Hi Loretta! Definitely check with your dentist to see if anything can be done about the thickness of the palette of your denture. Sometimes, the palette can be shaved and adjusted to fit more comfortably in the mouth. However, too much adjustment can lessen the suction of the palette to the roof of your mouth, so it’s important that a dentist evaluates the fit. As you get used to your top denture, you may not notice the “thick” feeling as much, as your mouth will get used to the foreign object. Best of luck, and keep us posted on your progress!
