bridge is made of several crowns
connected to each other in order to replace one or more missing teeth.
Bridges help prevent shifting and tilting of the remaining teeth after
one or more teeth are lost. The procedure and materials are identical
to crowns. Bridges are permanently placed and are not removable as dentures
Crowns (also called caps) are a tooth like covering used to restore and support teeth, and help you maintain a balanced occlusion.
Crowns are placed over teeth similar to how a thimble fits over a finger.
Crowns are placed if the tooth is fractured, if there is an existing filling that covers more than half of the tooth, after a root canal is done, or to change the shape, size or color of a tooth.
Crowns can be made from non-precious metals or gold, a combination of metals with porcelain, or from pure porcelain. The choice of materials depends on your preferences and your dentist's recommendation.
Crowns are generally completed in two visits. On the first visit, the tooth is sculpted into a specific shape, an impression is made and a temporary crown fabricated and placed over the tooth. The impression is sent to a dental lab where the actual crown is custom made for every case. On the second appointment, generally two weeks after the first, the temporary is removed, the tooth cleaned and disinfected, and the permanent crown is cemented.
After a few days, the crown should feel similar to a real tooth. Remember, it is possible to develop cavities around the margins of a crown. Brushing, flossing and regular dental checkups are all the care crowns require to continue functioning for many years.
