Why are my dentures loose?

Dentures or partials are an option for tooth replacement. It is important to properly maintain your dentures and visit your dental professional for regular check-ups. Dentures should fit snugly on the gums without putting too much pressure. There should be enough suction to keep them in place, but they should not be difficult to remove. Partial dentures should align with your natural teeth.


In some cases, the denture might become loose even with proper care. Poorly fitting dentures could cause sores, infections, difficulty speaking and chewing, and may even come out of your mouth unintentionally. Here are some of the most common reasons for loose dentures:

  • Bone resorption: Loss of your jawbone, or bone resorption, is the most common reason for loose dentures. When teeth are missing, your bone and gum ridges start to shrink due to the lack of stimulation from the tooth roots. Also, over time your mouth naturally changes, which can change the fit of the denture.
  • Wear and tear: Your denture will get everyday wear and tear. Don’t soak your denture in hot/boiling water, as this can cause the denture to distort. You will want to be gentle around partials with clasps. Don’t use cleaning solutions that are too abrasive. You might also cause wear eating foods that are hard or chewy. Try to take smaller bites, and chew on both sides of the mouth.
  • Poorly fitting dentures: After getting new dentures, it’s important to let the dentist know if something doesn’t feel right so adjustments can be made.

When dentures or partials feel loose the best option is to visit your dental professional to evaluate possible causes and solutions. Your dental professional may recommend denture adhesives if they are slightly loose. This can provide stability and hold them in place, allowing you to eat and speak without your dentures slipping, sliding around, or falling out.  If they are significantly loose you may need an adjustment or even a replacement to ensure the best fit.
