    • dentistry of the last century.
      nice work, but outdated materials.
      today no one wants to look like jaws from moonraker.

  1. Excellent techniques, a truly skilled outfit.

    Adapting to modern ceramics and the new generation of orthodontic prostheses will be a piece of cake for these “dental artists”.

    That done, the money should start rolling in, in large, leafy bales, if the price is right.

    “Dental tourism”, anyone?
