When the cusp of the tooth cracks and starts flexing while biting, it may cause sharp pain. This is called cracked tooth pain. Sometimes the sharp pain will only occur occasionally when the cusp is bitten at just the right angle. Often cold, hot or sweets will also cause the sharp pain by seeping into the crack. The causes of broken tooth don’t matter as much as the treatment. Cracked tooth syndrome is corrected by putting a crown over and around the tooth to hold the tooth together. If left untreated, the cusp will eventually fracture, causing the possible need for root canal therapy or even extraction.
A cracked tooth cannot heal by itself. At the start the cracking could be very small as well as unobtrusive. But in case it goes untreated, then the crack can progress further in the tooth or even much deeper. Hence, the earlier the cracks get treated, then the more possibly the tooth can be saved.
TYPES OF CRACKS
A craze is a surface crack that shows as a line on the tooth enamel. Although it may not look very attractive, a craze usually does not need treatment. If there are cosmetic reasons the tooth with the crazed enamel can be treated with a veneer or bonding.
Fracture is a crack, usually through the cusp of a tooth,that causes part of the tooth to grow weaker and even break off. A fractured cusp usually can be restored with a crown. However if the fracture extends into the nerve or the jawbone, then a root canal or extraction will be necessary.
Split is a vertical crack that extends so deeply into the tooth that it can separate into pieces. Depending on the location and severity of the split, the tooth may be saved or need removal.
Root fracture is a crack that begins in the root of the tooth and slowly extends upward. This type of crack may not be noticed until the surrounding gum and bone show signs of infection. In this situation, the tooth usually needs removal.
