A chip is a small piece of enamel that broke off the outside of a tooth. It looks worse than it is in most cases and is often fixable with cosmetic bonding in one visit. A crack is a line running through the tooth, sometimes visible on the surface and sometimes not. Cracks tend to grow with normal chewing, and how far the crack extends determines everything about the fix. That is why speed matters.
Dr. Zack Finnegan, DMD at Magnolia Smiles in Woodstock, GA treats both regularly. This guide explains the difference, why fast treatment matters for cracks in particular, and what each treatment usually looks like.
What is a chip
A chip is a small fracture of enamel, usually on a corner or edge of a tooth. Common causes:
- Biting something hard (candy, ice, pen).
- A fall or facial impact.
- Grinding wear.
- Damage to an already-weakened area near an old filling.
Chips are visible, sometimes rough on the tongue, and can be sensitive to cold or air. Most chips do not reach the nerve and do not cause severe pain.
What is a crack
A crack is a line running through the tooth. Categories:
- Craze lines: very shallow lines in the enamel only. Cosmetic, not structural. Usually no treatment needed.
- Fractured cusp: a cusp of the tooth is broken off (some overlap with “chip” for larger cusp fractures).
- Cracked tooth: a crack running from the biting surface down toward the root, still contained within the tooth.
- Split tooth: a crack that has completely divided the tooth into segments.
- Vertical root fracture: a crack that started in the root and extends upward.
The middle categories (fractured cusp and cracked tooth) are what “cracked tooth” usually means clinically, and they are the ones where fast treatment really matters.
Why fast treatment matters for cracks
Cracks are dynamic. Every time you bite on a cracked tooth, the two sides of the crack move slightly against each other. Two things happen with that motion:
- The crack extends. Bit by bit, the crack works its way toward the root.
- The pulp (nerve) becomes inflamed. Once the crack reaches the pulp, a root canal is required.
Caught early, a cracked tooth is often saved with a crown, no root canal needed. Left alone, the same tooth commonly ends up needing a root canal, sometimes extraction, and eventually a bridge or implant.
Fast, in this case, does not mean 3 AM. It means within days to a few weeks, not months.
How to tell if you have a chip or a crack
Signs of a chip
- Visible missing piece of enamel.
- Rough surface on the tongue.
- Mild sensitivity to air or cold.
- Minor cosmetic issue.
Signs of a crack
- Sharp pain on biting or when you release your bite.
- Pain concentrated on one specific spot.
- Sensitivity to cold that lingers.
- Sometimes no visible crack line.
- Comes and goes: feels fine most of the day, flares on certain bites.
If in doubt, assume it is a crack and get it evaluated.
Treatment options
For a chip
- Cosmetic bonding. Composite is layered onto the tooth and shaped to restore the missing corner. Usually one visit, often no numbing. Learn more about dental bonding at Magnolia Smiles.
- Smoothing (enameloplasty). Very small chips can just be smoothed.
- Veneer. For larger chips on visible teeth or when combining with other cosmetic goals.
- Crown. For chips that involve too much of the tooth for bonding to hold.
For a cracked tooth
- Crown. The most common treatment. Holds the tooth together and distributes chewing force. Learn more about dental crowns at Magnolia Smiles.
- Root canal plus crown. If the crack reached the pulp.
- Extraction plus replacement. If the crack extends below the gumline or has split the tooth. Followed by an implant or bridge.
What to do at home right now
- Rinse gently with warm water.
- Save any tooth fragments in a container. Bring them in.
- Cover a sharp edge with sugar-free gum or dental wax.
- Chew on the other side.
- Take over-the-counter pain relief as needed.
- Avoid very hot or very cold on that side.
- Call the office to be seen.

Frequently asked questions
Can I ignore a small chip?
If it is not painful and not sharp on the tongue, monitoring at your next cleaning is reasonable. Any pain or sensitivity means see the dentist sooner.
Will a cracked tooth heal?
Enamel does not heal. A crack does not close on its own. The crack often continues to grow slowly under chewing pressure.
Can bonding fix a crack?
Bonding does not hold a crack closed under chewing force. Cracks generally need a crown to stabilize the tooth.
How much does treatment cost?
Cost depends on the specific treatment. You get a written estimate before scheduling.
Is a chipped or cracked tooth covered by insurance?
Restoration of a chipped or cracked tooth is typically covered. The office verifies benefits.
What if the crack goes below the gumline?
That usually means the tooth cannot be saved. The plan then focuses on extraction and replacement.
