<s>[INST] 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. [/INST] Hi,Thanks for posting the query,     No this does not mean that your artries are ahving plague, i would like to tell you that plague is a sticky substance which is formed in our mouth due to food particles, saliva present in the mouth this substance gets tenaciously adherent to the tooth surface and fixed prosthesis, i would suggest you to brush your teeth at night before going to bed and get complete mouth scaling and polishing done once in every six months.Take care! </s>
