What Causes Implant Overdentures to Break?

Implant overdentures provide a secure, comfortable solution for replacing missing teeth, but like any dental appliance, they aren’t indestructible. Over time, they can crack, chip, or even break completely. If this happens, repairs or replacements may be necessary. Understanding the causes of breakage can help you take the right steps to prevent damage and extend their lifespan.

1. Excessive Force from Biting or Grinding

One of the biggest threats to implant overdentures is excessive pressure from clenching or grinding your teeth. Over time, this can cause cracks, fractures, worn down areas, or even loosen the attachment points. If you have a history of grinding, a custom nightguard can help protect your overdentures.

2. Poor Fit or Misalignment

If an implant overdenture doesn’t fit correctly, uneven pressure can weaken certain areas and lead to breakage. Regular dental checkups allow your dentist to adjust the fit as needed, preventing stress on the dentures.

3. Wear and Tear Over Time

Even high-quality overdentures wear down with daily use. The materials used to create the denture base and teeth can become brittle or weak, increasing the risk of cracks or fractures. Most implant overdentures last 7–10 years before needing replacement.

4. Damage to the Attachment System

The clips, bars, or locators that hold the overdenture in place can loosen or break, making the denture unstable. If the attachments aren’t functioning properly, the denture may shift and crack. Routine maintenance helps keep these components secure.

5. Accidental Drops or Impact

Dropping your overdenture on a hard surface can cause chips, fractures, or even complete breaks. Handle them carefully, and always place a towel in the sink when cleaning them to cushion accidental falls. Avoid using your teeth as tools to open packaging or crack nuts.
