A dry mouth isn’t just unpleasant, it’s bad for your teeth. Saliva washes away cavity-causing bacteria and neutralizes harmful acids.
“Without saliva, you would lose your teeth much faster—it helps prevent tooth decay and other oral health problems,” says Meinecke.
Drink lots of water, chew sugarless gum, use a fluoride toothpaste or rinse, and consider over-the-counter artificial saliva substitutes. See your doctor if it’s a frequent problem.
