Dr. Morales is about three (3) times the price of other Mexican Dentists, $400 for a crown vs. $125. $90 for a composite filling, vs $30. Basic difference between is the use of an air suction device to remove contaminated air from the room. Certainly a good idea. IF you can afford Dr. Morales you probably can afford an American dentist too at $725 per crown. And if you are Texas , Nuevo Progresso is a lot closer than Tijuana.
