The fastest relief for a toothache comes from combining ibuprofen and acetaminophen, which outperforms either drug alone. But pain medication is only buying you time. A toothache signals damage or infection inside the tooth, and the underlying cause needs professional treatment. Here’s what works best while you wait.
The Most Effective Pain Relief Combination
Anti-inflammatory painkillers are the first-line treatment for toothache, not opioids. The American Dental Association’s clinical practice guideline specifically recommends nonsteroidal anti-inflammatory drugs (like ibuprofen) alone or combined with acetaminophen as the go-to approach for acute dental pain, noting they provide superior relief with fewer side effects than opioid painkillers.
A randomized clinical trial testing this combination after wisdom tooth removal found that taking acetaminophen and ibuprofen together provided significantly greater and faster pain relief than either medication on its own. The combination beat each individual drug on nearly every measure: time to meaningful relief, peak pain reduction, and how long patients could go before needing additional medication.
For adults, a common approach is 400 to 600 mg of ibuprofen alongside 500 mg of acetaminophen, taken every six hours. These two drugs work through different mechanisms, so they complement each other rather than doubling up on the same pathway. Ibuprofen reduces inflammation at the source of pain, while acetaminophen works on pain signaling in the brain. Do not exceed 4,000 mg of acetaminophen in a 24-hour period, as higher amounts can cause liver damage. If you drink alcohol regularly, your safe limit is lower.
Salt Water Rinse
A warm salt water rinse is the simplest thing you can do right now. Mix 1 teaspoon of salt into 8 ounces of warm water until dissolved, then swish it around the painful area for 15 to 30 seconds before spitting it out. If it stings too much, cut back to half a teaspoon. You can repeat this up to four times a day and after meals.
Salt water pulls fluid out of inflamed gum tissue through osmosis, which temporarily reduces swelling. It also creates an environment that’s harder for bacteria to thrive in. This won’t fix anything, but it can take the edge off and help keep the area cleaner while you arrange dental care.
Hydrogen Peroxide Rinse
A diluted hydrogen peroxide rinse can help reduce bacteria and inflammation around an infected tooth. Mix equal parts 3% hydrogen peroxide (the standard concentration sold at pharmacies) with water, swish gently for 30 seconds, and spit it all out. Do not swallow any of it. This is best used once or twice a day, not as a long-term habit, since frequent use can irritate your gums and disrupt the natural balance of bacteria in your mouth.
Cold Compress
Holding a cold pack or a bag of ice wrapped in a cloth against your cheek, near the painful tooth, can numb the area and reduce swelling. Apply it for 15 to 20 minutes at a time with breaks in between. Cold narrows the blood vessels in the area, which limits the amount of inflammatory fluid reaching the damaged tissue. This is especially useful if you have visible swelling along your jawline or cheek.
A Note on Numbing Gels
Over-the-counter oral numbing gels containing benzocaine are widely sold, but they come with real limitations. Saliva washes the gel away quickly, so relief tends to last only a few minutes. More importantly, the FDA has warned that benzocaine can cause a rare but serious condition called methemoglobinemia, which drastically reduces the blood’s ability to carry oxygen. This risk is highest in young children, and benzocaine products should not be used for teething pain in infants or toddlers at all. For adults, these gels are generally safe for very short-term, occasional use, but ibuprofen and acetaminophen will do more for you.
Sleeping With a Toothache
Toothaches famously get worse at night, and there’s a straightforward reason. When you lie flat, blood flows more easily to your head, increasing pressure in already-inflamed tissue. The inside of a tooth is a rigid chamber that can’t expand. Even a small increase in blood volume creates noticeable pressure against the nerve.
Propping your head up with an extra pillow or two forces your heart to work against gravity to push blood upward, naturally lowering blood pressure in the head and neck. This small positional change can meaningfully reduce the throbbing. Taking your pain medication about 30 minutes before bed also helps you fall asleep before the next wave of pain builds.
What a Toothache Is Telling You
Pain that’s mild and comes only with hot or cold food might be sensitivity from a small cavity, a cracked filling, or receding gums. Sharp pain when you bite down often points to a crack in the tooth or a deep cavity. A constant, throbbing ache, especially one that wakes you up at night, typically means the nerve inside the tooth is inflamed or infected. This type of pain rarely resolves on its own and usually needs a root canal or extraction.
If the pain has been building over days and you notice a swollen bump on your gum near the painful tooth, that’s likely an abscess, a pocket of infection. Abscesses can sometimes drain on their own temporarily, giving the illusion that things are improving, but the infection is still there.
Signs You Need Emergency Care
Most toothaches can wait for a dental appointment within a few days. But certain symptoms mean the infection has spread beyond the tooth, and that requires urgent medical attention. Go to an emergency room if you have facial swelling combined with a fever, difficulty breathing, or trouble swallowing. These signs suggest the infection is moving into your jaw, throat, or neck. A dental infection that reaches the airway or bloodstream can become life-threatening quickly. If you can’t reach your dentist and you have a fever with facial swelling, don’t wait it out.
