Dental bridges and Partial dentures are used to replace missing teeth, the loss of which might adversely affect your mouth. The negative effects of one or more missing teeth could include the shifting of other teeth, a change in the bite, TMJ disorders, a speech impediment, an increased risk for periodontal disease, and a greater chance of tooth decay.
There are several types of fixed (cannot be removed) bridges. These include conventional fixed bridges, cantilever bridges, and resin bonded bridges.
A conventional and cantilever fixed bridge involves shaping the teeth around the missing tooth. Crowns (caps) are then placed on the shaped teeth and joined to a new tooth (called a pontic) that is used to replace the missing tooth. A resin-bonded bridge, where less preparation of adjacent teeth is required, is often used for the front teeth, providing that the adjoining teeth do not have extensive dental fillings or unhealthy gums.
If you exercise proper dental hygiene, your bridges can last for up to 15 years.
