2 children (ages 7 & 8) with extensive cavities were treated by Dr Watson. She left root tips in on one extraction which later became infected and needed to be surgically removed. 1 filling is the first child and 2 in the 2nd were so poorly done (decay left behind, poorly sealed) that absesses developed resulting in an extraction and 2 pulpectomies (by a DIFFERENT dentist). She should have done pulpectomies in the first place, but didn't.
