Never had a cavity for 35 years. Went to trobough and every single visit was a new cavity. The final straw was in December I of course "had a cavity" and trobough was in a rush to get it filled before year end and when insurance resets. Got a second opinion and of course there was no cavity. Had about 8 teeth filled in 1 year while I had no cavities in previous 8 years. A true scam artist you have to be careful with.
