Wearing a face mask can give you bad breath and even cavities in your teeth, leading dentist warns people in Milton Keynes

But the answer could be as simple as chewing sugar-free gum under your mask, says Dr. Jeffrey Sulitzer, who is Chief Clinical Officer of SmileDirectClub .

He says many dentists globally have coined the term, "mask mouth" because of the impact face masks can have.

“Covering your mouth and nose for long periods of time impacts your breathing and forces you to breath more through your mouth," he told the Citizen.

"As a result, this restricts the flow of moisture which can cause dryness in your mouth. A dry mouth has the increased tendency for cavities, gum disease and bad breath."

Dr Sulitzer suggests: "If you’re wearing a mask for long periods of time, you should enhance your normal oral hygiene program, hydrate between wearing masks, and try using sugar free lozenges or gum to promote salivary flow.”
