A dental implant is considered a durable, long-lasting tooth replacement option - as long as they are properly cared for with an intense at-home oral hygiene and trips to the dentist for regular checkups.  Whether they are attached to natural teeth or dental implants, it's also true that tooth replacements such as crowns, bridges and dentures can become stained, cracked, chipped, loosened or otherwise damaged. Issues can also occur with the underlying luting cement, abutment or the tooth replacement itself and lead to problems.  Your dentist can assess these, then create a custom treatment plan to correct any issues.
