Pediatric Dentist

My kids are almost 4yo, 2.5yo, and 1.5yo. We've been going to the only pediatric dentist here in Lopburi for a few years now. And while they eventually end up getting the examination and any plaque removed, it is always a bit of a production with me having to do most of the entertaining, assuring, etc. The dentist and assistants are not very helpful in distracting or entertaining, but rather try to rush through the process which my kids pick up on and react to.

I was wondering if anyone had any recommendations for a pediatric dentist. It would be great if there was someone in the greater Lopburi area, but I am perfectly willing to make a trip to Bangkok if needed.

I did contact Samitivej (via email), as I have had good experiences with their regular pediatricians. And they quoted me 1,200 - 1,600 baht for a simple exam and cleaning for a child. Is that really the case? Expected pricing would be appreciated. And I will probably call around to see if the price is a bit more reasonable. Am willing to pay that if that's what it really costs for a check-up with a qualified pediatric dentist, but curious what others pay.
