If Dental Implants last 15 years. What happens after that?

http://www.kentsmilestudio.com/dental-services-kent/kent-dental-implants/ Dr. Dattani explains: The research is always done for 15 years. Nobel Biocare are actually proud and have actually done research for 25 years as well. It’s, they should last much longer but we can’t quote it lasting much longer because the evidence isn’t there. What can happen after time, as our teeth and gums recede, the gums round the implants might recede so there might be a cosmetic problems where you might see some threads of the implants, which would later need covering up. If someone’s medical health was suddenly to change that could be an argument why suddenly the integration, that’s the glue, can suddenly go, but that evidence is still yet to come out. Worst case scenario if an implant does fail, say early on, to replace it with another implant might need additional procedures.
