Your situation is very common. First of all we will do everything possible to help you keep your remaining natural teeth as long as their supporting structures are within an acceptable range. Supporting structures means the gum and bone tissues immediately surrounding the tooth. A thorough evaluation must be made to determine if a tooth is healthy enough to keep or not. We do not want remaining unhealthy teeth to compromise the success of any new treatment performed whether it be dental implants or other treatment. We must then decide what is best for your specific needs in order to restore your missing back teeth. If you have had problems with removable partials, then dental implants used to anchor new replacement teeth may be the best answer for you.
