But don’t be alarmed, it’s normal! Bacteria is present in your mouth at birth and will be present for life! The bacteria in your mouth feeds on carbohydrates. When the interaction of bacteria and sugar causes fermentation, the result is Acid. Acid attacks the enamel of your teeth and surrounding gums, robbing it of minerals. Repeated cycles of acid attack can result in a cavity. Acid left undisturbed around the gum tissue produces toxins that cause gum disease. Excellent home care will help clear the mouth of these harmful acids.
