How Long Do Overdentures Last?
For patients looking for a more secure, long-term alternative to traditional dentures, implant overdentures are becoming a popular solution. Overdentures offer improved comfort, stability, and confidence. One of the most common questions people ask before committing to an overdenture as their tooth replacement solution is, how long do overdentures last? If you’re considering permanent or removable overdentures and are curious about their lifespan read on to learn more about them and the factors that influence how long they last.
What are implant overdentures?
Implant overdentures are anchored by dental implants which are placed into the jawbone and act as a stable foundation for the denture. This makes them different than traditional dentures which rest on top of the gums and are not secured in place. Implant overdentures can either snap onto the implants and be removable or be permanently secured in place.
The implants provide stability to the dentures which reduces common issues like slippage, sore spots, and reduced bite strength. Implant overdentures make everyday activities like speaking and eating much more comfortable.
How long do implant overdentures last?
On average, removable implant overdentures last about 7 to 10 years, while fixed implant-supported dentures can last 20 years or more with proper care. The implants themselves, meaning the titanium posts in the jaw, can last a lifetime if cared for properly. The denture, however, may need to be replaced or relined if it becomes worn or damaged over time.
What factors impact the lifespan of the dentures?
There are numerous factors that can impact how long the overdentures last. The most common are:
- Type of Overdenture: The biggest factor affecting how long your overdenture lasts is whether it’s removable or fixed. Removable overdentures, which can be taken out for cleaning and sleeping, tend to wear down faster because of the repeated movement involved in snapping them in and out. Over time, the attachments may loosen or wear out. Fixed overdentures, on the other hand, are locked in place and do not come out. This reduces wear and tear and helps them last longer. Because they function more like natural teeth, they often provide a longer-lasting solution.
- Number and Placement of Implants: Another important factor is the number of implants used and where they’re placed. The more implants supporting the denture, the better the weight is distributed. This reduces stress on each implant and extends the life of the denture. Implants placed at the front of the mouth also tend to experience less biting force than those in the back, which can help them last longer as well.
- At-Home and Professional Care: Good hygiene habits are essential for maintaining overdentures and keeping the implants healthy. Regular brushing, flossing, and professional cleanings will help prevent infections and implant failure. Just like natural teeth, implant overdentures need attention.
What’s the bottom line?
Overdentures offer a strong, stable, and comfortable solution for missing teeth. While the implants themselves can last a lifetime, the denture portion typically needs to be replaced every 7–10 years for removable types and can last 20+ years for fixed options. With proper care and regular check-ups, you can expect your implant overdenture to serve you well for many years.
