As an alternative the missing tooth can generally be replaced with a fixed bridge. Healthy teeth must be ground down to fi x the bridge in place. And this means the teeth that are on the left and right of the gap. They act as bridge abutments. The denture is fixed to the bridge with the aid of crowns. The pontic that closes the gap is between the crowns. It is close enough to the jaw bone to look identical to a natural tooth at first. But it does not load the jaw bone like a natural tooth. Because of this the bone atrophies over time like a muscle that is not used and gradually wastes away. This is why bridge components are often clearly visible when people are laughing and talking. Is there no tooth on the left or right because the gap is at the end of a row of teeth? Or a tooth bordering the gap clearly has a limited life expectancy and is therefore not suitable as a bridge abutment? Then there is the removable partial denture. It needs retainers such as small metal clasps attached to the neighboring teeth. However, over time the metal clasps may overload the retainer teeth and cause more tooth losses. This is not necessary — you can have implants.
