The etiology in regards to dental decay is multifactorial, however in a simplified description, bacterial digestion of refined carbohydrates creates an acidic environment that “eats through” the enamel. Once the decay reaches the softer dentin, it can spread rapidly. Preventive methods should include proper brushing (particularly at night) and flossing to remove plaque between the teeth. Utilization of an oral irrigator (again, especially before going to bed) is very helpful in washing out entrapped food particles.
