A bridge, also known as a fixed partial denture, is generally attached to two teeth on each side of the missing tooth. They are most commonly used to replace one or more missing teeth. Bridges can be permanent or removable. If a patient has missing teeth, this can cause several problems that bridges can help prevent, such as a bad bite, gum disease, and tooth decay. Also, bridges can improve your smile, giving you a beautiful appearance that can last up to ten years or more with the correct care.
