I had the procedure done 2,5 years ago in Patong.I was told that I was gonna get the nasty "icing"-sensation for about a week...the first week after I didn`t feel a thing,but for over a year afterwards I got that "icing"-sensation in my teeth,both with cold-and hot drinks
!!!
Beware that there is 2 types of teeth-colours...the lucky ones have nice white teeth`s that goes bad because of,smoking,red wine etc.,for those laser-whitening is perfect !!
I don`t have those
...so for me I`didnt notice any difference,in fact the plaque-removal procedure I took in the same dental office the year before had a better effect than the laser-whitening !!!
