Aleve works well for toothaches. Its active ingredient, naproxen sodium, reduces both pain and inflammation, which makes it particularly effective for dental pain where swelling around the tooth or gum is part of the problem. In clinical trials, a single dose provided significant pain relief starting within 15 minutes and lasting up to 12 hours, considerably longer than most over-the-counter pain relievers.
Why Aleve Works for Tooth Pain
Toothaches typically involve inflammation. Whether the cause is a cavity, a cracked tooth, or an infection, the tissue around the affected area produces chemical signals called prostaglandins that increase blood vessel permeability, cause swelling, and amplify pain. Naproxen sodium blocks the enzyme responsible for producing these prostaglandins, which means it doesn’t just mask the pain. It actively reduces the swelling and inflammation driving it.
This two-pronged effect (pain relief plus anti-inflammatory action) is why dentists frequently recommend NSAIDs like Aleve over acetaminophen (Tylenol) for dental pain. Acetaminophen can lower pain signals but does little for inflammation itself.
How It Compares to Ibuprofen
Ibuprofen (Advil, Motrin) is the other common NSAID people reach for during a toothache. In a head-to-head study of patients with pain after wisdom tooth extraction, naproxen sodium and ibuprofen were comparable in how quickly they started working. The key difference showed up later: naproxen sodium trended toward better pain control from 1 to 12 hours, with the advantage reaching statistical significance at the 12-hour mark.
The practical takeaway is straightforward. Ibuprofen at standard OTC doses needs to be taken every 4 to 6 hours. Aleve lasts 8 to 12 hours per dose, so you get sustained relief with fewer pills. If your toothache is keeping you up at night, that longer duration means you’re less likely to wake up in pain at 3 a.m. needing another dose.
Dosing for Dental Pain
Each OTC Aleve tablet contains 220 mg of naproxen sodium. The label directions for adults and children 12 and older are:
- First dose: You can take 2 tablets (440 mg) within the first hour
- Ongoing doses: 1 tablet every 8 to 12 hours while symptoms last
- Maximum: No more than 2 tablets in any 8- to 12-hour window, and no more than 3 tablets in 24 hours
Take each dose with a full glass of water, ideally with food to reduce the chance of stomach irritation. Using the lowest effective dose is always the goal, especially if you’re taking it for more than a day or two.
Who Should Avoid It
Aleve isn’t the right choice for everyone. The most significant risk factors for complications include:
- Blood thinners: Naproxen sodium can increase bleeding risk, and combining it with anticoagulant medications is generally discouraged.
- Older adults: People over 75 face a higher risk of gastrointestinal bleeding with NSAID use.
- Kidney problems: NSAIDs can stress the kidneys, particularly in people with existing kidney disease or dehydration.
- Stomach ulcers or GI bleeding history: NSAIDs can worsen these conditions.
If you’re scheduled for a dental extraction or oral surgery, mention your NSAID use to your dentist. While dental procedures aren’t classified as high bleeding risk surgeries, naproxen does affect platelet function, and your dentist may have specific timing recommendations.
Boosting Pain Relief With Acetaminophen
For moderate to severe toothaches, combining Aleve with acetaminophen (Tylenol) can provide stronger relief than either one alone. Because these two medications work through completely different mechanisms, they don’t compete with each other or increase each other’s side effects. You can take them at the same time or stagger them. Just follow the dosing limits for each medication independently, and don’t substitute ibuprofen for one of them since ibuprofen and naproxen are both NSAIDs and shouldn’t be taken together.
Signs Your Toothache Needs More Than Aleve
Aleve is a bridge, not a cure. It manages symptoms while you wait to see a dentist, but it won’t fix the underlying problem causing the pain. Certain symptoms signal that the situation is more urgent:
- Facial or jaw swelling: Visible swelling often indicates an abscess or spreading infection that can become dangerous if untreated.
- Fever or chills: Your body is fighting a bacterial infection that likely needs antibiotics.
- Bleeding or pus near the tooth: Discharge is a clear sign of active infection.
- Numbness: Loss of sensation in the area around a painful tooth can indicate nerve damage or an advanced infection.
- Pain so severe you can’t sleep or function: This level of pain often points to an exposed nerve, deep cavity, or abscess.
A persistent bad taste or foul smell in your mouth is another red flag, often caused by an abscess leaking pus or significant decay. Any of these symptoms warrant prompt dental care rather than continued self-treatment with OTC pain relievers.
