What is a tooth fracture?

What is a tooth fracture?
Tooth fractures can range from minor (involving chipping of the outer tooth layers called enamel and dentin) to severe (involving vertical, diagonal, or horizontal fractures of the root).
Enamel and dentin are the two outer protective layers of the tooth.
The enamel is the outermost white hard surface.
The dentin is a yellow layer lying just beneath the enamel.
Enamel and dentin both serve to protect the inner living tooth tissue called the pulp.
The visible one-third of the tooth is called the crown, while the remaining two-thirds of the tooth buried in the bone is called the root. Dental X-rays are necessary in most instances to diagnose, locate, and measure the extent of tooth fracture.

What is a serious tooth fracture?

A serious fracture is one that exposes both the dentin and the pulp tissue and should be treated promptly.
The tooth may be displaced and loose, and the gums may bleed.
To prevent the loose tooth from falling out completely, the dentist can splint the loose tooth by bonding it to the adjacent teeth to help stabilize it while the underlying bone and gums heal.
Because of the high risk of pulp death, a root canal procedure may need to be performed during the first visit.
Alternatively, the dentist may elect to only apply a sedative dressing on the splinted tooth to help calm the tooth pain.
The tooth will then be reevaluated in two to four weeks for root canal procedure followed by a dental filling or crown.
The splint is also removed at that time.
