While home oral maintenance is important, it focuses only on areas of the teeth above the gum line. A professional dental cleaning not only cleans your teeth above the gum lines, but also below the gum line. Dental hygienists are specifically trained to remove the plaque and tartar that live in those hard-to-reach places around your teeth. Your regular dental visits should occur every 3-6 months depending on your individual risk assessment. It is important to keep in mind that dental visits do not replace regular brushing and flossing.
