A physician explains where the white slimy gunk on the inside of lips comes from…

Have you experienced a white, slimy, goopy substance on the inside of your lips? 

For this article I consulted with Dr. Stacey Silvers, MD, of Madison ENT & Facial Plastic Surgery in NYC, who is board certified in otolaryngology.

“The slimy substance in the mouth is the oral mucosa that is peeling,” says Dr. Silvers.  “Oral mucosa is like skin cells, will slough off as newer mucosal or skin cells develop.  This can be exacerbated by certain mouthwashes and toothpastes, especially if the toothpaste or mouthwash is in the mouth for an excessive period of time. This is similar to exfoliating the skin.”

If you’ve noticed a slimy white substance on the inside of your lips, switch oral care products and see what happens.

Dr. Silvers says that this problem can also be caused by side effects of certain medications.
