The fastest way to ease a toothache at home is to take an anti-inflammatory pain reliever like ibuprofen (400 mg) and rinse with warm saltwater. These two steps handle the majority of tooth pain in the short term, but they’re buying you time, not solving the problem. What you do next depends on the type of pain you’re experiencing and how serious the underlying cause turns out to be.
Quick Pain Relief at Home
The American Dental Association recommends ibuprofen (400 mg) as first-line treatment for toothache pain. For stronger relief, you can combine ibuprofen (400 mg) with acetaminophen (500 mg), taken together. This combination works better than either drug alone because the two target pain through different pathways. If you can’t take ibuprofen or other anti-inflammatory medications due to stomach issues, kidney problems, or other health conditions, acetaminophen on its own (1,000 mg) is the backup option.
While the pain reliever kicks in, mix half a teaspoon of salt into a glass of warm water and gently swish it around your mouth. This draws fluid out of inflamed tissue and helps keep the area clean. You can repeat the rinse several times a day. A cold compress, applied to the outside of your cheek in 15-minute intervals, also helps reduce swelling and temporarily numbs the area.
Clove oil is a well-known natural remedy, and it does have real numbing properties. The active compound makes up 70% to 90% of the oil and works as a local anesthetic and anti-inflammatory. Dab a tiny amount onto a cotton ball and hold it against the painful tooth. However, clove oil is toxic to human cells with repeated use and can irritate or damage your gums and the soft tissue inside your mouth, so treat it as a short-term fix, not a daily habit.
You can also apply a small, pea-sized amount of over-the-counter topical benzocaine gel directly to the painful area for localized numbing. Don’t swallow it, and limit yourself to four applications.
Why Toothaches Get Worse at Night
If your tooth pain seems manageable during the day but unbearable at bedtime, you’re not imagining it. When you lie flat, blood flow to your head increases, which puts extra pressure on the inflamed tissue around your tooth. Prop your head up with an extra pillow or two to counteract this. Keeping your head elevated above your heart reduces that pressure and can make the difference between a miserable night and a tolerable one.
What Your Pain Is Telling You
The type of pain you feel offers real clues about what’s going on inside the tooth. A sharp, stabbing pain when you bite down or touch a specific spot usually points to a cavity, a crack, or a problem with an existing filling or crown. This kind of pain is often triggered by contact and goes away quickly once the trigger stops.
A dull, persistent ache that lingers in the background could mean the tooth is infected. It can also be a sign that you grind your teeth during sleep, which puts chronic stress on the tooth and surrounding bone.
Severe, throbbing pain that pulses with your heartbeat is more concerning. This typically means infection has reached the pulp, the soft inner core of the tooth where the nerves and blood vessels live. This type of pain rarely resolves on its own and usually requires professional treatment soon.
Sensitivity to hot or cold drinks can indicate cavities, cracks, or gum disease. Brief sensitivity that fades in a few seconds is common and less worrying. Sensitivity that lingers for 30 seconds or more after the hot or cold source is removed suggests deeper involvement.
Signs You Need an ER, Not a Dentist
Most toothaches need a dentist, not an emergency room. But there are specific situations where the infection has progressed beyond a dental issue into a medical emergency. Go to an emergency room if you have a fever combined with visible swelling in your face, especially if you can’t reach your dentist. Difficulty breathing or swallowing is the most urgent red flag. These symptoms indicate the infection may have spread from the tooth into your jaw, throat, neck, or beyond.
What a Dentist Will Actually Do
Your dentist will take X-rays and assess your symptoms to figure out how far the damage has gone. The treatment path depends almost entirely on depth.
If decay is limited to the outer layers of the tooth (the hard enamel and the layer beneath it called dentin), a filling is usually all you need. Fillings are quick, minimally invasive, and typically done in a single short visit. They work well when the inner pulp hasn’t been affected and there’s no infection.
If decay or trauma has reached the pulp, a filling won’t cut it. A root canal removes the infected pulp tissue, cleans the inside of the tooth, and seals it. The tooth is preserved but is no longer “alive” in the traditional sense. Despite its reputation, modern root canal treatment is comparable to getting a filling in terms of discomfort. Most people return to normal activities the next day.
If the damage is too extensive for even a root canal, or if the tooth has fractured below the gumline, extraction becomes the remaining option. Untreated pulp infections don’t just cause pain. They can lead to abscesses, bone loss in the jaw, and eventually the loss of the tooth anyway, so delaying treatment generally narrows your options rather than expanding them.
If a Tooth Gets Knocked Out
A knocked-out permanent tooth is a true dental emergency with a narrow window for saving it. Handle the tooth only by the crown (the white part you normally see). Never touch the root, scrub the tooth, or wrap it in tissue, as all of these damage the delicate cells on the root surface that allow reattachment.
If the tooth is dirty, rinse it briefly with milk or your own saliva. Don’t use tap water, because the minerals in it can kill root surface cells. Try to place the tooth back into the socket yourself, then bite down gently on gauze or a damp napkin to hold it in place. If you can’t reinsert it, drop it into a small container of milk or saliva and get to a dentist or emergency room as fast as possible.
This protocol applies only to permanent teeth. Baby teeth that get knocked out are not reimplanted.
