It is difficult to give an exact answer to this question, as the longevity of a dental bridge will vary depending on a number of factors, including the specific tooth that the bridge is attached to, the dental technique used to create the bridge, and the individual’s oral health and diet. Generally speaking, however, dental bridges typically last anywhere from six to twelve years. If any of the dental crowns or bridges begins to deteriorate, or if the individual experiences any problems with their teeth or gums, they should always consult a dentist or dental specialist for guidance.
