A broken tooth can cause anything from a dull ache to severe, throbbing pain, and the fastest way to get relief at home is a combination of over-the-counter pain relievers, cold compresses, and protecting the exposed area. These steps buy you time, but a broken tooth always needs professional dental care to prevent infection and save the tooth.
Take the Right Pain Relievers
The American Dental Association recommends combining ibuprofen and acetaminophen for acute dental pain. This combination works better than either drug alone because they reduce pain through different pathways. Take 400 mg of ibuprofen (two standard pills) along with 500 mg of acetaminophen (one extra-strength pill). You can repeat this combination every six hours as needed.
Ibuprofen does double duty here: it blocks pain signals and reduces inflammation around the break. If you can only take one, ibuprofen is generally the stronger choice for tooth pain. Avoid aspirin, which can thin your blood and increase bleeding if the break has damaged your gums.
Protect the Broken Area
If the break has exposed the inner pulp of the tooth (the soft tissue containing the nerve), you can cover it with temporary filling material sold at most drugstores. These kits contain a putty-like material you press over the damaged area to seal it from air, food, and bacteria. This alone can dramatically reduce sensitivity.
If you don’t have temporary filling material, sugar-free gum or dental wax can work as a short-term barrier, especially if a sharp edge is cutting into your tongue or cheek. The goal is to keep the exposed surface covered until you can see a dentist.
Rinse, Ice, and Eat Carefully
Rinse your mouth with warm salt water after every meal. Mix half a teaspoon of salt into a cup of warm water and swish gently for 30 seconds. Salt water reduces bacteria around the break and helps keep the area clean without irritating it the way mouthwash can.
For swelling, hold ice or a cold cloth against your cheek near the broken tooth for 15 to 20 minutes at a time. One important exception: if the nerve is exposed (you’ll know because the pain is sharp, constant, and reacts intensely to temperature), avoid putting anything very hot or cold directly on the tooth. Stick to the outside of your cheek instead.
Switch to soft foods and avoid anything salty, spicy, or acidic. Citrus fruits, tomatoes, and vinegar-based dressings can sting badly on exposed tooth tissue. Chew on the opposite side of your mouth.
Be Cautious With Clove Oil
Clove oil is a popular home remedy for toothaches because it contains a natural numbing compound. In small amounts applied with a cotton ball, it can temporarily dull pain. But it comes with real risks, especially on a broken tooth. In higher concentrations, the active compound is cytotoxic, meaning it can damage living tissue. There are documented cases of painful gum ulcers developing days to weeks after clove oil application, particularly when it contacts exposed inner tooth tissue. If you use it at all, apply a tiny amount to a cotton ball and dab it on the gum near the tooth rather than directly on the break.
How to Tell if the Nerve Is Exposed
Not all broken teeth hurt the same way. A small chip on the outer enamel might cause no pain at all or just mild sensitivity. But when the break reaches the nerve, the symptoms are distinct and hard to ignore:
- Sharp, throbbing pain that radiates into your jaw, ear, or the side of your face
- Extreme sensitivity to hot and cold, where even a sip of room-temperature water triggers a jolt
- Spontaneous pain that flares up without any trigger
- Pain when biting down, even on soft food
If you look at the tooth and see a pinkish or reddish spot at the center of the break, that’s the pulp. It confirms nerve exposure and means you need dental care soon, not eventually.
What a Dentist Will Do
Treatment depends on how deep the break goes. A minor chip that only affects the outer enamel can often be smoothed or repaired with bonding (a tooth-colored resin applied in a single visit). A larger break that reaches the inner layer but hasn’t exposed the nerve typically needs a crown to rebuild the tooth’s structure.
When the nerve is exposed or damaged, a root canal is usually necessary. This removes the damaged nerve tissue, eliminates pain at its source, and saves the tooth. A crown goes on top afterward. If the tooth is cracked vertically down to the root, extraction may be the only option, followed by an implant or bridge.
What Happens if You Wait Too Long
A broken tooth is an open door for bacteria. When a fracture or chip creates a pathway to the inner pulp, bacteria can reach and infect the nerve much faster than they would through gradual decay. An untreated infection develops into a dental abscess, a pocket of pus that forms at the root of the tooth.
The warning signs of an abscess include pain that won’t go away even with medication, swollen gums, swollen lymph nodes in the neck, fever, and persistent bad breath. Once an abscess forms, it doesn’t resolve on its own. Left untreated for weeks or months, the infection can spread to the jaw, neck, and in rare but serious cases, the brain. At that stage, the situation becomes life-threatening.
A broken tooth that isn’t causing much pain right now can still be progressing toward infection. The absence of pain doesn’t mean the tooth is fine. It sometimes means the nerve has already died.
Signs You Need Emergency Care Now
Most broken teeth can wait a day or two for a dental appointment, but some situations call for immediate care. Go to an emergency room if bleeding from the break doesn’t stop after 15 minutes of firm pressure with gauze, if you develop a fever alongside tooth pain, or if swelling spreads from your gum to your face, jaw, or neck. Difficulty swallowing or breathing alongside a dental injury is a medical emergency. These signs suggest the infection has moved beyond the tooth itself.
