Implants (44)

I have one tooth missing.  Please advise on my options prior to my visiting a dentist so that I am fully prepared with another opinion as to how to proceed and maybe I shall choose a new dentist with your help.

My last bridge seemed to lock my teeth together and my dentist recommends that he replace it.  I am looking for a second opinion - are there alternatives to another bridge?

Am I too old at 80 to have implants?  I would rather just have dentures but they move a lot!

Apart from aesthetics, what are the benefits of implants over dentures and is there an age limit to having implants?
