5. Drink more water
It may sound simple, but drinking lots of water will ensure you keep your mouth hydrated through the day. Dr. Botchway recommends drinking water with every meal, to help wash everything down. She also suggests sipping on it throughout the day instead of soda (a sugar bath for your teeth!) or caffeinated beverages, which can be dehydrating (coffee and tea can also lead to permanent stains on the teeth). “When our mouth is dry, we don’t have that nice water-flow to wash stuff away,” Dr. Botchway says, explaining that dry tissues are not as healthy, and can allow bacteria to breed.
