Why do I need to visit the dentist twice a year?
Even if you are diligent about home care and brushing and flossing after meals, a toothbrush can't get to all the areas in your mouth where plaque can develop. This sticky substance builds up over time and turns into a hard substance called calculus. Calculus (also known as tartar) can only be removed with special dental tools.
Visiting your dentist every six months also enables your dentist to discover problems early, when treatment is generally easier and less expensive.
