Patient: There are white spots on the outer side of the tooth (seems to be calcification) that I thought could be removed by scaling, but the doctor said the other day that the tooth was not well nourished and could not be removed (it was not). Is there any way to restore the nutrition and make the white spots disappear (the middle of the white spots already has a small cavity)? Laboratory and examination results: Last seen at: Yuyao Second People’s Hospital Guangzhou Medical College First Affiliated Hospital Stomatology Department Pan Guangshi: The situation you described is the phenomenon of tooth decay process, clinically called early caries —- shallow caries, that is, the decalcification area (white plaque) appears first in the plaque attachment area, and then the cavity appears, can’t get better by eating or taking medicine, should immediately consult for filling treatment Patient: En , I want to ask what is the difference between early filling and late filling ah? Because according to my filling experience, the price of a tooth is the same no matter how big the hole is, as long as it can be filled, and a big hole has to be ground out to be filled. I am afraid of pain! For such a small shallow cavity, it is not justified to give anesthetic injection! If I can reduce the pain by filling it early, I will go immediately, if it is the same, I am still a little afraid to fill it! (Not even a total of 6 pieces, I’m afraid to fill!) Pan Guangshi, Department of Stomatology, The First Affiliated Hospital of Guangzhou Medical College: The damage scope of early caries is small, and the scope of doctor’s grinding is also small, besides, the shallower the hole, the less painful it is, if the treatment is too late, the caries will reach the pulp, the pain will be more serious, and more complicated endodontic treatment may be needed. So it should be treated as soon as possible Patient: I know, thank you, then I will go to fill it as soon as possible!
