After wearin braces is it normal to have spaces? :(

Not ideally, but...: Every case is different. It depends upon many factors. An orthodontist cannot always achieve a 100% ideal occlusion, depending upon jaw and tooth harmony, patient cooperation, etc. Slight spaces can often be resolved with adjustments using the final removable retainer. This is an issue that you should discuss with your own orthodontist who is most knowledgeable with your case.

Possibly: There is almost always residual band space between the back teeth that will close over a couple of months. Sometimes it is not possible to close some spaces, i find a space will remain between the upper lateral incisors and cuspids at times. Discuss with your orthodontist you r particular issues.

Not unless planned: Unless specific spaces were planned to held open, the answer is no.
