Why do Dentures Stop Fitting Well Over Time?

Dentures are a well-known, time-tested solution for missing teeth. When properly made and fit, dentures in Mountain View, CA can be a great answer for dental patients who need them. They help restore your smile, restore the ability to chew properly, help protect jaw bone density and even improve facial structure. However, dentures have a reputation for not fitting as well after a while. What exactly is the reason for this and can it be avoided? Here are some common reasons why dentures stop fitting well over time.

General Wear and Tear

Like anything else, dentures wear down as time goes on. The constant friction, movement and even the process of chewing and drinking can change the physical structure of the dentures in tiny ways that add up. This can make them feel less comfortable or cause slippage.

Weight Fluctuations

While weight loss may be a great thing in the mirror, changes in body weight can negatively impact the fit of dentures. Significant weight gain or loss in particular, can affect the contours of the face and jaw, making it necessary for adjustments or even replacement of your dentures.

Bone Resorption

One of the most common reasons why many people find that their dentures don’t fit as well as they used to is because of bone respiration. This is when the jawbone begins to resorb or shrink due to missing teeth. It’s a natural process, but the consequences mean that your dentures that you loved before, are no longer fitting properly.


As a person gets older, the shape and structure of the mouth and jaw are subject to chance. This is just a natural part of aging, and little can be done about it. Unfortunately, a side effect of this is that it can change the way dentures fit.

Oral Health Problems

Even if you have full upper and lower dentures, your gums still need to be properly cared for. Oral health problems can cause gum disease, which can lead to your dentures no longer fitting the way they are supposed to.

If you have dentures that are becoming uncomfortable or are slipping out of place, don’t delay. Contact your dentist in Mountain View, CA to have them refitted or replaced.
