Tooth Decay Tooth decay is the destruction of the enamel (outer surface) of a tooth. Tooth decay is also known as dental cavities or dental caries. Decay is caused by bacteria that collect on tooth enamel. The bacteria live in a sticky‚ white film called plaque (pronounced PLAK). Bacteria obtain their food from sugar and starch in a person’s diet. When they eat those foods‚ the bacteria create an acid that attacks tooth enamel and causes decay. Tooth decay is the second most common health

different types of force characteristics such as heavy versus light forces and continuous versus intermittent force and the type of tooth movement influence the rate and force of orthodontic tooth movement. Heavy forces generally results in pain development‚ necrosis of cellular components within the PDL and undermining resorption of alveolar bone adjacent to the affected tooth (Proffit‚ Fields‚ & Saver‚ 2013).

compound. Fluoride is effective in preventing and reversing the early signs of tooth decay. Researchers have shown that there are several ways through which fluoride achieves its decay-preventive effects. It makes the tooth structure stronger‚ so teeth are more resistant to acid attacks. Acid is formed when the bacteria in plaque break down sugars and carbohydrates from the diet. Repeated acid attacks break down the tooth‚ which causes cavities. Fluoride also acts to repair areas in which acid attacks
