Almost every fracture is repairable, and the right fix comes down to one thing: how deep the damage runs. Surface lines in the enamel often need nothing more than smoothing. A break through the chewing surface usually calls for bonding, an onlay, or a crown.
Once the split reaches the pulp, endodontic therapy enters the picture. A fracture running below the gum line normally means removal and replacement. Out of pocket, that range spans roughly $175 for simple reshaping up to around $6,900 for a full extraction and implant replacement.
This guide covers what dentists do to fix cracked tooth damage, what each option costs, how long it takes, and how to work out which one you are likely to need.
Infected Root Canal
What is a Cracked Tooth?
A crack is any break or split in the enamel or the deeper layers underneath. It can be a faint line affecting only the outer surface, or it can run far enough to reach the root.
Warning signs include sharp pain when you bite down, sensitivity to hot or cold, swelling around the gum line, or a tooth that has split in half with no pain at all. Any one of these is reason enough to get checked.
Common causes include biting hard foods such as nuts, candy, or ice; trauma from accidents or sports; grinding (bruxism); large existing fillings that leave less natural structure behind; and ordinary wear with age. Fracture risk also tends to rise over time, since enamel wears thinner and older fillings leave less natural structure holding the tooth together.
Not every crack needs treatment. A faint craze line that does not hurt or catch on your tongue is often just watched at your regular checkups rather than repaired right away.

Cracked Tooth Repair Options and What Each One Costs
Once your dentist confirms a fracture, the recommendation depends on severity, position in the mouth, and whether the pulp is involved. Below are the paths available for treating cracked tooth damage, arranged from least to most involved. If you have wondered how are cracked teeth fixed in practice, this is the full range
1. Reshaping and Polishing
Shallow craze lines and rough edges often need nothing beyond contouring. Your dentist smooths the surface, removes sharp catch points, and polishes the enamel. It is the quickest fix available and takes about half an hour per tooth.
2. Bonding or Filling
Small chips and shallow breaks respond well to tooth-colored resin. The material is applied, shaped, and cured under light, restoring strength and appearance in one visit. This works well for filling cracked tooth surfaces where decay sits alongside the damage.
3. Onlays and Dental Crowns
When a cusp breaks away, or a large section of structure is compromised, partial coverage with an onlay or full coverage with a dental crown protects what remains. Expect two visits: preparation and scanning first, then fitting of the permanent restoration about three weeks later.
If you’re weighing the price difference between the two, this crown cost breakdown walks through what drives the total.
4. Cracked Tooth Root Canal Treatment
When the fracture reaches the pulp, the soft tissue inside, a root canal becomes necessary. The procedure removes damaged pulp, cleans and shapes the canal, seals it, then finishes with a crown for protection. Pricing follows position in the arch, and molars cost more than front teeth because they have more canals.
For a fuller walkthrough of what happens chairside, see how long a root canal procedure typically takes.
5. Extraction and Replacement
A vertical root fracture or a fully split tooth usually cannot be saved, and tooth removal becomes the only realistic path. A bone graft placed at the same time preserves the socket for an implant later.
| Repair Option | When It's Used | Out-of-Pocket Cost | Chair Time | Warranty |
|---|---|---|---|---|
| Reshaping & polishing | Craze lines, rough or sharp edges | $175 to $450 per tooth | 30 mins per tooth | — |
| Composite bonding | Small chips, shallow surface breaks | $950 | 1 hour | — |
| Filling (1 to 4 surfaces) | Damage combined with decay | $300 to $450 | 40 mins to 1 hour | 1 year |
| Onlay | Fractured cusp, pulp still healthy | $1,950 | 1 hour | — |
| Crown | Major structural loss, or after a root canal | $1,950 | 1 hr prep, 1 hr fitting 3 weeks later | 5 years |
| Resin veneer | Visible front tooth damage | $950 | 1 hour | — |
| Porcelain veneer | Visible front tooth damage, longer lasting | $2,323 | 1 hour | — |
| Root canal | Break reaching the pulp | $1,400 front, $1,600 premolar, $1,800 molar | 1.5 hrs, or 1 hr with an endodontist | — |
| Extraction with bone graft | Split tooth or vertical root fracture | $950 | — | — |
| Implant body | Replacing a tooth that cannot be saved | $2,650 | 1 hour | — |
| Abutment & crown | Completing the implant restoration | $3,300 | — | — |

Cracked Molar Repair: Why Back Teeth Behave Differently
Molars absorb the heaviest chewing forces in your mouth, so cracked molar repair follows different logic than work on front teeth. Damage here usually starts as a fractured cusp around an old filling rather than a clean vertical line.
Because molars carry so much load, partial repairs frequently fail. A bonded patch on a back tooth that flexes under pressure will often loosen within months, which is why coverage is the more durable answer.
Cracked molar treatment options fall into three tiers. A fractured cusp with healthy pulp takes an onlay or crown. If the split has reached the nerve, endodontic therapy plus a crown applies. If the fracture runs vertically into the root, the tooth is not restorable.
Molars also sit where you cannot see them, so damage back there often announces itself only through pain on release, that sharp twinge when you stop biting rather than when you press down.
Cracked Front Tooth Repair
Front teeth are what people see when you speak, so cracked front tooth repair balances structure against appearance. Damage here is more visible and less load-bearing than on molars, which opens options that would not hold up at the back.
Dental Veneers
Porcelain or composite shells cover the visible surface and correct both the crack and any discoloration around it. Each is fitted in about an hour of chair time, with laboratory work in between.
Dental Bonding
For minor chips and superficial lines, dental bonding is the faster, lower-cost route. Resin is applied directly, shaped by hand, and cured in a single visit with no laboratory wait.
Crowns for Front Teeth
Where the break is deeper and structure has been lost, full coverage restores strength while keeping a natural look. It is the more durable choice when a veneer would sit on too little remaining enamel. If you’re still deciding between the two, this guide to veneers versus crowns compares them side by side.
What Happens With a Cracked Tooth If You Ignore It
Damage that feels manageable early rarely stays that way. What happens with a cracked tooth left alone is a predictable sequence, and each stage costs more to reverse than the one before it. The same pattern holds across dental issues generally, as covered in this look at the risks of delaying emergency dental treatment.
Infection and Abscess Formation
A fracture gives bacteria a route into the pulp chamber. Once inside, infection can develop into an abscess that spreads to surrounding gum tissue and, in advanced cases, into the jaw. If a root canal has already been done and the tooth still hurts, it’s worth reading about whether an infected root canal needs to be extracted.
Tooth Loss
Cracks widen under normal chewing pressure. A fracture that could have been crowned can progress to the point where extraction is the only remaining option.
Jawbone Deterioration
Bone needs stimulation from a root to hold its volume. After a tooth is lost, the ridge underneath begins to resorb, which is why a graft at the time of extraction matters.
Increased Pain and Sensitivity
Mild discomfort turns sharp and persistent as the split deepens and exposes dentin and nerve tissue to temperature and pressure.
What to Expect During and After Cracked Tooth Repair
When to Book a Dental Checkup for Cracked Teeth
Book a dental checkup for cracked teeth as soon as you notice pain on biting, new sensitivity, a rough edge your tongue keeps finding, or a visible line in the enamel. Waiting rarely improves the outcome.
Book same day if there is swelling, throbbing that keeps you awake, or a piece has come away. Smile Lab is open 9 am to 7 pm on weekdays and 9 am to 5 pm at weekends, and same-day or next-day appointments are available in many cases. For the fuller list of what counts as urgent, see these dental emergency signs.
| Visit Type | What's Included | With PPO Insurance | Without Insurance |
|---|---|---|---|
| Emergency visit | Assessment of pain, swelling, or a broken piece | Covered by your plan | $99 flat |
| New patient exam | Hygiene cleaning, digital X-rays, doctor exam, written plan | Covered by your plan | $250 |

How Does a Dentist Fix a Cracked Tooth, Step by Step
The sequence stays consistent regardless of which repair you need. Understanding how a dentist fixes a cracked tooth removes most of the uncertainty before you sit down.
Diagnosis comes first, then anesthesia if the work requires it, then removal of damaged or decayed structure. Your dentist either restores directly with resin in the same visit, or scans for a laboratory-made crown, onlay, or veneer and fits a temporary meanwhile. Permanent restorations are cemented at a follow-up.
Diagnosing a Fracture
Fractures are difficult to spot, and several do not appear on standard imaging at all. Your dentist works through a sequence of checks:
- Visual examination under magnification for visible lines and edges
- A bite stick test, where you bite down and report pain on release
- Transillumination, passing light through the enamel so a crack casts a shadow
- Staining dye applied to the surface to reveal hairline damage
- Dental X-rays to assess surrounding bone and rule out related problems
- Cone beam CT imaging, a 3D scan showing bone loss that suggests a deeper split
- Periodontal probing to measure any isolated pocket forming alongside the crack
Inflammation limited to one tooth is often the giveaway for a vertical root fracture, since the split creates a narrow channel that traps bacteria.
The Repair Appointment
Fixing a cracked tooth is usually done across one or two visits. Local anesthesia keeps things comfortable, though lighter work such as bonding or polishing frequently needs none.
Direct repairs finish in a single appointment. Anything made in a laboratory, meaning crowns, onlays, and porcelain veneers, involves a preparation visit followed by fitting roughly three weeks later.
Recovery Afterwards
Mild sensitivity to hot and cold for a few days is normal and settles on its own. Avoid chewing hard foods on that side, keep up with brushing and flossing, and attend any follow-up.
Most people return to their routine the same day, particularly after bonding, polishing, or veneer placement. Root canals and extractions can cause tenderness for several days.
What to Do Before Your Appointment
You cannot repair a fracture at home, and no rinse or paste will close one. Enamel contains no living cells capable of regenerating, so the damage does not reverse itself. What you can do is stay comfortable and avoid making things worse, and this guide to emergency tooth pain relief covers the same ground in more depth.
Rinse with warm salt water to keep the area clean. Hold a cold compress against the outside of your cheek to limit swelling. Over-the-counter anti-inflammatory medication helps with pain if you can take it safely.
Chew on the opposite side and skip anything hard, sticky, or very hot and cold. If a sharp edge catches your tongue, dental wax from a pharmacy covers it temporarily. Do not apply aspirin directly to the gum, which burns the tissue rather than helping.

Common Types of Cracks Dentists Deal With
- Craze Lines: Superficial lines in the enamel only. Usually cosmetic and need no repair.
- Fractured Cusp: Part of the chewing surface breaks away, often around an existing filling. Typically restored with an onlay or crown.
- Cracked Tooth: A vertical break running from the biting surface toward the gum line. Frequently needs endodontic therapy followed by coverage.
- Split Tooth: The break has separated the tooth into distinct segments. Extraction is the usual outcome.
- Vertical Root Fracture: Starts below the gum line and travels upward. Often symptomless until infection develops, and almost always requires removal.
| Crack Type | What's Happening | Usual Repair | How Urgent |
|---|---|---|---|
| Craze lines | Fine lines in the enamel surface only | Polishing, or nothing at all | Routine |
| Fractured cusp | A chewing surface piece breaks away, often near an old filling | Onlay or crown | Within weeks |
| Cracked tooth | Vertical break from the biting surface toward the gum | Root canal, then a crown | Prompt |
| Split tooth | Break has separated the tooth into segments | Extraction, then implant or bridge | Urgent |
| Vertical root fracture | Starts below the gum line and travels upward | Extraction with bone graft | Urgent once symptoms appear |
Frequently Asked Questions
Can a cracked tooth heal on its own?
No. Enamel cannot regenerate, so a fracture will not close by itself. Prompt repair stops it widening and reduces the chance of infection reaching the pulp.
How long does cracked tooth repair take?
Bonding, fillings, and reshaping finish in one appointment of 30 minutes to an hour. Crowns, onlays, and porcelain veneers take two visits about three weeks apart. Implant replacement after extraction runs across several months.
Does a fracture always hurt?
No, and that is what makes them risky. Craze lines and many vertical root fractures produce no symptoms until infection sets in, which is why examinations catch problems patients have not noticed.
Is a cracked tooth an emergency?
Treat it as urgent if there is swelling, severe pain, bleeding, or a piece has broken away. A painless hairline crack is less pressing but still needs examining, because you cannot judge depth by looking.
What happens if I wait?
A fracture that starts small rarely stays that way once it is under daily biting force. Damage that bonding could fix today may need a crown in a few months and extraction later, so cost and invasiveness both climb the longer it sits.

Conclusion
Fractures are not always painful, and they should never be ignored. Even a molar split in half with no discomfort can progress to infection or loss. Prompt cracked tooth repair relieves symptoms and preserves the natural structure you still have. If you suspect damage or notice any symptom above, book an examination. From polishing and bonding through to crowns, endodontic therapy, and implant restoration, the right cracked tooth treatment depends on depth, and depth is something only an examination can establish.
