If it's not particularly violent, it's ok to minimize the molar tissue to achieve beauty, but if grinding a lot of tooth tissue is particularly violent, I suggest you don't grind it. If you grind it, you have to make porcelain or telescopic crown to protect your teeth. It is better to correct it or leave it alone! If you destroy your good teeth for the sake of beauty, it's like thinking that someone else's leg looks good, breaking your leg and replacing it with a beautiful prosthetic leg is not as good as your real leg. That's the truth!
If it is a small part of grinding, it has little to do with the regeneration function of dentin layer cells of our teeth. If you want to grind a lot, it will definitely hurt your teeth. It depends! But one thing is certain: grinding teeth is harmful to teeth, just like porcelain is harmful to teeth, but people still won't do it for beauty, that's all!
