People with bruxism grind their teeth, which wears down the surface. Once tooth wear progresses through the enamel layer, the exposed dentin layer is softer and more vulnerable to wear and tooth decay. The image shows anatomy of human tooth decay and tooth loss. Tooth decay is the breakdown of teeth due to acids made by bacteria. The bacteria present in the mouth, acid formed by them, food debris left, and the saliva in the mouth combines to form plaque that sticks to the teeth. Presence of acids in plaque dissolves the enamel surface of the teeth and leads to the formation of holes in the teeth which are referred to as cavities.
