Are your dentures not as comfortable as they were when you first got them? Maintaining regular checkups with your denturist is essential to keep your dentures in top shape. If your dentures become loose, they can cause irritation that can lead to sores and infection. When your dentures do not fit properly, they can chafe the gums, causing irritation. Tissue irritation can make your dentures so uncomfortable, it’s practically impossible to wear them because of the pain. Always practice good oral hygiene habits like removing your dentures every night and using a soft-bristled brush to brush your gums, tongue, cheeks, and the roof of your mouth.
