A toothache rarely resolves on its own, but you can significantly reduce the pain while you arrange to see a dentist. The fastest at-home relief comes from combining two common over-the-counter pain relievers, and several other simple techniques can help bridge the gap until professional treatment. Here’s what actually works, why it works, and what to do next.
Why Your Tooth Hurts
Understanding the source of the pain helps you treat it more effectively. Most toothaches fall into two categories: sensitivity and infection. Sensitivity pain happens when tiny fluid-filled tubes inside your tooth react to temperature or pressure. Cold drinks, for example, cause fluid inside these tubes to shift outward, triggering nerve fibers near the surface. That’s why cold tends to produce a sharp, immediate sting.
Deeper, throbbing pain that lingers usually signals inflammation of the pulp, the soft tissue inside the tooth that contains nerves and blood vessels. When bacteria reach the pulp through a cavity or crack, the immune response causes swelling. But because the pulp is trapped inside a rigid shell of hard tooth, that swelling has nowhere to go. Pressure builds against the nerve fibers, producing the persistent, dull ache that can keep you up at night. Left untreated, the nerve can die and an abscess can form at the root.
Over-the-Counter Pain Relief That Works Best
The most effective option for dental pain is taking ibuprofen and acetaminophen together. These two drugs work through completely different pathways: ibuprofen reduces inflammation at the source, while acetaminophen blunts pain signaling in the brain. Combined, they outperform either drug alone and rival some prescription painkillers for dental pain. A combination tablet is available over the counter containing 125 mg ibuprofen and 250 mg acetaminophen per tablet, dosed at two tablets every eight hours for adults and children 12 and older, with a maximum of six tablets per day.
If you’re using separate bottles, the standard adult approach is 200 to 400 mg of ibuprofen alongside 500 mg of acetaminophen. Take ibuprofen with food to protect your stomach, and don’t exceed the daily limits listed on each package. Avoid aspirin if there’s any chance the tooth will need extraction soon, since aspirin thins the blood and can increase bleeding.
Saltwater Rinse
A warm saltwater rinse is one of the simplest and safest things you can do right now. Dissolve 1 teaspoon of table salt in 8 ounces of warm water, swish it gently around the painful area for about 30 seconds, then spit it out. The salt draws fluid out of swollen tissue through osmosis, which can temporarily reduce pressure and pain. It also creates a less hospitable environment for bacteria. Research supports concentrations in the range of 0.9% to 1.8% salt for promoting gum health and recovery, which is roughly what 1 teaspoon in 8 ounces gives you. If it stings too much, cut the salt to half a teaspoon. You can repeat this several times a day.
Cold Compress for Swelling
If you notice swelling in your cheek or jaw, hold an ice pack or bag of frozen vegetables against the outside of your face for 10 to 20 minutes at a time, with a thin cloth between the ice and your skin. Cold constricts blood vessels, which slows the flow of inflammatory fluid to the area and numbs the nerve signals. Take at least a 20-minute break between applications to avoid skin damage. This won’t fix the underlying problem, but it can meaningfully reduce both swelling and pain, especially in the first day or two.
Topical Numbing Gels and Clove Oil
Over-the-counter oral gels containing benzocaine can numb the area around a painful tooth for short-term relief. Apply a small amount directly to the gum near the affected tooth. One important safety note: the FDA has warned that benzocaine can cause a rare but serious condition that reduces oxygen levels in the blood. These products should never be used on children under 2 years old, and products for older children and adults should carry specific warnings on the label. Follow the directions closely and don’t overuse them.
Clove oil is a traditional remedy that contains eugenol, a natural compound with mild numbing and anti-inflammatory properties. You can dab a tiny amount onto a cotton ball and hold it against the sore tooth. Use it sparingly. Eugenol in larger quantities can burn the soft tissue of your mouth and throat, so a drop or two is enough. It tastes strong and medicinal, but many people find it takes the edge off while waiting for other pain relief to kick in.
What Not to Do
Avoid placing aspirin directly on the gum tissue. This is an old folk remedy that causes chemical burns without providing meaningful pain relief. Similarly, don’t apply heat to a swollen jaw. Heat increases blood flow and can worsen swelling, especially if an infection is present. Skip extremely hot or cold foods and drinks if temperature triggers your pain, and try chewing on the opposite side of your mouth. If the pain is keeping you from sleeping, elevate your head with an extra pillow to reduce blood pressure in the area.
Why You Still Need a Dentist
Everything above is a temporary measure. A toothache caused by decay, a crack, or infection will not heal on its own, and delaying treatment generally makes the problem worse and more expensive to fix. The two most common professional treatments for a tooth with damaged or infected pulp are root canal therapy and extraction. A root canal removes the diseased tissue from inside the tooth, cleans and disinfects the internal chamber, then seals it. This saves the natural tooth structure and eliminates the pain. An extraction removes the tooth entirely. Your dentist will recommend one or the other based on how much healthy tooth remains and whether the infection has spread.
For less severe problems, a simple filling, a crown, or treating gum disease around the tooth may be all that’s needed. Many people find their pain disappears entirely the same day as treatment.
Signs You Need Emergency Care
Most toothaches can wait a day or two for a dental appointment, but certain symptoms signal a spreading infection that requires immediate attention. Go to an emergency room if you have a fever combined with facial swelling, or if you’re having trouble breathing or swallowing. These can indicate that an abscess is spreading beyond the tooth into deeper tissues of the head and neck, which is a medical emergency. If you can’t reach your dentist and you have fever plus facial swelling, don’t wait.
