You may hear a radio ad that talks about "permanent" teeth or "permanent" dentures.
Permanent is a very strong word and may not be completely true. It may be a marketing tactic only.
A major implant manufacturer even says it!
Dental implants are fantastic, and they are the closest thing to being "permanent." Dental implants are the best tooth replacement option available. The implant is the part that goes in the bone, but either porcelain teeth or dentures have to be attached to them.
Permanent dentures do not exist. The overdenture that is made on top of the implants will wear out just like any other denture will. The teeth on dentures are plastic, so they do wear out every few years and need to be replaced. Porcelain teeth whether they are made as a crown on your natural tooth or on an implant can chip or break necessitating its replacement.
Don't get me wrong…dental implants are the best, but don't let someone tell you that the teeth are the last ones you will ever have. I would be very leary of a dentist in Burbank, Glendale or South Africa for that fact who said dentures or implant teeth are "permanent."
You should be aware of the real and honest facts that implant teeth may need to be replaced…especially dentures.
Bottom line: The implants in the bone are not replaced often, but the teeth on top of the implants can require maintenance, repair and even replacement.
