Motrin is one of the best over-the-counter options for tooth pain. The American Dental Association recommends ibuprofen (the active ingredient in Motrin) as first-line therapy for both toothaches and pain after dental procedures like extractions. In a head-to-head clinical trial, 400 mg of ibuprofen outperformed 1,000 mg of acetaminophen (Tylenol), delivering stronger peak relief that lasted longer.
Why Motrin Works Well for Dental Pain
Tooth pain is usually driven by inflammation, whether from a cavity reaching the nerve, an infection at the root, or swollen gums. Motrin targets this directly. It blocks an enzyme at the site of tissue injury that produces inflammatory chemicals called prostaglandins. With fewer prostaglandins, the nerve endings in and around your tooth become less sensitized, so the pain signal weakens. Acetaminophen can reduce pain too, but it doesn’t fight inflammation the same way, which is why ibuprofen tends to perform better for dental-specific pain.
How Much to Take and When It Kicks In
The standard adult dose for tooth pain is 400 mg (two over-the-counter 200 mg tablets) every four to six hours as needed. The maximum daily limit is 2,400 mg. Relief typically begins within 30 to 60 minutes and lasts about six to eight hours per dose.
If you’ve just had a tooth pulled or dental surgery, take your first dose about an hour after the procedure, before the local anesthetic fully wears off. This gets ahead of the pain rather than chasing it. Take each dose with a full glass of water and some soft food to protect your stomach.
Combining Motrin With Tylenol for Stronger Relief
For moderate to severe tooth pain, the combination of ibuprofen and acetaminophen taken together works better than either one alone. The ADA specifically recommends this approach: 400 mg of ibuprofen plus 500 mg of acetaminophen. Because the two drugs reduce pain through completely different pathways, they amplify each other’s effects without increasing the dose of either one.
Clinical trials on patients recovering from wisdom tooth removal confirmed that ibuprofen/acetaminophen combinations provided pain relief comparable to higher doses of ibuprofen alone, meaning you get strong results at lower total drug exposure. You can repeat this combination every six hours. Just be careful not to exceed the daily maximum for each drug separately: 2,400 mg for ibuprofen and 4,000 mg for acetaminophen.
Who Should Avoid Motrin
Motrin isn’t safe for everyone. You should avoid it if you are pregnant, have a history of kidney or liver disease, have bleeding problems, or take blood thinners (including daily aspirin). People with a history of stomach ulcers are also at higher risk for side effects. The most common issue is an upset stomach, which taking it with food helps prevent. Don’t drink alcohol while using it.
Children under six months should not take ibuprofen at all. For older children, dosing is based on weight rather than age. Children’s Motrin liquid and chewable tablets come in clearly labeled concentrations. A child weighing 24 to 35 pounds, for example, would take one 100 mg chewable tablet or 5 mL of the liquid, while a child 96 pounds or heavier can take the standard adult dose of two 200 mg tablets.
What Motrin Can and Can’t Do
Motrin is effective at managing tooth pain, but it doesn’t treat the underlying cause. A cavity, cracked tooth, or abscess will continue to worsen regardless of how well you control the symptoms. Think of Motrin as a bridge to get you through until you can see a dentist, not a long-term solution.
There are also situations where Motrin won’t be enough. If the pain is so severe that maximum doses aren’t controlling it, or if you notice swelling spreading along your jaw, down into your neck, or causing difficulty breathing, that suggests a serious infection that needs professional treatment right away. Fever combined with tooth pain is another sign that over-the-counter relief alone isn’t sufficient.
