since i haven't gone to see the dentist for two years ( i hate dental work), Once the gum line grow back, some of the plaques are under the gum meat now. the dentist wanted to clean the part of the teeth was wraped up by gum , so he had to do local anesthesia and cut into gum and do deep cleaning rather than regular cleaning, so i had three cleaning done in one month, one performed by a regular hygienist, later two were performed by the dentist.
i just started to learn 中医, that's my understanding so far, for me,中医,is more the way of living healthy life more than taking chinese medicines like insects and herbal soup, if you are interested, read chen yu qing's ariticle, she explains very well.
上医医末病,中医的最高境界, that means healthy life style and 用经络帮助身体健康
