It’s always a good idea to replace missing teeth. If you’re missing even just a single tooth, it can cause your other teeth to shift into different positions in order to fill the gap left behind by the missing tooth. That can throw your bite off and lead to a variety of other issues. Fortunately, there are several ways to replace one or more missing teeth. One of the most popular options is a dental bridge. These appliances consist of one or more porcelain crowns mounted onto a metal frame. Brackets on each end of the frame fit securely over the patient’s remaining natural teeth on each side. Because the crowns used in bridges are made from porcelain, they are not only virtually undetectable by other people; they also last for many, many years.
