Many artists in the entertainment circle have made porcelain teeth. As a public image, they may not want others to say that they have yellow teeth or ugly teeth, so they choose to change their image. It is said that Yang Mi also made porcelain teeth. Yang Mi's face has changed a lot and her face value has improved a lot.
In an interview, Yang Mi said that in order to make a movie, he pulled out four of his lower teeth. No wonder Yang Mi is so popular. It's also hard to sacrifice four teeth for your own movie.
However, tooth extraction is symmetrical up and down, so it is impossible to choose only tooth extraction or tooth extraction. This is a very unscientific behavior. Even if Yang Mi only pulled out the lower teeth, there should be more than six. If four teeth are pulled out, there are eight left.
Yang Mi doesn't have back molars when he smiles because of the porcelain teeth, which are too white to cover up the color of the back molars, so it seems that there are no back molars.
