👄 Why Do Dentures Make My Upper Lip Stick Out?
When dentures are not fitted correctly they can push your upper lip outward. This can happen for several reasons:
1. Lack of Lip Support
If your upper denture lacks proper lip support the upper lip doesn’t have a base to rest against. This causes it to stick out even when your mouth is relaxed.
2. Denture Too Thick or Teeth Too Big
Overly thick dentures or false teeth that are too big create pressure from inside the mouth, forcing the upper lip forward. This is one of the most common causes of the monkey mouth denture look.
3. Flat or Incorrect Bite Design
If the occlusion (bite) is wrong the top lip may stick to the teeth or fail to move naturally when you smile.
4. Thin Upper Lip Appearance
Some dentures pull tissue inward giving you a thin upper lip which makes the lip line disappear or look compressed from the side profile.
