Cracked Teeth

Back to Patient Education

Introduction

Cracked teeth can result from grinding or clenching your teeth and chewing on hard objects, such as ice or hard candy.  Cracked teeth may cause on again, off again pain and temperature sensitivity.  You should contact your dentist as soon as you experience the symptoms of a cracked tooth.  Early diagnosis and treatment is associated with the best treatment options.  An untreated cracked tooth only gets worse and eventually leads to tooth loss.
 
You tooth has two hard outer protective layers, the enamel and dentin.  Beneath the dentin is pulp.  Tooth pulp is soft.  It contains blood vessels and nerves.  A cracked tooth has a crack that extends from the tooth’s chewing surface to the root.  The tooth does not separate in to two different pieces.  However, because of the position of the crack, the pulp may be damaged.

Symptoms

Your tooth may hurt, especially while chewing.  You may feel a momentary sharp pain when you chew.  Your tooth may be sensitive to hot or cold temperatures.  Eventually, a cracked tooth may hurt all of the time.

Diagnosis

You should contact your dentist as soon as you suspect that you have a cracked tooth to ensure the best treatment results.  Your dentist will examine your teeth to diagnose a cracked tooth.  A harmless dye may be placed on your tooth to highlight the crack.  Your dentist may shine a light on your tooth.  In a healthy tooth, the light will pass through the tooth.  In a cracked tooth, the light will stop at the crack and not pass through the entire tooth.

Treatment

A crown will be placed on your tooth to restore stability and protect the tooth.  If the pulp of your cracked tooth is affected, your tooth may need a root canal treatment.  Cracked teeth need to be treated to prevent tooth loss.  If the crack extends below your gum line, you may need to have your tooth removed.
