1. They Slip and Slide
One of the most crucial signs that you need new dentures is if they’re slipping and sliding around in your mouth. Slipping and sliding is a sign that your dentures don’t fit correctly. Over time, your gums will shrink as your jaw bone resorbs. As they shrink, your dentures will become looser and feel too large for your mouth. Then, whenever you eat or talk, your dentures might slip and slide around in your mouth. It can make simple activities like smiling, eating, or talking feel embarrassing.
