I had two bridges done by Dr. Ambus, the two failed within a year and a half because they weren't sealed properly and kept coming lose, as a result of this, the anchor teeth of the bridges decayed so much I had to have implants to replace them.
My whole family was at the same time being treated by Dr. Ambus and 50- 75% of the work she did on them(my wife and two daughters) has had to be replaced by other dentists as well.
When I explained to Dr. Ambus' office the problems I was having with my bridges, instead of being concerned with my well being they were confrontational and rude.
