There is a struggle between acid-creating bacteria in the mouth that cause cavities and the pH-lowering saliva that can keep the acid in check. When a person gives that oral bacteria a diet of sugar, the result is a bacterial feeding frenzy that overpowers the saliva and causes tooth decay.
There are things that can be done to prevent this destructive cycle. First, there is regular brushing, flossing, and semi-annual dental visits. However, patients should also read their food packages carefully and limit foods containing sugars and syrups. Sugar is an additive in MANY foods! Try to limit the intake of anything that ends in “-ose” (sucralose, fructose, dextrose …).
