TYPES OF TOOTH FRACTURES
Craze lines are a relatively benign form of tooth cracks generally found in adult teeth. They’re superficial, barely noticeable cracks that only go as deep as the outer enamel. Because they’re so shallow, it’s unusual for them to pose much of a problem.
Chipped teeth are the most common kind of dental injuries. Dentists repair them by putting a tooth-colored filling or crown in its place.
The cusp is the ridge on a molar tooth. When a cusp becomes weak, it can fracture, at which point it may break off or a dentist may see fit to remove it. If the fractured cusp has resulted in damage to the pulp, a root canal and a full crown could conceivably be indicated.
If the crack in a fractured tooth runs from the chewing surface to the root, this too can damage the pulp and possibly require a root canal. If the cracked tooth does not receive treatment, it may even need to be extracted. A cracked tooth can also become a split tooth. The patient often loses a split tooth or at least a portion of it. Saving the tooth requires endodontic intervention and a restoration.
A vertical root fracture is one in which the tooth fracture starts in the root and then spreads to the chewing surface. Unfortunately, it’s not uncommon for this type of fracture to go undetected until the tooth requires a relatively elaborate corrective intervention or possibly even extraction. Whatever the precise nature of the problem, the dentist will choose the most appropriate treatment from a number of possible options.
