When you still had your original teeth the daily act of biting, grinding and chewing acted to stimulate the bones beneath your gum structure. This encouraged your body to maintain a modest level of structural integrity.
When your natural teeth were removed to make way for your complete dentures, this bone structure was also affected. Over time the lack of natural stimulation can cause your body to absorb some of the bond structure in your jaw.
This gradual process of oral atrophy can alter the shape of your jaw structure, causing the dentures to fit feel increasingly loose. At first, you might be able to lock your dentures in place by applying a little extra denture adhesive. This will help to ensure the tight bond that you appreciate, while also keeping stray food particles from irritating the gums at the base of the dentures.
If you do have a little bit of stray food matter work its way into the area you should rinse your dentures clean. You should then dry the base thoroughly with a napkin or a clean paper towel before applying a fresh bead of denture adhesive.
