Why Are My Dentures Sliding Around?

Posted in Dentures

You’ve had your dentures for several years. Just when you’ve (finally!) gotten used to them, they’re suddenly loose and unstable. What happened?

Here’s a hint: it’s not your dentures that have changed!

First off, let’s review how your denture was made. Your denture is probably a solid piece of acrylic. It was designed from an exact mold taken of your mouth. The denture reflects every contour and ridge in your mouth. So how your mouth looked and felt at the time your denture was made is exactly how your denture will stay.

Changes in Your Mouth

The bone under your gum tissue is dynamic and pressure-sensitive. Teeth can move through bone. In fact, the pressure of a tooth nested within the bone encourages it to continue a healthy cycle of wear and reinforcement.

What if you have no teeth left to stimulate the bone?

The ridge of bone underneath gums can gradually resorb and weaken. As this happens, the height and shape of your smile will change. Your perfectly matched denture is no longer a perfect fit!

A well-fitted denture doesn’t usually need much help to stay in place. If you find yourself reaching for a denture adhesive after several years of use, then that’s a sign that your mouth has changed and needs a new fit.

How to Fix Loose Dentures

The surest, safest, and most permanent solution for loose dentures is to bring them in to your dentist.

Depending upon your individual needs and circumstances, your dentist may recommend:

  • Relining
  • Rebasing
  • A new denture

If your denture is slipping around more than usual, it could be time for a checkup!
