The best pain reliever for a toothache is ibuprofen, either alone or combined with acetaminophen. The American Dental Association recommends 400 mg of ibuprofen as a first-line treatment for acute dental pain, with the option to add 500 mg of acetaminophen for stronger relief. This non-opioid combination outperforms many prescription painkillers, including opioid formulations, with fewer side effects.
Why Ibuprofen Works Best for Tooth Pain
Toothaches are driven by inflammation. When a tooth is damaged, decayed, or infected, your body produces chemical signals called prostaglandins that trigger swelling and pain at the site. Ibuprofen and other anti-inflammatory drugs block the enzyme responsible for producing those signals, attacking the pain at its source rather than just masking it. That’s why they tend to work better for dental pain than acetaminophen alone, which reduces pain perception but doesn’t address the underlying inflammation.
Naproxen sodium (the active ingredient in Aleve) works through the same mechanism and is another solid option. The ADA suggests 440 mg of naproxen sodium as an alternative to ibuprofen. Naproxen lasts longer per dose, roughly 8 to 12 hours compared to ibuprofen’s 4 to 6, so it can be more convenient if you need overnight relief.
The Ibuprofen-Plus-Acetaminophen Strategy
Taking ibuprofen and acetaminophen together is more effective than taking either one alone. Multiple randomized controlled trials after tooth extractions have confirmed this, and the ADA now includes this combination in its clinical guidelines. The two drugs work through completely different pathways, so they complement each other without doubling the risk of side effects.
Here’s how to use this approach safely:
- Ibuprofen: 400 mg every 6 hours as needed. Do not exceed 1,200 mg per day for over-the-counter use.
- Acetaminophen: 500 mg alongside each ibuprofen dose, or alternating between the two every 3 hours. Never exceed 4,000 mg of acetaminophen in 24 hours.
You can take them at the same time or stagger them so you’re getting a dose of something every few hours. Staggering can help maintain more consistent pain control throughout the day.
If You Can’t Take Anti-Inflammatory Drugs
Not everyone can safely use ibuprofen or naproxen. You should avoid these drugs if you have kidney disease (especially with an eGFR below 60), liver disease, heart failure, high blood pressure, or if you’re taking blood pressure medications like ACE inhibitors or diuretics. Anti-inflammatory drugs reduce blood flow to the kidneys, which can cause acute kidney injury or worsen existing kidney problems.
In these cases, the ADA recommends acetaminophen alone at a full therapeutic dose of 1,000 mg. This is a higher dose than what most people take by default, and it provides meaningfully better pain relief than the standard 500 mg tablet. Acetaminophen is gentler on the kidneys and stomach, though people with liver disease should be cautious with it and may need a lower dose.
Topical Options for Immediate Relief
While you wait for an oral painkiller to kick in, topical numbing agents can take the edge off. Over-the-counter gels containing 20% benzocaine (sold as Orajel and similar brands) numb the tissue around the tooth within a few minutes. You apply a small amount directly to the gum near the painful area.
Clove oil is a natural alternative that performs just as well. A controlled study comparing clove gel to benzocaine gel found no significant difference in pain scores between the two, and both were significantly better than placebo. Clove oil contains a natural anesthetic compound that dentists have used for centuries. The tradeoff: both benzocaine and clove oil cause a mild burning sensation during application, and clove gel occasionally causes small mouth ulcers at the application site.
Salt water rinses are another simple tool. Dissolving half a teaspoon of salt in warm water and swishing gently for 30 seconds draws fluid out of swollen tissue, reduces bacterial load, and helps maintain an oral pH that discourages further bacterial growth. This won’t replace a painkiller, but it can reduce the inflammation feeding your pain and keep the area cleaner while you wait for dental treatment.
What to Avoid
Aspirin placed directly on the gum tissue is a common folk remedy that actually burns the soft tissue and can make things worse. Take aspirin orally if you’re going to use it at all, though ibuprofen is a better choice for dental pain.
Opioid painkillers are rarely appropriate for toothaches. The ADA explicitly recommends non-opioid options as first-line therapy, noting that the ibuprofen-acetaminophen combination provides greater pain relief with fewer adverse effects than many opioid-containing formulations. Opioids don’t target the inflammation causing your pain. They only alter how your brain perceives it, which makes them a poor match for this type of problem.
Signs Your Toothache Needs Urgent Care
Over-the-counter pain relief is a temporary measure. It manages symptoms while you arrange to see a dentist, but it doesn’t treat the cause. Some situations can’t wait for a routine appointment:
- Facial swelling in the cheek, jaw, or gums, especially if it’s spreading toward your neck or eye
- Fever or chills alongside tooth pain
- Pus or a foul taste in your mouth
- Difficulty swallowing or breathing
- Trouble opening your mouth fully
- Pain that wakes you from sleep and doesn’t respond to OTC medication
These signs point to a dental infection that may be spreading. A spreading infection in the head and neck can become dangerous quickly, particularly if swelling begins to compromise your airway. If you have difficulty swallowing or breathing, that warrants emergency care, not a dental office visit.
