Wise guy! ... Ruined a good healthy tooth on top, by flattening its ridges to make room for his crown below.... without asking me if I want to let him cut away healthy tooth tissue, first. Now that tooth is giving me problems too..! ... What's the point of taking an impression of the mouth if you don't leave the surrounding teeth alone. And this root-canal still hurts! ... Food is constantly being packed under the gum, thru a gap in the crown. ... Also, left a gaping hole in another tooth I had him look at, that was giving discomfort, without telling me the hole in the side was there, and not fixing it, after I constantly complained of discomfort on that side. ... He even pushed his dental pick through the side of that tooth and saw it went into it, and never told me of the hole in the side of that tooth. ... Didn't listen to my complaints of pain, of the food being packed into that gaping hole... But knew how to charge $2,700.00 for his "work" on the root-canal, of the other tooth. ... It seems he wanted to leave the gaping hole in there so it gets worse and needs another root-canal on that tooth too...! ... I was also told the price AFTER he started working on that root-canal, instead of giving me the price before, to let me decide if I wanted to use his services, or not. ... If he just treated ME like this, I'd like to know WHY? ... Otherwise, this could be his normal way of doing things ... under-handed, and deceptive. ... Not recommended. !!! ... No ADA listing.
