Warsaw Dentists or Phuket Dentists?

I need to have some dental work done (crown, extraction, root canal and 2 veneers) and I am trying to find an affordable option in either Warsaw (Poland) or in the nearby areas, or in Phuket (Thailand). Travel is not a problem for me. I would like to read some recommendations from people who have been in either of these 2 countries and have had great dental work done. Obviously quality work is essential. Thank you in advance.
