A broken tooth can often be fully repaired, but the right fix depends on how much of the tooth is damaged and whether the break reaches the inner nerve. Small chips may need nothing more than a single office visit for bonding, while deeper fractures can require a crown or root canal. Whatever the severity, acting quickly protects the tooth from infection and gives you the best chance of saving it.
What to Do Right Away
If a piece of your tooth has broken off, handle the fragment by its top surface only and avoid touching the root. Gently rinse it with cow’s milk or your own saliva, not tap water, which can damage the cells on the root surface that help with reattachment. Don’t wrap the fragment in tissue or cloth, and don’t scrub off any blood or debris. Place it in a small container of milk or saliva and bring it to your dentist.
While you wait for your appointment, rinse your mouth with warm salt water to keep the area clean. If there’s bleeding, press a piece of gauze against the spot. A cold compress on the outside of your cheek, 20 minutes on and 20 minutes off, helps control swelling. For pain, the American Dental Association recommends combining 400 mg of ibuprofen (two standard pills) with 500 mg of acetaminophen (one extra-strength pill). Take both together with water and a bit of soft food. This combination works better than either medication alone and is effective enough that many dental professionals now recommend it over prescription painkillers.
Small Chips: Bonding and Filling
For minor chips or small fractures that don’t reach the nerve, dental bonding is the simplest and least expensive repair. Your dentist roughens the surface of the tooth with a conditioning liquid, then applies a tooth-colored composite resin and shapes it to match your natural tooth. A special curing light hardens the resin in seconds. The entire process typically takes 30 to 60 minutes per tooth and usually requires no anesthesia.
Bonding materials last between 3 and 10 years, depending on where the tooth is and how much stress it takes from chewing. Front teeth that don’t bear heavy bite force tend to hold up longer. Over time the resin can stain or chip, at which point it can be patched or replaced in another quick visit. For slightly larger breaks on back teeth, a standard filling serves the same purpose and follows a similar process.
Larger Breaks: Crowns and Veneers
When a significant portion of the tooth is missing, bonding alone won’t provide enough structural support. A crown is a cap that covers and strengthens the entire remaining tooth. Your dentist removes enough of the outer surface to make room for the crown, takes an impression or digital scan, and fits a temporary crown while the permanent one is made. Some offices have same-day milling technology that skips the temporary altogether. Porcelain and ceramic crowns range from roughly $800 to $3,000 per tooth, depending on the material, location, and your dentist’s pricing.
Veneers are a thinner alternative that cover only the front surface of a tooth. They work well for cracked or chipped front teeth where the damage is mostly cosmetic. Placing a veneer requires shaving off only about half a millimeter of enamel, compared to the more significant reshaping needed for a crown. However, if the crack is deep, if the tooth already has a large filling, or if decay has set in around the break, a crown is the stronger and more protective choice.
Deep Fractures: When You Need a Root Canal
A crack that extends into the pulp, the soft tissue inside the tooth containing nerves and blood vessels, creates an opening for bacteria. You may notice sharp pain when chewing, lingering sensitivity to hot or cold, or a dull ache that doesn’t go away. Some deep cracks, especially vertical fractures that start below the gum line, cause no symptoms at all until an infection develops.
In these cases, a root canal removes the infected or damaged pulp, cleans the interior of the tooth, and seals it. After a root canal, the tooth is structurally weakened and almost always needs a crown on top to prevent further cracking. The procedure itself is done under local anesthesia and feels similar to getting a deep filling. Most people experience mild soreness for a few days afterward.
When the Tooth Can’t Be Saved
Some breaks are too severe for repair. A tooth that has split vertically all the way through the root, or one with a fracture deep below the gum line, often needs to be extracted. After extraction, the most common replacement options are a dental implant (a titanium post placed in the jawbone with a crown on top), a fixed bridge anchored to neighboring teeth, or a removable partial denture. Implants look and function the most like natural teeth but involve a surgical placement and several months of healing before the final crown is attached.
What Happens If You Wait Too Long
A broken tooth that feels fine can still be a problem. Even a small crack exposes the inner layers of the tooth to bacteria in your mouth. An abscess, a pocket of infection at the root, can take several months to develop, and you may not feel it forming until swelling, persistent pain, or fever appears. Left untreated for weeks or months beyond that point, the infection can spread to the jaw, neck, or other areas of the body. People with diabetes, weakened immune systems, or poor nutrition face higher risk of these complications. The bottom line: a painless break still needs professional evaluation.
Recovery After a Repair
What recovery looks like depends on the procedure. Bonding requires no downtime at all. After a crown, mild sensitivity and soreness are normal and typically fade within a few days. During that window, avoid very hard or crunchy foods like nuts and crusty bread, as well as sticky foods like caramel or taffy that can pull at the crown. Stick to softer foods, chew on the opposite side, and keep up your normal brushing and flossing routine.
After a root canal, expect tenderness around the tooth for two to three days. The ibuprofen and acetaminophen combination described earlier works well for post-procedure pain too. Your dentist will schedule a follow-up to place the permanent crown, and until that appointment, be especially careful not to bite down hard on the treated tooth.
Costs and Insurance Coverage
Dental bonding is the most affordable option, generally running $100 to $500 per tooth depending on the extent of the repair. Crowns fall in the $800 to $3,000 range. Root canals add another $500 to $1,500 on top of the crown cost, depending on whether the tooth is a front tooth or a molar. Implants are the most expensive single-tooth replacement, often $3,000 to $5,000 or more for the full process.
Most dental insurance plans cover a portion of crowns and root canals, often 50% after your deductible, though coverage varies widely. Bonding for purely cosmetic chips may not be covered. If you don’t have insurance, many dental offices offer payment plans, and dental schools provide supervised care at reduced rates. Getting an estimate before the procedure helps you plan, and it’s reasonable to ask your dentist’s office for one.
