Dental cavities are caused by acid erosion of tooth enamel. Many different types of bacteria normally live in the human mouth. They accumulate on the surface of the teeth in a sticky film called plaque. Plaque forms easily in cracks, pits or fissures in the back teeth; between teeth; around dental fillings or bridgework; and near the gum line. Some of the plaque germs convert sugar and carbohydrates in the foods we eat into acids. These acids dissolve minerals in the surface of the tooth, forming microscopic pits or erosions that get larger over time.
What causes tooth decay?
Poor oral hygiene.
Manual toothbrushes and floss are not the only way to remove the plaque. In fact, automated brushes are one of the most effective ways to break up the plaque build-up on the teeth. Floss can be assisted by various oral irrigators. Styles and kinds of these devices are suggested by doctor based on the individual’s own need.

Dry mouth conditions.
For patients, especially in their 60’s and older could be on multiple prescriptions that slow down or stop saliva flow. Saliva has naturally occurring components that inhibit plaque growth and adherence. Interrupting this process causes decay to appear even on front teeth and can destroy previous dental work.
Tooth grinding and bruxism.
Social and environmental stresses influence tooth grinding. Tooth grinding strips away the hard outer enamel layer leaving the softer dentin exposed.
