Modern dental implants have a history of over 30 years, and the data generated worldwide states that 95% of implants can be expected to last for a period of 15-20 years + (accurate data collection started about 20 years ago), and predictions are that 90% of implants should last a lifetime in correct conditions.
Implants are a safe, well-established treatment. It's probably true to say that implants, much like natural teeth, will last for as long as you care for them. How well you look after your implants-and whether you go for your regular maintenance appointments-will have the biggest impact on how long they will last. If you don't look after your implants they will develop a coating similar to what you get on neglected natural teeth. Left untreated, this can lead to gum infection, bleeding, soreness and general discomfort.
