A broken tooth hurts because the protective outer layers have been compromised, exposing sensitive inner tissue to air, temperature, and pressure. The fastest way to soothe it is to cover any sharp or exposed areas with dental wax or temporary filling material (both available at drugstores), take an over-the-counter pain reliever, and avoid chewing on that side until you can get to a dentist.
What you need to do right now depends on how deep the break goes and whether the nerve is exposed. Here’s how to assess the damage and manage pain effectively at home.
Assess How Deep the Break Goes
Not all breaks are equal, and knowing what you’re dealing with helps you respond correctly. A small chip that only affects the outer enamel layer usually doesn’t hurt much. The tooth looks slightly uneven, and the main concern is the sharp edge cutting your tongue or cheek. Sensitivity tests and mobility are typically normal with this type of fracture.
A deeper break that reaches the second layer, called dentin, feels more sensitive but still doesn’t expose the nerve. The tooth stays alive and functional, though you’ll likely notice discomfort when eating or drinking.
The most painful scenario is when the break exposes the pulp, the soft tissue inside the tooth that contains the nerve. You’ll know this has happened because the tooth becomes intensely sensitive to air, temperature, and any pressure. You may see a pinkish or reddish spot at the center of the broken surface. If the nerve is exposed, avoid putting anything very hot or cold directly on the tooth until a dentist can treat it.
Cover Sharp Edges Right Away
A broken tooth often leaves razor-sharp edges that slice into your tongue, cheek, or gums every time you talk or swallow. Dental wax, the same product used for braces, works well as a temporary shield. Take a pea-sized piece, roll it into a ball with clean hands, flatten it into a small disc, and press it firmly over the sharp area. If it peels off, just apply more. Replace it after eating.
For a larger break where deeper tooth structure is exposed, temporary filling material is a better option. These kits are sold at most pharmacies and come with simple instructions. The material forms a more durable barrier than wax and can protect exposed dentin or pulp until your dental appointment.
Manage the Pain
For mild to moderate dental pain, ibuprofen at 400 mg is the most effective single option because it reduces both pain and inflammation. Acetaminophen at 1,000 mg is an alternative if you can’t take ibuprofen. The strongest approach without a prescription is combining the two, since they work through different mechanisms and together provide more relief than either one alone. Take them on a regular schedule rather than waiting for pain to return.
Applying ice or a cold cloth to the outside of your cheek near the broken tooth helps reduce swelling. You can also suck on a small piece of ice, but only if the nerve isn’t exposed. If cold triggers a sharp, shooting pain, stop immediately.
Clove Oil for Localized Numbness
Clove oil contains a natural numbing compound that has been used for dental pain for centuries. To use it safely, dilute a few drops into a carrier oil like coconut or olive oil, then dab it onto the affected area with a cotton swab. Don’t swallow it. Keep in mind that clove oil is meant for occasional, short-term use only. Repeated application can irritate gums and soft tissue, and it should not be applied directly to exposed pulp. Pregnant or breastfeeding people should avoid it entirely.
Rinse With Salt Water After Meals
A warm saltwater rinse helps keep the broken area clean and reduces the risk of infection. Mix one teaspoon of salt into eight ounces (one cup) of warm water. Swish gently around the broken tooth after every meal. If your mouth is very tender, cut the salt to half a teaspoon for the first day or two. This isn’t a substitute for brushing, but it reaches areas around the fracture that a toothbrush might irritate.
Protect the Tooth While Eating
A fractured tooth is weaker than it was, more sensitive to temperature, and vulnerable to infection. What you eat in the days before your dental visit matters.
- Avoid hard foods like nuts, chips, raw carrots, and apples. Even healthy crunchy foods can crack the tooth further.
- Skip sticky foods like caramel, toffee, and gum, which can pull on the broken piece or dislodge temporary filling material.
- Stay away from acidic drinks like soda and citrus juice, which irritate exposed dentin.
- Keep food and drinks lukewarm. Very hot or icy temperatures trigger nerve pain in a compromised tooth.
Chew on the opposite side of your mouth. Soft foods like yogurt, scrambled eggs, mashed potatoes, and soup at a comfortable temperature are your safest options.
Warning Signs That Need Urgent Attention
Most broken teeth can wait a day or two for a dental appointment, but certain symptoms signal a spreading infection that needs immediate care. A fever combined with swelling in your face, cheek, or neck suggests the break has led to an abscess. If swelling makes it difficult to breathe or swallow, go to an emergency room. These signs indicate the infection may be moving into deeper tissues of the jaw, throat, or neck.
What a Dentist Will Do
The repair depends on how much tooth structure is lost and whether the nerve is involved. A small enamel chip can often be smoothed down or repaired with dental bonding, a tooth-colored resin applied in a single visit. Larger breaks that compromise the tooth’s structure typically need a crown, which fits over the remaining tooth like a cap. Same-day crowns start around $1,350.
If the fracture exposed the nerve, a root canal is usually necessary to remove the damaged nerve tissue before the tooth can be restored. Root canals range from roughly $960 for a front tooth to $1,185 for a molar. A crown is almost always placed afterward. For teeth with significant cosmetic damage, particularly front teeth, porcelain veneers ($1,600 to $2,000) are another option.
In the meantime, desensitizing toothpaste can help dull lingering sensitivity, especially if the break exposed dentin. You may need to try a few brands to find one that works well for you. Your dentist may also apply a fluoride treatment or dental sealant to strengthen and protect the exposed surface.
