There are plenty of published studies relating poor oral hygiene to heart disease, kidney problems, low birth weight and premature deliveries. If you value your health, have your teeth cleaned 3 times a year and brush and floss several times a day.
If I were a cardiologist, I would demand that my patients have 3 cleanings a year WHETHER OR NOT THEY HAD DENTAL INSURANCE.
Brush and floss to save your heart.
