While the life-span of a dental implant is longer than any other tooth-replacement option, its longevity mostly depends on how well you care for 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 good oral hygiene habits, your implant could last for more than 25 years.
