Patient: Hello doctor, I would like to ask the porcelain tooth removal on the real teeth? Doctor: There may be a little damage to the abutment teeth in the process of removal, but the damage is not significant. Patient: Thank you, I have another question: I now have a single porcelain teeth, four front incisors, nickel-chromium porcelain, wear 5 years, but has been feeling less satisfied with the color and shape, and now the upper edge of the tooth also appeared a black edge, want to remove redo, our side of the dentist said, after removal, it is possible that the original porcelain teeth, so many years may occur loosening or corrosion, it may be necessary to I would like to ask Dr. Shao, will this really happen? Doctor: Because no one knows what kind of situation the abutment teeth (teeth wrapped by porcelain crowns) are in before removal, it is possible to find out that they are very bad or have to be extracted after removal, if this is the case, it is possible to do one to two more teeth. Of course, if loosening or erosion occurs, there is a possibility that you will need to do a connecting bridge of sorts. Your primary care doctor made a good point in telling you what is possible before removing it, I think this doctor is serious about seeing patients and deserves to be trusted. Patient: In that case, it is better not to remove it, right? I would like to hear your advice. Doctor: For this issue, I am neither for nor against, depending on your aesthetic requirements and the condition of your teeth. Patient: My current porcelain teeth do not feel bad at all, there can be “removed after the bad or to remove” the possibility of? What are the chances of that? Can I know the condition of the abutment teeth (teeth encased in porcelain crowns) by taking dental radiographs? Doctors: It is possible that “the tooth is very bad after removal or has to be extracted”. It is difficult to check by taking dental radiographs. Yesterday, a female comrade because of apical infection, need to remove the crown, from the x-ray can not see anything, but after removing the crown found that the inside are rotten, can not stay, and finally extracted.
