Brace确实挺痛苦的，吃个西瓜都能塞牙缝，说话都困难，睡觉压着脸，铁丝嵌在嘴里，早上起来嘴里都痛，用lip protect嘴就更鼓脸都变形了只能睡觉时候用用，我已经忘记没牙箍是什么感觉了，应该很好吧……

才上一个月，没拔牙，效果....还没看出来5555 我的情况不算复杂，brace价钱便宜才3000多我的保险都报，所以是抱着反正不要钱的心态去的，可现在有点后悔，这几天早上起来牙疼，我觉得之前睡觉有磨牙我自己不知道，戴了牙箍才知道磨一晚早上牙疼

first lets explain what crowding is, which is just your case.
Normally we have 32 permanent teeth, rooting in upper and lower jaws. The size of jaws and that of teeth match and thus teeth are positioned and aligned in the normal way.
If the size of jaws is too small, or if teeth are too big, especially too wide, the jaws cannot accomodate teeth and crowding happens.
Crowding has too basic signs,
1, malposition which means the whole tooth stays out of the line, either close to cheek or to tongue, but still straight up.
2, tipping or rotation.

To relieve crowding, either increase the size of jaws, or decrease the size of teeth, into which your case fell since four teeth have been removed.

Right now you have four empty SPACEs in your mouth after the extractions done. Next step is to align the tipping or rotated teeth that will take some of the available space. This step can be done by invisalign or braces. The space from extraction will become occupied partially by uprighted and derotated teeth and of course will become smaller but still there.
After this step is done or synchronously, all front teeth will be BODILY moved back and the malposistioned ones will be brought back into the line and the rest space will be completely occupied. And, with no space anymore, all teeth are straight up and in position.

It is very difficult if possible for invisalign to move teeth BODILY. It can only finish the last step by tipping teeth backward.
This is why you should go for braces and also the explanation to the part you 不是特别理解.

我用的是fastbraces, 三角形的我觉得比普通的牙箍更鼓，而且疼，不知道是不是心理作用
