Repairing a Chipped or Broken Tooth
Dental Cap or Crown continued...
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.
Getting a crown usually takes two visits to the dentist’s office. During the first visit, your dentist may take X-rays to check the roots of the tooth and surrounding bone. If no further problems are detected, the dentist will numb the tooth and surrounding gum and then remove enough of the remaining tooth to make room for a crown. If a break or chip has left a large piece of the tooth missing, your dentist can use a filling material to build up the tooth to hold the crown. Next, your dentist will use a putty-like material to make an impression of the tooth receiving the crown as well as the opposing tooth (the one it will touch when you bite down). The impressions are sent to a lab where the crown is made. In the meantime, your dentist may place a temporary crown made of acrylic or thin metal.
During the second visit, typically two to three weeks later, your dentist will remove the temporary crown and check the fit of the permanent one before permanently cementing it in place.
Some dental offices, however, have special digital milling technology that enables them to make a crown the same day without taking a putty impression.
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.
To prepare your tooth, your dentist will remove from about 0.3 to 1.2 millimeters of enamel from its surface. Next the dentist will make an impression of the tooth to be sent to a dental laboratory, which will make the veneer. When the veneer is ready, usually a week or two later, you'll need to go back to the dentist to have it placed. To place the veneer, your dentist will first etch the surface of the tooth with a liquid to roughen it. The dentist then applies a special cement to the veneer and places the veneer on the prepared tooth. Once the veneer is in position, your dentist will use a special light to activate chemicals in the cement to make it harden quickly.
