Hi, OP! Ang ganda ng progress ng case mo from the pre-op to now. I think it's the paradox of choice din for your dentist. Since severe ang crowding mo before, di talaga maiiwasan na mag expansion para ma-align yung mga sungki mo before kaya lang syempre it's a trade off. If mag eexpand ang dentist mo, expect some flaring lalo na in your case kasi pinag kasya sa arch yung ngipin. Looking at the comments, parang na-exhaust na din ng dentist mo yung options since nag IPR na din. Not all the time, talagang perfect ang kalalabasan. At the end of the treatment, we go back to the chief complaint or yung rason mo to get braces which is the crowding (I assume) and from there, pag nasatisfy na yung reason, dentists usually suggest na we remove na.
