Upper dentures usually cover the roof of your mouth or your palate. This is necessary so that the denture will have suction and stay in your mouth.
A denture without a palate does not cover the roof of your mouth. It requires implants to stay in place. The teeth snap onto implants.
There are several reasons why someone might choose to get a denture without a palate:
Increased comfort: Some people find not having a palate to be more comfortable.
Better speech: Dentures that cover your palate can sometimes interfere with speech. Not having a palate makes it easier to speak.
Less of a gagging sensation: If you tend to be a gagger, not having a palate could be the answer to increased comfort.
Improved sense of taste and improved sense of temperature. When the roof of your mouth or palate is covered, it becomes harder to taste your food. You can not sense hot or cold as well.
Improved dental hygiene: Because the roof of the mouth is not covered, it is easier to keep your teeth and gums clean.
Reduced risk of gum infections: Without a palate, there is less surface area for bacteria to build up and cause infection.
