How to Fix a Cracked Tooth

How to Fix a Cracked Tooth
A sharp pain when you bite down signals a problem. Learning how to fix a cracked tooth helps you protect the tooth before the crack reaches the nerve or root.
A crack weakens your tooth and lets bacteria reach the inner pulp. Without treatment, the damage grows and limits your options. This guide explains the signs of a cracked tooth, the treatments dentists use, and what to do before your appointment.

Signs You Have a Cracked Tooth

Cracks do not always show on the surface of the tooth. Watch for these cracked tooth symptoms:
  • Sharp pain when you bite or release pressure.
  • Sensitivity to hot, cold, or sweet foods.
  • Intermittent pain without a clear cause.
  • Swelling of the gum around one tooth.
  • A rough or sharp edge your tongue detects.
If you notice any of these signs, book a dental exam. Early diagnosis gives you more treatment options.

Types of Tooth Cracks

Dentists classify cracks by location and depth. The type of crack determines your treatment.
  • Craze lines: Tiny lines in the outer enamel. They usually cause no pain and need no treatment.
  • Fractured cusp: A break in the chewing surface, often around a large filling. It rarely affects the pulp.
  • Cracked tooth: A crack runs from the chewing surface toward the root. Early treatment improves the chance of saving the tooth.
  • Split tooth: A crack divides the tooth into separate segments. In some cases, your dentist can save part of the tooth.
  • Vertical root fracture: A crack starts in the root and extends toward the chewing surface. Most need extraction.

How to Fix a Cracked Tooth: Professional Treatment Options

Your dentist selects a treatment based on the size, depth, and location of the crack. X-rays and 3D imaging help your dentist see how far the crack extends.

Dental Bonding

For minor cracks and chips, your dentist applies a composite resin in your natural tooth shade. The dentist shapes the resin, hardens it with a curing light, and polishes the surface. Bonding takes one visit and requires little to no enamel removal.

Dental Crown

A dental crown covers the entire visible part of the tooth. It holds the cracked sections together and stops the crack from spreading. Dentists recommend a crown for cracks deeper than the enamel and for teeth with large fillings. Digital scanners and office milling machines allow some dentists to place a crown in one visit.

Root Canal Treatment

When a crack reaches the pulp, bacteria infect the nerve and blood vessels inside the tooth. A root canal removes the infected pulp, cleans the canals, and seals the tooth. Your dentist then places a crown to protect the treated tooth. Local anesthesia keeps you comfortable during the procedure. 

Extraction and Tooth Replacement

If the crack extends below the gum line or splits the root, your dentist removes the tooth. A replacement restores chewing function and stops nearby teeth from shifting. 

What to Do Before Your Dental Appointment

No home remedy repairs a cracked tooth. These steps reduce pain and protect the tooth until your visit:
  • Rinse your mouth with warm salt water to clean the area.
  • Take a nonprescription pain reliever as directed on the label.
  • Hold a cold compress against your cheek for 15 minutes to reduce swelling.
  • Chew on the opposite side of your mouth.
  • Avoid hard, sticky, hot, and cold foods.
  • Cover a sharp edge with dental wax or sugarless gum.
Call your dentist the same day if you notice facial swelling, fever, or severe pain at night. 

Why You Should Not Delay Treatment

A crack does not heal on its own. Enamel contains no living cells, so it has no way to repair itself. Each bite pushes the crack deeper into the tooth. Delay leads to:
  • Infection of the Pulp: Bacteria enter the crack and reach the pulp. The infection inflames the nerve, causing throbbing pain, sensitivity, and tenderness.
  • Dental Abscess: An untreated pulp infection spreads to the root tip. Pus then collects in the gum or jawbone, causing swelling.
  • A Split Tooth: Chewing forces push the crack deeper with each bite. The tooth eventually divides into pieces, which limits your treatment options.
  • Tooth Loss: A crack below the gum line or through the root leaves nothing to restore. Your dentist then removes the tooth.
Waiting also narrows your choices when you and your dentist decide how to fix a cracked tooth. Early treatment preserves more of your natural tooth structure.

How to Prevent Cracked Teeth

These habits lower your risk of a cracked tooth:
  • Wear a Night Guard: Wear a custom night guard if you grind or clench your teeth.
  • Protect Your Teeth During Sports: Wear a mouthguard during contact sports. 
  • Avoid Hard Foods and Objects: Avoid chewing ice, hard candy, pens, and popcorn kernels.
  • Stop Using Your Teeth as Tools: Do not use your teeth to open packages or bottles.
  • Schedule Regular Dental Checkups: Visit your dentist every six months for exams and cleanings.

Get the Right Treatment for Your Cracked Tooth

Fixing a cracked tooth starts with a professional diagnosis. The right treatment depends on the depth and location of the crack. Bonding repairs minor cracks, crowns protect weakened teeth, and root canal treatment removes infection from the pulp. Extraction and replacement restore function when the tooth has no chance of recovery. Act at the first sign of biting pain or sensitivity.

FAQs

No. Enamel has no living cells and does not regenerate. The crack remains and often grows without dental treatment.
Bonding takes one visit of 30 to 60 minutes. A crown takes one or two visits. Root canal treatment takes one or two visits, each lasting 60 to 90 minutes.
The cost depends on the treatment. Bonding costs less than a crown, and a root canal with a crown costs more. Most dental insurance plans cover part of restorative treatment.
Small cracks often do not appear on standard X-rays. Dentists use magnification, a bite test, special dye, and 3D imaging to locate them.

Eat soft foods and chew on the opposite side until your appointment. Avoid hard, sticky, and extremely hot or cold foods.
