I used: DENT.CARE CLINIC. (dentcarepatong@yahoo.com)
Sainamyen Road (Near Kathu Hospital)
Tel:076-296-495.(Dr.Sawika Jantarasatit)
Did pay ca 7000 Bath for cleaning and whitening programe.
Alot of frends of mine is also go here and fix there teeth when they are in Phuket.
I was very satisfied and the service was very good.
