A broken tooth can almost always be repaired, but what your dentist recommends depends entirely on how much of the tooth is damaged and whether the break has reached the inner nerve. Small chips may need nothing more than a single office visit. A tooth cracked down to the root might require extraction and replacement. The key variable is time: the sooner you get professional care, the more of your natural tooth can be saved.
What to Do Right Away
If a piece of your tooth has broken off, find the fragment if you can. Handle it only by the crown (the visible white part) and avoid touching the root. Don’t scrub it, wrap it in tissue, or rinse it under tap water. Too much tap water kills the cells on the root surface that help with reattachment. Instead, gently rinse the fragment with milk or your own saliva, then store it in a small container of milk or saliva until you can see a dentist.
If the entire tooth has been knocked out and the socket is clean, you can try placing it back in gently and biting down on a damp paper towel to hold it in place. If that’s not possible, keep it in milk and get to a dentist within an hour for the best chance of saving it.
For pain and swelling, rinse your mouth with warm salt water, apply a cold compress to your cheek in 10-minute intervals, and take an over-the-counter pain reliever. If the break has left a sharp edge cutting into your tongue or cheek, you can cover it with a small piece of sugar-free gum or dental wax as a temporary barrier.
Over-the-Counter Repair Kits
Pharmacies sell temporary tooth filling kits that use a soft cement you press into the damaged area. These are strictly a short-term bridge to a dental appointment, not a fix. The main risks are trapping bacteria under the material (which can cause infection), applying it incorrectly and damaging surrounding tissue, and the false sense of security that delays real treatment. Some filling materials also contain ingredients that can cause allergic reactions or are mildly toxic if swallowed.
If you use one, treat it as a protective cover for a day or two, not a solution. The longer a temporary filling stays in, the greater the chance of complications underneath it.
Small Chips: Dental Bonding
For minor chips that haven’t exposed the nerve, dental bonding is the simplest professional repair. Your dentist applies a tooth-colored composite resin directly to the damaged area, sculpts it to match the original shape, and hardens it with a curing light. The whole process takes about 30 to 60 minutes per tooth, typically requires no anesthesia, and you walk out with a tooth that looks normal.
Bonding material lasts between 3 and 10 years before it needs to be touched up or replaced. It’s not as strong as your natural enamel, so it works best on teeth that don’t bear heavy chewing force, like front teeth. Bonding is also one of the most affordable cosmetic dental procedures.
Moderate Breaks: Dental Crowns
When a tooth has lost a significant chunk of structure but the root is still healthy, a crown is the standard repair. A crown is essentially a custom-fitted cap that covers the entire visible portion of the tooth, restoring its shape and strength. The process usually takes two visits spread over a couple of weeks: one to prepare the tooth and take impressions, and another to cement the permanent crown.
The most common materials are zirconia, all-ceramic, and porcelain fused to metal (PFM). Zirconia is the strongest option. It resists chipping and cracking under normal biting forces, and modern versions look quite natural. It’s also biocompatible, meaning the smooth surface works well with gum tissue. PFM crowns cost less but can develop a visible gray line at the gumline over time as gums recede, and the metal underneath blocks light in a way that can look slightly artificial.
Without insurance, a dental crown costs between $800 and $2,500. Zirconia and all-ceramic crowns average around $1,300, while PFM crowns average about $1,100. If you have dental insurance, your plan typically covers about 50% of the cost for medically necessary crowns, though most plans cap annual coverage at $1,000 to $2,500.
Recovery After a Crown
If you receive a temporary crown while waiting for your permanent one, avoid chewing on that side of your mouth entirely. Once the permanent crown is bonded, it’s far more secure, but you should still take it easy for the first few days. Chew on the opposite side to let the cement fully set and your bite adjust. For the first couple of weeks, avoid hard foods like nuts, ice, and popcorn kernels, along with sticky foods like caramels, taffy, and gummy candy that can pull a crown loose. Tough meats, crusty bread, and raw carrots are also worth skipping during the initial healing phase. After that, you can return to a normal diet.
Deep Breaks: Root Canal Treatment
If the break extends deep enough to expose the pulp (the soft tissue inside your tooth containing nerves and blood vessels), bacteria can enter and cause infection. Signs that a break has reached the pulp include throbbing pain, sensitivity to hot or cold that lingers, swelling around the tooth, or visible discoloration. At this point, a crown alone isn’t enough. You’ll need a root canal first.
During a root canal, your dentist removes the infected or damaged pulp, cleans and disinfects the inner chamber, fills it, and then seals the tooth. A crown is placed over it afterward for strength. The procedure sounds intimidating, but with modern anesthesia it’s comparable in discomfort to getting a filling. Most people return to normal activities the next day.
Skipping a root canal when one is needed is where things get dangerous. Untreated pulp damage leads to a dental abscess, a pocket of pus that forms at the root. An abscess can develop over weeks to months, and once it forms, you’ll notice throbbing pain, facial swelling, and sometimes difficulty swallowing or opening your mouth. Left untreated further, the infection can spread to the jaw, neck, and in rare but serious cases, the brain or bloodstream. People with diabetes, weakened immune systems, or who are malnourished face higher risk for these complications.
When the Tooth Can’t Be Saved
If the tooth is cracked vertically down through the root, or if decay and infection have destroyed too much structure, extraction becomes necessary. After extraction, the two main replacement options are a dental bridge and a dental implant.
A dental bridge anchors an artificial tooth to the teeth on either side of the gap. It usually requires just two dental visits over a couple of weeks. Bridges typically last 5 to 7 years, though well-maintained ones can exceed 10 years. The tradeoff is that the neighboring teeth need to be filed down to support the bridge, which permanently alters healthy teeth.
A dental implant involves placing a titanium post directly into the jawbone, then attaching a crown to it after the bone heals around the post. The entire process can take up to 6 months because you need 2 to 6 months of bone healing before the final crown is placed. The payoff for that patience is significant: implants can last 15 years or more and have a 10-year success rate of about 97%. They also don’t affect neighboring teeth and help preserve jawbone density at the site.
Why Speed Matters
A broken tooth with exposed inner tissue is essentially an open wound inside your mouth, constantly bathed in bacteria. Every day without treatment increases the chance that a simple repair turns into a root canal, and that a root canal case turns into an extraction. The financial stakes escalate just as quickly: bonding costs a fraction of a crown, a crown costs a fraction of an implant. Getting seen within 24 to 48 hours of the break gives your dentist the most options and you the least invasive, least expensive outcome.
