Can anyone refer me to a decent place to do the laser teeth whitening in BKK? Preferably in the Banglamphu area... Thanks!

Not for the Banglampu area...

But I have had veneers and teeth whitening a few years back at Tantrakit dentists in the All Seasons Shopping next to the Conrad hotel.

After and excellent and professional service I'll head there again this month and take a member of visiting family.

Teeth Whitening as common as it is should be at a good standard at any reputable hospital or private dentist practice.

Any idea how much it costs, for an average treatment?

around Banglamphu there are at least 10 dentists-of which at least 5 advertise heavy in english and have a lot of farang-clients. ALL advertise with laser whitening-there are now 2 procedures ( laser and at home)-laser mostly cost about 6/7000 THB/some offer discount for 2 at the same time!

As I have never done that myself, so no rec. I have used 2 dentists over there-both on Chakrapong road and both I found quite good-normal dental work.

some have websites-try google or like khaosandental or so. But these may be out of date
