Cracked Tooth Syndrome Treatment in St Leonards

By: damian@nestdental.com.auUpdated: February 25, 2026

Experiencing sharp pain when biting or sensitivity that comes and goes? You may have Cracked Tooth Syndrome - a condition where small, often invisible cracks in a tooth cause discomfort and sensitivity. Early diagnosis is essential to prevent the crack from worsening and protect your tooth from further damage.

What Is Cracked Tooth Syndrome?

Cracked Tooth Syndrome (CTS) occurs when a tooth develops incomplete fractures that may not be visible on X-rays. These cracks can irritate the inner pulp of the tooth, leading to intermittent pain - particularly when chewing or releasing pressure. Left untreated, a cracked tooth can deepen, potentially leading to infection or the need for extraction.

  • Pain when biting or chewing that comes and goes
  • Sensitivity to hot, cold, or sweet foods
  • Discomfort that's hard to localise
  • Pain when releasing biting pressure

What Causes a Cracked Tooth?

Cracks can develop for a number of reasons:

  • Grinding or clenching (bruxism)
  • Large existing fillings that weaken the tooth
  • Biting on hard objects or foods
  • Sudden temperature changes in the mouth
  • Age-related wear and weakening of tooth structure
  • Trauma or injury to the mouth

How We Diagnose Cracked Teeth

Cracked teeth can be challenging to diagnose because the fractures are often too small to see on standard X-rays. We use a combination of techniques including visual examination with magnification, bite tests to reproduce the pain, transillumination (shining light through the tooth), and digital imaging to identify the location and extent of the crack.

Treatment Options

Treatment depends on the size, location, and severity of the crack.

1

Dental Crown

A crown covers and protects the cracked tooth, preventing the crack from spreading and restoring function.

2

Root Canal Treatment

If the crack extends into the pulp, root canal therapy may be needed to remove the damaged tissue before placing a crown.

3

Dental Bonding

For minor cracks, bonding material can seal the crack and protect the tooth.

4

Extraction (Last Resort)

If the crack extends below the gum line or splits the tooth, extraction with a replacement option may be necessary.
