Cracked Teeth

Cracked Teeth

A tooth may crack for a variety of reasons, and in some cases, cracks may not be visible to the naked eye. If you experience pain when chewing and/or sensitivity to temperature changes and/or pressure, you may suffer from cracked teeth or cracked tooth syndrome (CTS).

The interior of a tooth, called the pulp, resides within a chamber beneath a protective layer of enamel and a sensitive layer of dentin. Pulp consists of blood vessels, connective tissues, and nerves. The nerves carry pain signals to the brain. With a cracked tooth, pressure and release of pressure irritate the nerves within the pulp which can cause pain that ranges from irritating to acute. Over time, this can cause the pulp to become permanently damaged, resulting in consistent pain.

What causes cracked teeth? 

Human teeth are strong.  

However, teeth can become susceptible to wear, crazing (surface-level, web-like cracking), chipping, and cracking over time. Causes of cracked teeth include, but are not limited to: 

  • Eating hard foods
  • Biting on a hard object
  • Trauma to the mouth 
  • Bruxism (habitual teeth grinding) 
  • Large fillings

Can cracked teeth be restored?

The endodontist, Dr. Chung, may recommend dental bonding made of tooth-colored composite resin, to close a crack. Bonding is an in-office restoration that a general dentist or endodontist can complete in one visit.  

A more significant crack may need a dental crown for restoration which can be completed by your general dentist 

Once a crack has become large enough to allow bacteria to enter the nerve space, an infection can result. Root canal therapy can save an internally infected tooth. 

If a crack extends to the gumline, restoration is usually not feasible. The tooth will likely need extraction and replacement with a bridge or dental implant.
