The photograph attached to this article provides one of the best true-color images of Mercury that we have. If you could fly over Mercury in your spacecraft, this is essentially what youâd see. The planet Mercury color is a dark gray surface, broken up by craters large and small.
Problems with Dentures Caused by Xerostomia, or Dry Mouth. Dry mouth (also called Xerostomia) in most people is usually a side-effect of medications. Chemotherapy, radiation therapy, and some diseases can also cause a decrease in saliva production. It is necessary to have your dentist find the cause of your dry mouth so you can be treated properly.
Dry mouth can irritate and inflame the mouth's soft tissues, making them more susceptible to infection and growth of harmful organisms. Without sufficient saliva flow, the mouth is less able to clean and shield itself from tooth decay, gum disease and tooth erosion. Dry mouth also can lead to altered taste; bad breath; mouth ulcerations or sores; difficulty in chewing, swallowing and speaking; oral tissue infections and dental attrition and wear.
