Hi Jillie,
Sorry for the slow response, but computer issues have kept my activity at a minimum the past few days.
Is your daughter thal minor? Did she lose much blood during the wisdom teeth removal? Was there any infection afterward?
Vegetarianism would definitely not be responsible for her mood changes, nor would taking supplements. If there was a lack of oxygen during the procedure, it could cause some problems, but I am wondering if anything happened during the procedure that may have had a traumatic effect.
