There must be at least 50 dentists here in Pattaya. I stick to one who is very good with reasonable prices. 700 baht $20 for a clean, from a dentist not just a hygienist. I've had a root canal and crown 16,000 baht $450 and 2 front porcelain crowns 20,000 baht $570. A filling would be around 1,000 baht. Coming from the UK, with the worst dental service in the world, it's amazing to have the choice and low prices.
