It's not ok to leave the gaps as such. Do take a OPG x-ray and check for allignment of teeth, if it's already upright then u can go in for mild proximal reduction or if not the brackets can be repositioned to close the gaps(which may increase the treatment duration a bit longer). If the gap is less than 1-2mm, then u can try a gingival surgery which can restore the gingival height rather than going for a proximal reduction.
Next Steps
Take a OPG X-ray immediately
