If your tooth is broken, chipped, or fractured, see your dentist as soon as possible. Otherwise, your tooth could be damaged further or become infected, possibly causing you
to end up losing the tooth.
Dental Cap or Crown
If a large piece of tooth breaks off or the tooth has a lot of decay, the dentist may grind or file away part of the remaining tooth and cover it with a crown, or tooth-shaped cap, made to protect the tooth and improve its appearance. Permanent crowns can be made from metal, porcelain fused to metal, all resin, or all ceramic. Different types have different benefits. All-metal crowns are the strongest. Porcelain and resin crowns can be made to look nearly identical to the original tooth.
If the entire top of the tooth is broken off but the root is still intact, the dentist or an endodontist (a dentist who specializes in root canals) may perform a root canal and place a pin or a post in the canal, and then build up enough of a structure onto which a crown can be made. Later, the dentist can cement the crown over the pin or post-retained restoration.
If a front tooth is broken or chipped, a dental veneer can make it look whole and healthy again. A dental veneer is a thin shell of tooth-colored porcelain or resin composite material that covers the whole front of the tooth (much like a false nail covers a fingernail) with a thicker section to replace the broken part of the tooth.
If a tooth chip or break is large enough to expose the pulp -- the center of the tooth containing nerves and blood vessels -- bacteria from the mouth can enter and infect the pulp. If your tooth hurts, changes color, or is sensitive to heat, the pulp is probably damaged or diseased. Pulp tissue can die and if it's not removed, the tooth can become infected and need to be extracted. Root canal therapy involves removing the dead pulp, cleaning the root canal, and then sealing it.
