As a dentist, I am asked to repair damage to teeth. The forces of infectious microbes cause terrible destruction to our teeth and gums.
Let's just look at the teeth for now and think about what happens when we consume sugar too often in our diet. Placing sugar in the mouth too often can make a cavity. Here's how:
Invisible and seemingly safe BACTERIA are everywhere and because of their immense numbers they frequently end up in the human mouth. Here they find a warm, moist, dark place to settle and when fed a diet of easily absorbed simple carbohydrates (SUGAR) they thrive and multiply in their new found home, their ACID waste products literally dissolve the tooth and make cavities.
This whole nasty process can be blocked and reversed by our first line of defense, our SALIVA. This secretion ideally formulated to stop the bacteria, neutralize their acid waste and rebuild (remineralize) the tooth. The saliva's rebuilding process begins as soon as we start eating or drinking and continues several hours after the acid is formed, reversing the tooth decay and presenting a strong healthy tooth again.
Time is what the saliva needs and a lack of time cuts short the miraculous repair and healing that is needed to keep the teeth strong. When we eat sugar too soon or wash away the saliva before the process is complete, the breakdown of the tooth continues. Remember, saliva is not water. It is a special secretion produced by the body to rebuild the tooth. Water washes it away. The time needed here is generally two to three hours, time we can give the mouth by merely leaving it alone to do it's work. I call this the THREE HOUR RULE (no sugar or water for 3-hours).
Please remember this process is going on in a microscopic arena, much too small to see. It is a story that needs to be told so we can avoid tooth decay and the life-long damage it causes.
