​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Dental or oral health is concerned with your teeth, gums and mouth. The goal is to prevent complications such as tooth decay (cavities) and gum disease and to maintain the overall health of your mouth.
Good oral and dental hygiene can help prevent bad breath, tooth decay and gum disease—and can help you keep your teeth as you get older. ... An unhealthy mouth, especially if you have gum disease, may increase your risk of serious health problems such as heart attack, stroke, poorly controlled diabetes and preterm labor.
