It is very difficult to recommend any treatment based on a photo. The only way a proper treatment plan is designed is when you speak to your dentist, define your priorities and they look at finances.If you are looking for an expert opinion, talk to a Prosthodontist, who is the expert in restorative, cosmetic, and implant dentistry.

If your teeth are already compromised and were carrying a bridge for 15 years, then separating them and using an implant to replace the missing tooth, contingent of bone availability, is a far better option.
