Snap, going in 7 weeks so would be good to get some advice on this as been looking to do the same. The website looks not bad and reasonable priced.Edited: 10 February 2017, 08:55
Haven't tried that yet but if you are still looking for recommendations, Thantakit International Dental Center in Bangkok is worth a visit. Their Zoom2 whitening system is amazing and very effective. Got it at a discounted rate which is awesome. Their dentists are gentle and accommodating too. Fluency in English is also a huge plus.
