Like many areas of the body, our mouth is teeming with bacteria – most of them harmless. Normally the body’s natural defenses and good oral health care, such as daily brushing and flossing, can keep these bacteria under control. However, without proper oral hygiene, bacteria can reach levels that might lead to oral infections, such as tooth decay and gum disease. The health of our teeth, gums and mouth are all connected to the health of the rest of our bodies. Dentists cand catch oral health problems early, before they potentially become painful or costly.
