Naproxen is one of the more effective over-the-counter options for toothache pain. The American Dental Association recommends NSAIDs like naproxen as first-line treatment for acute dental pain, whether you’re dealing with a toothache or recovering from a tooth extraction. It works well because toothaches involve significant inflammation, and naproxen targets that inflammation directly.
Why Naproxen Works Well for Tooth Pain
Toothache pain is largely driven by inflammation. When a tooth is damaged, decayed, or infected, your body produces chemical messengers called prostaglandins that sensitize nerve endings and trigger swelling. Naproxen blocks the enzymes responsible for making those prostaglandins, which reduces both pain and the inflammation fueling it.
This gives naproxen an edge over acetaminophen (Tylenol) for dental pain specifically. In a clinical trial comparing the two after dental implant surgery, patients taking naproxen reported significantly lower maximum pain scores (a median of 1 on a 10-point scale) compared to those taking acetaminophen (a median of 3). Naproxen also did a better job suppressing inflammatory markers in the blood. Acetaminophen can reduce pain, but it doesn’t tackle the inflammation component nearly as effectively.
How Long Relief Lasts
One of naproxen’s biggest advantages for toothaches is its duration. A single dose provides up to 7 hours of pain relief, and in some cases closer to 12. That’s roughly twice as long as ibuprofen, which typically wears off in 4 to 6 hours. If your toothache is disrupting sleep, naproxen’s longer action means you’re less likely to wake up in pain at 3 a.m.
Over-the-counter naproxen sodium (sold as Aleve) comes in 220 mg tablets. The standard dosing for adults and children 12 and older is one tablet every 8 to 12 hours. For your first dose, you can take two tablets within the first hour. After that, don’t exceed two tablets in any 8 to 12 hour window or three tablets in 24 hours.
Combining Naproxen With Acetaminophen
For more severe toothaches, you can take naproxen and acetaminophen together. Because these two drugs work through completely different pathways, combining them blocks pain signals at multiple points simultaneously. The ADA notes this combination is “highly effective” for mild to moderate dental pain, and the side effect profile isn’t meaningfully worse than taking either drug alone.
You should not, however, combine naproxen with ibuprofen or aspirin. These are all NSAIDs and work through the same mechanism, so stacking them increases the risk of side effects without adding much benefit.
How Naproxen Compares to Ibuprofen
Both naproxen and ibuprofen are NSAIDs, and both are effective for dental pain. The ADA guidelines mention them interchangeably as first-line options. The practical difference comes down to convenience: naproxen lasts longer, so you take it less often. Ibuprofen kicks in slightly faster for some people and allows more flexible dosing since you can take it every 6 hours. If your toothache is steady and persistent, naproxen’s longer duration is the more practical choice. If you need quick relief and plan to re-dose as needed, ibuprofen works just as well.
Side Effects to Watch For
The most common side effects of naproxen are stomach-related: heartburn, nausea, and abdominal pain, reported in roughly 3% to 9% of users in clinical trials. Headache, dizziness, and drowsiness occur at similar rates. Taking naproxen with food can reduce stomach irritation.
For short-term use (a few days while waiting for a dental appointment), serious side effects are uncommon in otherwise healthy adults. The risks go up with longer use. NSAIDs can cause gastrointestinal bleeding, and people with a history of stomach ulcers or GI bleeding are at more than 10 times the risk compared to those without that history. Smoking, alcohol use, older age, and taking blood thinners or corticosteroids also increase this risk.
Naproxen is not a good choice if you have significant kidney disease, severe heart failure, or a recent history of heart attack or stroke. NSAIDs as a class can worsen kidney function and raise cardiovascular risk, so people with these conditions should use acetaminophen instead or talk to their doctor about alternatives.
Signs Your Toothache Needs More Than Pain Relief
Naproxen can manage toothache pain temporarily, but it doesn’t treat the underlying cause. Certain symptoms signal that something more serious is going on and that you need dental care sooner rather than later:
- Facial or jaw swelling, which often indicates an abscess or spreading infection
- Fever or chills, a sign your body is fighting a significant infection
- Pus or bleeding around the affected tooth
- Numbness in your jaw or around the tooth, which can mean nerve damage or advanced infection
- A persistent foul taste or smell, suggesting an abscess may be draining
- A loose adult tooth
Pain so severe that it keeps you awake or prevents you from functioning during the day also warrants urgent attention, even without the other warning signs. Naproxen can bridge the gap until you get into a dental office, but it’s managing symptoms while the underlying problem, whether that’s a cavity, crack, or infection, continues.
