What a dentist does for a broken tooth depends on how much of the tooth is damaged and whether the break reaches the nerve inside. Small chips often need nothing more than smoothing or a simple bonding repair. Deeper breaks that expose the inner layers may require a crown, root canal, or in some cases, extraction. Here’s what to expect at each stage.
What to Do Before You Get to the Dentist
If you’ve just broken a tooth, rinse your mouth gently with warm water to clean the area. If there’s bleeding, press a piece of gauze or a damp paper towel against the spot and bite down lightly. Over-the-counter pain relievers and a cold compress on the outside of your cheek can help manage pain and swelling until your appointment.
If you have the broken piece, save it. Place it in a small container with milk or your own saliva. Don’t wrap it in tissue or cloth, and don’t scrub it clean. Tap water can damage the cells on the fragment’s surface. Your dentist may be able to reattach it in some cases, particularly with front teeth.
How the Dentist Evaluates the Break
Not all fractures are visible to the naked eye. Your dentist will start with a visual exam and X-rays, but they have a few other tools for tricky cases. Transillumination involves passing a bright light through the tooth to reveal hairline cracks that don’t show up on film. A bite test, where you chomp down on a small stick or rubber instrument, helps pinpoint exactly which part of the tooth hurts under pressure. A periodontal probe, a thin metal instrument slid along the gumline, can detect cracks that extend below the surface by measuring bone loss around the tooth.
The depth of the fracture determines everything. Dentists generally think about breaks in three tiers: those that only affect the outer enamel, those that reach the yellowish layer underneath (called dentin), and those that go all the way into the pulp, the soft tissue containing the nerve and blood supply.
Minor Chips: Bonding or Smoothing
A chip that only involves the enamel is the least serious type. You might feel a rough or sharp edge with your tongue, but there’s usually no pain. For very small chips, the dentist may simply smooth and polish the edge so it doesn’t irritate your cheek or lip. That can be done in minutes with no numbing needed.
For slightly larger chips, especially on front teeth, composite bonding is the go-to fix. The dentist applies a tooth-colored resin directly onto the damaged area, sculpts it to match the original shape, and hardens it with a curing light. The whole process typically takes 30 to 60 minutes per tooth and doesn’t require anesthesia unless the break is close to a sensitive area. Bonding material generally lasts three to ten years before it needs to be touched up or replaced. It’s one of the least expensive cosmetic repairs, usually a fraction of the cost of a crown.
Moderate Breaks: Crowns and Onlays
When a break goes deeper into the dentin layer, you’ll likely feel sensitivity to air, cold drinks, or touch. The exposed dentin communicates more directly with the nerve, so leaving it unprotected isn’t an option. If enough tooth structure remains, the dentist may place a crown: a cap that covers the entire visible portion of the tooth above the gumline.
Getting a crown usually takes two visits. At the first, the dentist shapes the remaining tooth into a smaller peg, takes impressions or digital scans, and fits you with a temporary crown. The permanent crown, made from ceramic, zirconia, or porcelain fused to metal, arrives from a lab in one to three weeks. Some offices have same-day milling technology that can produce a crown in a single appointment. Without insurance, a single crown typically costs $800 to $2,500, with most ceramic or zirconia crowns averaging around $1,300.
For back teeth where the break removes one or two cusps (the raised points on the chewing surface) but leaves most of the tooth intact, an onlay may be a better fit. It’s a partial crown that covers only the damaged portion rather than wrapping the entire tooth.
Deep Fractures: When a Root Canal Is Needed
If the break exposes the pulp, you’ll know it. There may be visible pink or red tissue at the center of the fracture, possibly bleeding, and sharp pain with temperature changes or even breathing through your mouth. This is the most urgent type of fracture to treat because exposed pulp is vulnerable to infection.
When the pulp is still healthy, the dentist may be able to cap the exposed area and save the nerve. But if the nerve is already inflamed beyond recovery, producing spontaneous or lingering pain, a root canal is the standard treatment. During a root canal, the dentist removes the damaged pulp tissue, cleans and disinfects the inside of the tooth, fills the empty canals, and then places a crown on top. The procedure itself is done under local anesthesia and feels similar to getting a deep filling. Most people are back to normal within a few days.
A root canal adds significant cost. Without insurance, the procedure runs roughly $700 to $2,100 depending on which tooth is involved (molars cost more because they have more canals). Add the crown on top of that, and you’re looking at a combined cost of $1,500 to $4,000 or more. If enough tooth structure has been lost, the dentist may also need to place an internal post and buildup ($250 to $650) to give the crown something to hold onto.
When the Tooth Can’t Be Saved
Some fractures run vertically down the root, splitting the tooth in a direction that can’t be repaired. These vertical root fractures are particularly difficult because they often aren’t obvious right away. You might notice a dull ache, sensitivity when biting, or a localized pocket of gum swelling that comes and goes. In most cases, extraction is the only option for a complete vertical root fracture, especially when the surrounding bone and gum tissue have already started to break down.
A tooth is also typically unsaveable when the fracture extends well below the gumline into the bone, when the root is shattered into multiple fragments, or when infection has already spread to the bone at the root tip and the remaining tooth structure is too compromised to restore.
After extraction, you have several replacement options. A dental implant, a titanium post surgically placed in the jawbone and topped with a crown, is the most durable long-term solution but also the most expensive and time-intensive, often requiring several months from start to finish. A fixed bridge uses the neighboring teeth as anchors to support a false tooth in the gap. A removable partial denture is the most affordable option and can be made relatively quickly.
Front Teeth vs. Back Teeth
Where the break happens influences which repair your dentist recommends. Front teeth are under less chewing force, so bonding and veneers work well for cosmetic repairs. A veneer is a thin porcelain shell bonded to the front surface of the tooth, and it’s a good option when a front tooth has a moderate chip or crack that bonding alone can’t disguise convincingly. Veneers look more natural than composite bonding over time because porcelain resists staining better.
Back teeth take the brunt of your chewing force, sometimes hundreds of pounds of pressure per bite on molars. That’s why crowns and onlays are more common for broken back teeth. Bonding on a molar wears down and chips much faster than it would on a front tooth, so it’s generally reserved for very minor repairs in the back of the mouth.
What Recovery Looks Like
For bonding, there’s essentially no recovery. You can eat normally as soon as you leave the office, though your dentist may suggest avoiding very hard or sticky foods on the repaired tooth for the first 24 hours.
After a crown, the area may be sore for a day or two, mostly from the numbing injection and the work done to shape the tooth. Sensitivity to hot and cold is common for the first few weeks as the tooth adjusts. If you have a temporary crown while waiting for the permanent one, avoid sticky foods that could pull it off, and chew on the opposite side when possible.
Root canal recovery varies but most discomfort resolves within three to five days. Some tenderness when biting is normal during this window. If pain intensifies rather than improving after the first few days, or if swelling develops, that warrants a call back to the dentist.
