I'm straightening my teeth, and the doctor advised me to have my teeth pulled out. But some people say that tooth extraction will hurt my nerves, leading to loose teeth in the future. Is it really harmful after tooth extraction? Most people have to pull out their teeth to correct their teeth. I also asked the doctor before pulling the tooth. The doctor said that teeth are connected with nerve endings, and the effect of tooth extraction on nerves is very small and can be ignored. Tooth extraction will not cause tooth loosening. However, after orthodontic treatment, the risk definitely exists. Because you will exert force on your teeth when correcting, healthy teeth will be pulled by the outside world. It will affect its firmness more or less. But on the whole, the problem is not big. After correction, you may feel that your teeth are not as tight as before, but after a while, your teeth will return to normal. As long as you pay attention to using your teeth in the future, there will be no problem. Of course, no matter how you maintain it, it is inevitable that your teeth will loosen when you get old.
