Finally, an explanation for what causes that gooey, white, slimy substance inside the walls of your mouth.

As annoying as that white, sticky and gooey substance inside the walls of your mouth is, it’s actually not a medical issue and nothing to worry about.

What causes the white, sticky substance inside the mouth?

“Oral mucosa, like skin cells, will slough off as newer mucosal or skin cells develop,” explains Dr. Stacey Silvers, MD, of Madison ENT & Facial Plastic Surgery in NYC, who is board certified in otolaryngology.

“This can  be exacerbated by certain mouthwashes and toothpastes.

“Especially if the toothpaste or mouthwash is in for an excessive period of time. This is similar to exfoliating the skin.”

If you’ve had the problem of a white, slimy and sticky goop inside your mouth, have you noticed it forms after you’ve brushed your teeth or used a mouthwash?

Switch brands and see what happens. Not all of these products are the same.

An NYC expert in ear, nose and throat care, Dr. Silvers has been named among America’s Top Physicians and Surgeons in facial plastic surgery and otolaryngology numerous times since 2003.
