What is one potential drawback of using fixed bridges for tooth replacement?

One potential drawback of using fixed bridges for tooth replacement is that they necessitate the alteration of adjacent healthy teeth. When a fixed bridge is placed, the supporting teeth on either side of the gap must be reshaped to accommodate the crowns that will anchor the bridge. This procedure can compromise the structural integrity of those otherwise healthy teeth and may make them more susceptible to future decay or damage.

In contrast, dental implants do not require alteration of adjacent teeth, as they are placed directly into the jawbone. This can preserve the health and function of neighboring teeth, making implants a preferred option for many patients. Other options, such as dentures, do not involve altering adjacent teeth, but they may lack the stability and chewing efficiency compared to a fixed bridge. Additionally, fixed bridges are generally considered more esthetic than removable dentures, and they are also durable when properly cared for.
