Your mouth will be healthier
You’ve been told all along that sugar causes tooth decay. This is because the bacteria that live along your gum line feed on sugar and produce acid as a byproduct. This acid is produced in about 20 seconds and hangs around in your mouth for up to half an hour. During that time, the acid is steadily eroding the enamel on your teeth, causing cavities.
For this reason, sour candies that contain both acid and sugar are especially dangerous. Cutting back on sugar intake makes it much easier to keep your choppers healthy.
