There are several possible causes for the white, slimy and sticky substance that forms on the inner walls of your mouth.
Though experiencing a white, gooey substance on the inner walls of your mouth is a very unpleasant issue, be assured that the causes are not life-threatening.
“Dry mouth is the most common cause of this unpleasant sensation,” Gary Goldenberg, MD, of Goldenberg Dermatology, and assistant professor of dermatology and pathology at Mount Sinai School of Medicine.
If you find that your dry mouth seems unrelated to dehydration, place a small piece of lemon rind between your back teeth and inner wall of the mouth, and it will stimulate salivary gland production.
Other Causes of White Sticky Substance Inside Mouth
Dr. Goldenberg says, “Medical causes also exist, however. A yeast infection in the mouth can cause this sensation — this is especially common in patients with diabetes and those with very weak immune systems.
“An allergy to a food or your dental filling can also be the cause.”
In addition, certain toothpastes or brands can cause a white slimy substance to form inside of your mouth.
However, this would be an immediate result of using the toothpaste, and it will dissipate as the hours pass.
The solution is to find a toothpaste that doesn’t cause this problem.
