Should I take off the rubber ring on my braces when I sleep?

That rubber ring should be a leather case. Wearing it can make the teeth move to the target faster, but wearing teeth is also more painful. Can't pick it. This is just to correct. This is a gradual process. You can't play its due role when you take it off. Hang in there. You have to pay before you report. But it doesn't fit. If you really feel uncomfortable, you can find a doctor to change it.
