A: Never grind your teeth! Enamel is the hardest protective layer of teeth. If it is worn thin, bacteria can easily enter the teeth, and the probability of tooth decay is particularly high. Don't use this method of grinding your teeth unless you have to, it hurts your teeth too much.

If you don't grind your teeth and pull out your teeth, you will pull out the upper and lower four teeth together, but pulling out your teeth will lower the height of the lower third of your face a little bit, just as the distance from the tip of my nose to my chin is much shorter than the previous two points. Wouldn't it be shorter to pull out your teeth?

A: Compared with grinding teeth, this method can protect your other teeth to the maximum extent. Theoretically, the lower third will be a little lower, but it is almost undetectable. Moreover, the next third of China people have relatively short faces. So you don't have to pay special attention to this; Take tooth extraction as an example. I am also worried about whether the joint responsible for opening and closing the mouth (we call it temporomandibular joint) will have any influence. This requires you to go to a regular stomatological hospital, take a lateral head film, and combine your teeth and joints to draw a conclusion. Therefore, I suggest you change hospitals and find a more responsible and trustworthy doctor. It takes several years to straighten teeth. If you don't trust your dentist at first, you will be in fear for the next few years, which will also affect the correction effect.

I wish you and your family happiness and health o(∩_∩)o
