Ibuprofen (Advil, Motrin) is the single most effective over-the-counter option for toothache pain, outperforming acetaminophen, aspirin, and even acetaminophen with codeine in clinical studies. For stronger relief, you can alternate ibuprofen with acetaminophen (Tylenol) every three hours, which keeps pain suppressed more consistently than either drug alone. Below is a full breakdown of what works, how to use it safely, and when the pain signals something more serious.
Why Ibuprofen Works Best
Most toothaches involve inflammation, whether from an infection, a crack, or irritated nerve tissue deep inside the tooth. Ibuprofen is an anti-inflammatory, so it targets the source of the pain rather than just masking the sensation. At 400 mg (two standard OTC tablets), it consistently outperforms 650 mg of aspirin, 600 mg of acetaminophen, and even combinations of aspirin and acetaminophen together. It also provides longer-lasting relief per dose than most other OTC options.
Take 400 mg every six hours with food, since ibuprofen can upset your stomach on its own. Do not exceed 3,200 mg in 24 hours. If you have kidney disease, heart failure, high blood pressure, or liver disease, or you take blood pressure medications like ACE inhibitors or diuretics, skip ibuprofen entirely and use acetaminophen instead.
The Alternating Schedule for Severe Pain
When a single drug isn’t cutting it, alternating ibuprofen and acetaminophen every three hours gives you nearly continuous peak pain relief. Because these two drugs work through completely different mechanisms, they complement each other without increasing side-effect risk the way doubling up on one drug would. A practical schedule looks like this:
- 6:00 AM: Ibuprofen 400 mg with food
- 9:00 AM: Acetaminophen 1,000 mg
- 12:00 PM: Ibuprofen 400 mg with food
- 3:00 PM: Acetaminophen 1,000 mg
- 6:00 PM: Ibuprofen 400 mg with food
- 9:00 PM: Acetaminophen 1,000 mg
Stay under 4,000 mg of acetaminophen in any 24-hour period, and under 3,200 mg of ibuprofen. If you drink alcohol regularly, your safe limit for acetaminophen is lower, so cut back accordingly.
Topical Options: Clove Oil and Numbing Gels
Clove oil contains 60% to 92% eugenol, a natural compound that numbs tissue on contact and has mild antibacterial properties. Dentists have used eugenol-based preparations for over a century. To use it at home, mix 3 to 5 drops of clove oil into one teaspoon of an edible carrier oil like olive or coconut oil. Dip a cotton ball into the mixture and press it gently against the gums around the painful tooth (not directly on the tooth surface). Hold it in place for a few minutes. The numbing effect kicks in quickly and typically lasts 20 to 30 minutes.
Benzocaine gels (like Orajel) are another topical option for adults. They numb the area on contact and can help you get through the worst spikes of pain. However, the FDA has warned that benzocaine can cause a rare but life-threatening condition called methemoglobinemia, in which blood loses its ability to carry oxygen effectively. These products should never be used on children under 2 years old. For older children and adults, follow the package directions carefully and don’t apply more than directed.
Salt Water Rinse for Swelling
A warm salt water rinse won’t stop the pain on its own, but it reduces bacterial load and helps draw out minor swelling around an inflamed tooth. Mix one teaspoon of table salt and one teaspoon of baking soda into four cups of warm water. Swish gently for 30 seconds and spit. You can repeat this every four to six hours. It’s especially useful if you notice puffy or tender gums around the sore tooth, and it’s safe to use alongside any of the medications above.
Who Should Avoid NSAIDs
Ibuprofen, aspirin, and naproxen all belong to the same class of drugs (NSAIDs), and they share the same list of people who shouldn’t take them. If you have chronic kidney disease with an eGFR below 60, heart failure, liver disease, or uncontrolled high blood pressure, stick with acetaminophen for pain relief. The same applies if you take ACE inhibitors, ARBs, or diuretics for blood pressure, since NSAIDs can interfere with how those medications work and reduce blood flow to the kidneys.
Aspirin at doses above 325 mg per day carries the same kidney risks as ibuprofen, plus it should never be given to anyone under 19 because of the risk of Reye’s syndrome, a rare but dangerous condition affecting the brain and liver. For children, ibuprofen at 10 mg per kilogram of body weight is the standard recommendation and performs at least as well as acetaminophen with codeine in studies, with fewer side effects and better functional recovery.
When Toothache Pain Signals an Emergency
A toothache that responds to OTC medication and stays localized is uncomfortable but rarely dangerous. The situation changes if you develop a fever, swelling that spreads into your jaw, cheek, or under your eye, difficulty opening your mouth, or trouble swallowing. These are signs that an infection may be spreading beyond the tooth into deeper tissues. Facial swelling that worsens over hours, especially combined with fever or a general feeling of being unwell, needs same-day medical attention. A dental abscess left untreated can spread to the airway or bloodstream.
Even without emergency symptoms, a toothache that lasts more than a day or two usually means something structural is wrong: a cavity reaching the nerve, a cracked tooth, or an infection forming at the root. OTC medications manage the pain, but they don’t fix the underlying problem. The pain will keep coming back until the cause is treated.
