Cracked teeth are typically caused by one of three things: an injury, undue pressure from grinding or clenching over a long period of time, or the breakdown of prior fillings that may break down and leak. In some cases, a cracked tooth may eventually split into two pieces, making it impossible to save the tooth. In many cases, a cracked tooth can be saved by your endodontist with a filling or a crown. Left untreated, cracked teeth can also lead to damage to the soft inner tissue, or pulp, of your tooth. When the inner pulp becomes damaged or diseased, a root canal is typically the only way to save the tooth from extraction.
