I had 4 implants replacing just over a quarter of my mouth in October 2021, when aged 64. After extracting some teeth he put me on a weeks antibiotics to reduce the chance of picking up an infection. I paid for a temporary denture, rather than walk around with a big gap and talking weirdly. The Dentist wanted me to wait 6 months for the jaw bone to strengthen before completing the work. For me it was well worth doing as it replaced a slipping denture and the implants will chew through any food easily. They actually feel so more secure than my remaining teeth and bridge. I will probably get my other bridge replaced within the next 2 years.
Depends if you have problems now. If it was an issue you feel is affecting your quality of life, I would get it done, even at your age, presuming money is not an issue.
