Absolutely. In fact, more dentists should advocate for the use of dental implants over dentures in elderly patients. There is no difference in the success rates in younger versus older folks. The healing process is the same. One is never too old to undergo this treatment as long as they are in good health condition and not experiencing any medical issues that may create an obstacle for the implant placement.
In order to determine whether you make a great candidate for the procedure, you should have a consultation with someone experienced and certified. They will answer your questions and evaluate your suitability. If you have any existing dental issues that need to be fixed, they may have to be attended to first.
