Like other kinds of dental implants, those used in an All-on-4 procedure can last decades, or potentially for your lifetime. The restorations attached to your implants, however, will likely require replacement at some point. With care, your new teeth can last a decade or more. You can extend their life by taking good care of them. That includes following good oral hygiene practices, visiting us at least twice a year for checkups, and making positive lifestyle changes such as stopping smoking.
