Effect of dentures and astringents on palatal mucosa

Continued covering of the surface of the palate results in a progressive regression of the palatal glands. Astringents initiate activity of the glands. Frequent removal of any restoration and rinsing will keep the mucous membrane in a better physiologic state.Rinsing the mouth with an astringent reflexly stimulates palatal glandular activity. This activity and dilation of the ducts cause turgidity within the adjacent tissues. This intrinsic pressure induces a smooth surface of the mucous membrane for the making of an impression.
