This depends on if you’re talking about the dental implant itself, which is a small piece of metal that’s surgically placed into your mouth, or your dental implant restoration, such as a dental crown to replace one missing tooth.
The dental implant itself will never need to be replaced as long as you take care of your mouth. It’s permanently anchored to your jaw bone due to the process of “osseointegration.” For all intents and purposes, it will become a natural part of your mouth. As long as you brush and floss and see Dr. Miller for an appointment every 6 months, it will never need to be replaced.
However, this is not true of most dental implant restorations, such as dental crowns, implant-supported bridges, and implant-supported bridges. These restorations are subjected to the forces of biting and chewing, and will tend to wear down over time. Restorations like crowns can even break due to oral injuries, or doing something like biting a piece of ice or a piece of very hard food.
This means that, eventually, your dental implant restoration will need to be replaced. The good news is that the process of getting a new restoration is fast and non-invasive, and your restoration will typically last 10-15 years or longer.
