Dental cleaning is the removal of tartar and plaques from your teeth and gum lines, thereby reducing inflammation and improving the health of your gum. Plaques are sticky film that forms on the teeth which contain bacteria and develops when food mixes with saliva. However, plaque accumulation can lead to gum disease, including inflation of gums, also known as gingivitis. If you do not treat gingivitis, they can advance to periodontitis. Periodontitis is a severe infection that destroys the bone that supports the teeth.
