I went to this doctor for implants. He did all the exams and said he would need to do 4 implants which he did. Within 3 months they began falling completely out of my mouth. I called him and he said he would pay me 1500.00 for each implant that fell out. Well, the first two years 3 implants fell out and the 4th one fell out in 5 years. He paid me the nominal amount back on the 3 implants, considering all the pain and the failure of his work, but when it came to the 4th one he refused. A lot of this could have been resolved with one xray to show I didn't have enough bone to hold them in. Beware he's only nice to you until the statue of limitations are up, then too bad for you. So, apparently his word is only good during the time I could have sued him. Dr Vergara is not trustworthy! So I'd say he was very expensive to me for his mistake both in the pocketbook and pain-wise.
