What is the pain under the right side of the nose? I did six front incisors, when I did porcelain teeth, he said it would take a while to come back, because the glue is not very long (not the last glue), and the tooth is not beautiful, porcelain teeth place wired gray gap, but almost half a year, it still did not fall off, every time I said it could not get down, said too tight, how can I make it fall off, stick the last time that glue, the gray gap on the teeth will be gone! I’m sorry. Doctor: Hello: porcelain teeth if the adhesion is not very firm and the crown and your real teeth are not very close together, then with special tools can be removed. If you can not take down can only be destructive to take down (that is, the crown destroyed and then take down). In addition, there are many reasons for the gray gap on the porcelain teeth, we recommend that you go to the hospital, according to your specific situation before treatment.
