I went to Dr. Xa because I needed a cheap dentist.......fast! BIG MISTAKE! Not only is he extremely fast (and NOT in a good way--he rushes through everything and this outcome is far from quality). I think that it is nerve wrecking enough to go to the dentist, but then to have him rush through your appt. and not deliver good work is just ridiculous at $1,300 for a root canal!!!! I am switching dentists immediately!
