Cracked Tooth: Types, Symptoms, and Treatment Cost

Editorially reviewed by the Dental.me Editorial Team · Updated July 2026

A cracked tooth is a break or fracture line in the hard outer surface of a tooth, and the right treatment depends entirely on how deep the crack runs. A shallow surface line in the enamel may need nothing at all, while a crack that reaches the pulp or splits the root can require a crown, a root canal, or removal. Because a cracked tooth can look minor yet hurt badly, the safest move is to have a dentist examine it, especially if you have pain when you bite or release, swelling, or sensitivity that will not settle.

This guide walks through the five recognized crack types, the symptoms that tell them apart, how each is treated, and what those treatments typically cost in the United States.

What are the five types of cracked teeth?

Dentists group tooth cracks into five categories. The category matters far more than how the crack looks, because a small visible line and a deep invisible one can behave very differently.

Craze lines

Craze lines are tiny, shallow cracks limited to the enamel, the hard outer layer. They are extremely common in adults, cause no pain, and are almost always a cosmetic concern only. Most people have several and never notice them.

Fractured cusp

A fractured cusp happens when a piece of the chewing surface breaks off, often around a large filling. Because the break usually does not reach the pulp, it is frequently one of the more manageable cracks and rarely causes severe pain.

Cracked tooth

A true cracked tooth has a crack that runs from the chewing surface toward the root. The tooth is still in one piece, but the crack can extend into the pulp over time. Caught early, the tooth can often be saved with a crown; left too long, it may need root canal treatment or extraction.

Split tooth

A split tooth is usually the end stage of an untreated cracked tooth. The crack has grown until the tooth separates into distinct segments. A split tooth can rarely be saved whole, though in some cases part of it can be retained.

Vertical root fracture

A vertical root fracture begins at the root and travels upward. These cracks often show few symptoms until the surrounding bone and gum become infected. They usually end in extraction because the fracture runs through the root itself.

What are the symptoms of a cracked tooth?

The signature symptom of a cracked tooth is pain that comes and goes, rather than a constant ache. Many people can chew normally for weeks and only feel a sharp jolt at certain moments.

• Pain on biting or release. A sharp pain when you bite down, or oddly when you let go, is the classic sign. Releasing pressure lets the crack flex, which irritates the inner tissue.
• Sensitivity to hot, cold, or sweet. A crack can expose the sensitive inner layers, so temperature or sugary foods trigger a quick zing.
• Pain that is hard to pinpoint. Cracked teeth often produce vague pain that is difficult to locate, which is why they can be tricky to diagnose.
• Intermittent, not constant. Unlike a cavity that aches steadily, cracked-tooth pain tends to flare only with specific triggers.

Some symptoms signal that the problem has moved beyond the tooth and needs prompt attention.

How is a cracked tooth treated?

Treatment follows the depth of the crack. The goal is always to keep as much natural tooth as possible, but a crack that reaches the pulp or root changes what is realistic. Here is how dentists generally step through the options, from least to most involved.

1. Monitoring or polishing (craze lines). Shallow enamel cracks usually need no treatment. A dentist may smooth or polish them for appearance.
2. Bonding. For small chips or shallow cracks, tooth-colored composite resin can be bonded over the area to restore the surface and protect it.
3. Crown. A cap that covers the whole tooth is the workhorse for a fractured cusp or a cracked tooth. It holds the tooth together and spreads out the force of chewing so the crack cannot spread.
4. Root canal, then a crown. When a crack reaches the pulp, the inflamed or infected inner tissue is removed with root canal treatment, then the tooth is crowned. This saves teeth that would otherwise be lost.
5. Extraction. A split tooth or a vertical root fracture often cannot be saved. The tooth is removed, and the gap can later be restored with an implant or bridge.

Only a dentist can tell how deep a crack goes, often with a bite test, a special dye, magnification, or an X-ray. That is why two teeth that look identical can need very different care. A directory like Dental.me’s dentist-near-me search can help you find a practice that handles crack diagnosis and same-week care.

How much does cracked tooth treatment cost?

Cost tracks closely with severity. Bonding is the least expensive option, while an extraction followed by an implant is the most. The ranges below are typical US out-of-pocket figures before insurance, which varies widely by region and by dentist.

Two things move the price most: which tooth is involved (molars cost more than front teeth) and where you live. Dental costs in a big metro like Chicago can run noticeably higher than a rural area, and specialist care through an endodontist or oral surgeon may carry its own fee. To compare typical prices across regions before you book, our dental market data shows how treatment costs vary by city and state.

Can you prevent a cracked tooth?

You cannot prevent every crack, but you can lower your risk. Avoid chewing ice, hard candy, popcorn kernels, and pens. If you clench or grind your teeth, a custom night guard protects them from the repeated force that causes fractures. Keep up with regular checkups so small cracks and worn fillings are caught before they spread, and wear a mouthguard for contact sports.

Key takeaways

• A cracked tooth ranges from harmless craze lines to a tooth-ending vertical root fracture; the depth of the crack decides everything.
• The hallmark symptom is sharp pain on biting or release, along with temperature sensitivity, that comes and goes rather than aching constantly.
• Treatment scales with severity: monitoring, bonding, a crown, a root canal plus crown, or extraction with an implant.
• Typical US costs run from about $150 for bonding to $6,000 for extraction and an implant.
• Pain with swelling, fever, or a loose tooth needs prompt dental care because it can signal infection.
