You may feel discomfort after having a porcelain crown, but the discomfort will gradually improve in about 2-3 months. The main reason is that there is still a difference between a porcelain crown and a natural tooth, and the tightness of the neighboring space and the state of the bite need to be gradually adapted by the patient. The smoothness of the surface of porcelain crowns is also different from that of natural teeth, and after a 3-month adaptation period, patients will not feel much difference. When using porcelain crowns, it is important not to use hard foods, such as peanuts or cartilage, as this may cause the porcelain layer on the surface of the crown to chip. Porcelain crown life is about 10 years, 10 years after the need for replacement, and porcelain crown fit is very important, if there is an ectopic situation in the mouth, you need to find a doctor in time to observe how the fit is, to protect the inner abutment teeth.
