Bacteria that populate the mouth metabolize simple carbohydrates (sugar) and produce the acid that causes tooth decay. Reducing the bacteria by effective and frequent brushing and flossing can reduce tooth decay. Limiting intake of sugar will also reduce decay. There is also a growing body of research that indicates xylitol as a sugar substitute may also be effective in reducing tooth decay.
Tooth decay is the process that results in a cavity (dental caries). It occurs when bacteria in your mouth make acids that eat away at a tooth. If not treated, tooth decay can cause pain, infection, and tooth loss. The mixture of bacteria and acids make a sticky substance called plaque which if not treated, can cause your tooth to rot or turn into a yellowish colour.
