While the life-span of a dental implant is greater than any other tooth-replacement option, its longevity mostly depends on how you take care of it. Dental implants are immune to cavities and other oral diseases, but the rest of your mouth is not. If you don’t properly care for your smile, you may develop gum disease or conditions that might require the removal of your implant. However, if you practice healthy oral hygiene habits, your implant could last for more than 25 years.
