First of all, porcelain teeth are the general name of all porcelain crowns, including all-ceramic crowns and metal porcelain crowns.

The first choice for posterior teeth is pure metal casting crown, but some patients find it ugly, so they have to choose porcelain crown as the second best. The posterior teeth can choose zirconia crown (all-ceramic crown) or any kind of metal porcelain crown at will. After all, it is recommended to use supragingival shoulder platform for posterior teeth, and the edge of porcelain crown does not release from the gum, so the gum problem that many people are worried about is actually easy to solve.

As for the choice of single crown and continuous crown, of course, it is necessary to choose single crown as far as possible. The significance of single crown is that it is beneficial to the physiological mobility between teeth and better discharge food debris.

Toothache can only be treated with porcelain crown after good root canal treatment. Porcelain crown can not solve toothache, but can only protect teeth in the later stage. There is nothing to pay attention to in life. In fact, it is mainly to pay attention to cleaning and avoid trauma.
