Whilst there is no shortage of information on the dentist industry in Thailand, it is not always easy to tell how good that advice is. One major issue is that the information is rarely independent and unbiased. When looking for a truly independent opinion on the internet it is worth asking who is providing the information and what is there incentive.
Having spent many hours researching Bangkok dentists on the internet it appears the majority of information and recommendations come from the following sources;
Dentists and dental practices
Tourism or directory services providers
Blogs and posts to secondry sites (Trip Advisor, Reddit, etc)
