Earlier, dentures used to take time to settle in the mouth and used to not look like natural teeth. But with recent advancements in dental materials, dentures have become comfortable and natural-looking than ever.

How does food accumulate in dentures?

Food particles in the mouth tend to move around and cling on to the surface of the teeth or any foreign object in the mouth. Often, dentures become the prime center for food accumulation. (2)

So how does the food accumulate in dentures?

  • The food particles may drift to the floor of the mouth and accumulate under the lower denture
  • The chewing motion often pushes the food particles forward and backward

  • The rough surface of the denture allows the food particles to stick to it as compared to other oral tissues. This allows the build-up of food and plaque over time.

Dentures take support from the surrounding oral tissues. They occupy a fair amount of space in the mouth. Hence, a person with dentures is more likely to accumulate food particles as compared to a person with natural teeth.
