A bridge cannot be removed from your mouth for cleaning as it is permanently fixed in your mouth. The majority of bridges are made by putting crowns on the teeth at either side of the space and then joining these two crowns together by placing one or more false teeth in the space.
Another option is an adhesive bridge, which is bonded to the back of supporting teeth with very little drilling involved.
Bridges are only possible if you have enough strong teeth with good bone support. Your dentist will help you to decide which is best way of replacing missing teeth.
