When i wake of a morning my teeth and inside of my mouth are coated with plaque i am assuming. I floss and use a Sonicare toothbrush, go to the dentist every quarter and have no gum disease or cavities, I have porcelain fillings. What is causing this large amount of plaque? Does this mean my arteries could have plaque? My age is 67, 5 6 , weight 150. Good health. Take no prescriptions just vitamins.
