I am the Author of this post, the reason i made this post was to get some idea of cost myself. That said, seems very expensive to me. About 900 pounds a tooth.
So many good tips. I just tried a local dentist here at Bang Khun Thian in Bangkok, they quoted me 8000 for the metal type and 800-1000 for tooth removal. Not too bad, I think.
