Which Asian is best for seeing a dentist?

I've lived in mainland China for several years and both studied and worked here, but haven't visited any dentist during this time. I'm moving between different Asian countries, primarily in south-east Asia, and am planning to see a dentist quite soon as I need a thorough examination and probably also some holes to fill.

Was wondering which of the following countries would be the best option for me, considering total costs and value for my money and language/communication with the dentist?:

Hong Kong, mainland China, Taiwan, Singapore, Malaysia, the Philippines, Thailand, India.
