprofen as first-line therapy for acute dental pain, noting they actually outperform even opioid painkillers for this type of pain. Here’s how to use them effectively, along with other options that can help while you arrange dental care.
Why Ibuprofen Works Best for Tooth Pain
Toothaches are driven by inflammation. When the tissue inside or around a tooth becomes irritated or infected, your body ramps up production of compounds called prostaglandins that amplify pain and swelling. Ibuprofen blocks the enzyme responsible for making those compounds, attacking the pain at its source rather than just dulling the signal.
That’s why the ADA specifically recommends NSAIDs over other pain relievers for dental pain. A standard adult dose is 200 to 400 mg every four to six hours. Don’t exceed 1,200 mg in 24 hours unless directed by a doctor. Take it with food to reduce stomach irritation.
The Ibuprofen-Plus-Acetaminophen Strategy
If ibuprofen alone isn’t cutting it, adding acetaminophen creates a surprisingly powerful combination. A randomized clinical trial tested this approach in patients after wisdom tooth removal and found the combination provided significantly greater and faster pain relief than either drug alone across nearly every measure: time to meaningful relief, peak pain scores, and the need for additional painkillers.
The two drugs work through completely different pathways, so they complement rather than compete with each other. You can take them at the same time or alternate them. A common approach is 400 mg of ibuprofen with 500 mg of acetaminophen, repeating every six hours. For acetaminophen, keep your total daily intake under 3,000 mg to be safe (the absolute ceiling is 4,000 mg, but lower is better, especially if you drink alcohol or have a smaller frame). With 500 mg pills, that means no more than eight pills in 24 hours.
Topical Options for Targeted Relief
Over-the-counter numbing gels containing benzocaine (sold as Orajel and similar brands) can temporarily dull the area around the painful tooth. Apply a small amount directly to the gum near the tooth and it should start working within a minute or two. The relief is short-lived, usually 20 to 30 minutes, but it can bridge the gap while you wait for oral painkillers to kick in.
Clove oil is a natural alternative worth considering. Its active ingredient, eugenol, is a natural anesthetic that dentists have used for decades. One clinical trial in a dental emergency unit found eugenol was actually more effective than a prescription local anesthetic at reducing pain from severe tooth inflammation. To use it, put a drop or two on a cotton ball and hold it against the sore tooth and surrounding gum. The taste is strong and the sensation can be intense for a few seconds before the numbing sets in.
Salt Water Rinses
A warm salt water rinse won’t replace painkillers, but it reduces bacteria and draws fluid out of swollen tissue, which can ease pressure and discomfort. Mix one and a half teaspoons of salt into eight ounces of warm water. Swish it gently around the painful area for 30 seconds, then spit. You can repeat this one to three times per day.
This is especially useful if you have food trapped around the tooth or if the gum is swollen. It’s also one of the safest options for people who can’t take standard painkillers.
What to Give Children
For kids, the safe choices are children’s ibuprofen and children’s acetaminophen. The ADA’s guidelines for children mirror those for adults: ibuprofen alone or combined with acetaminophen is the recommended approach for dental pain.
Dose by your child’s weight, not age. If you don’t know the weight, age is a rough backup. Standard liquid acetaminophen for children comes in a concentration of 160 mg per 5 mL. Use the syringe that comes with the medicine, not a kitchen spoon. For children under 12, acetaminophen can be given every four hours, with no more than five doses in 24 hours. Don’t give extra-strength (500 mg) products to children under 12, and don’t give extended-release (650 mg) products to anyone under 18. Children under 2 should not receive acetaminophen without a doctor’s guidance.
Avoid combination products (medicines with more than one active ingredient) for children under 6.
Pain Relief During Pregnancy
Choosing a toothache remedy during pregnancy is more complicated than it used to be. The FDA previously categorized certain painkillers as generally safe in pregnancy, but reversed that position, stating the available research is too limited to make blanket recommendations. The current guidance from both the ADA and FDA is to discuss pain relief options with your obstetrician before taking anything, including over-the-counter medications.
Salt water rinses and cold compresses applied to the outside of the cheek are safe non-drug options to use in the meantime.
What Not to Take
Aspirin works on a similar pathway to ibuprofen, but it’s a poor choice for toothaches. It thins the blood more aggressively, which is a problem if you need a dental procedure soon. Never place an aspirin tablet directly on your gum, as this can burn the tissue.
Don’t combine two different NSAIDs (for example, ibuprofen and naproxen) at the same time. They compete for the same pathway and increase the risk of stomach bleeding without adding much pain relief. Combining an NSAID with acetaminophen is fine because they work differently. Combining two NSAIDs is not.
Signs You Need Emergency Care
A toothache that responds to over-the-counter medication still needs a dental visit, but it’s not an emergency. Certain symptoms, however, signal that an infection may be spreading beyond the tooth. Go to an emergency room if you have a fever along with facial swelling, especially if you can’t reach your dentist. Difficulty breathing or swallowing with tooth pain means the infection may have spread into your jaw, throat, or neck, and that requires immediate treatment.
Swelling that’s visibly distorting your face, pain that doesn’t respond at all to maximum doses of ibuprofen and acetaminophen together, or a foul-tasting discharge in your mouth all suggest a dental abscess that’s progressing and needs professional drainage, not just pain management at home.
