are dentists cheaper up north , say in chiang mai for example, as compared to bangkok,,,,how about phuket?.....or does the location not make a difference? thank you

From my experience i think Phuket 's dentists (esp. ones at tourist attraction sites) are more expensive than those in BKK or Chiang Mai . Prices actually depend on quality and grade of clinics. Most farangs friendly clinics are relatively more expensive then average.
