Dental Hygienists

Our hygienists are passionate about optimizing our patient's overall health by helping them maintain clean, healthy mouths and beautiful smiles. Oral health is more than having white teeth and fresh breath. For many people, the condition of their mouth mirrors the condition of their body. More than 90% of all systemic diseases have oral manifestations, potentially making your dentist and hygienist the first people to diagnose a health problem. Our hygienists remove bacteria from the mouth before it hardens into a rough, porous substance called calculus (or tartar). Calculus produces toxins which enter the bloodstream through the gums and can cause a variety of diseases that affect the heart, lungs and the intestinal system. Gum disease is linked to heart disease, strokes, oral cancer and pre-term low birth-weight babies.
