"Mask mouth," a play on meth mouth, is spreading like wildfire and dentists are warning that it could have serious consequences, including death.

"Gum disease, or periodontal disease, will eventually lead to strokes and an increased risk of heart attacks," warns Marc Sclafani, a dentist and co-founder of One Manhattan Dental.

Wearing a mask on a regular basis is causing many to experience severe mouth inflammation, the complications of which can be extremely severe.

"We're seeing inflammation in people's gums that have been healthy forever, and cavities in people who have never had them before," adds Rob Ramondi, another dentist and One Manhattan Dental co-founder.

According to Ramondi, roughly half of his patients are suffering from health problems due to wearing a mask.
