As an alternative, Dr. Fabian, Stetic Implant & Dental Centers in Nuevo Progresso, right across the border from McAllen,TX is an outstanding dentist. I had 8 crowns done. He drilled and did temporary fillings on one day and had the final product the following afternoon, and they fit perfect. It has been 3 years and no problem with them and they look great. He charged me $150 per. crown.
He also does implants, but I have no first hand experience to convey. But if I were considering an implant, I would certainly check with him first.
