From what I gather, it depends on whether your teeth are discoloured from smoking, red wine, tea/coffee drinking etc or if they are naturally carry a more yellowish hue.
I did the laser whitening in the dentist's office about 8 years ago and, for me, it was a huge waste of money and I wish I hadn't let him talk me into it!!
Couldn't notice any colour difference with my teeth at all!! I ended up $800 out of pocket and left with teeth so sensitive I couldn't talk to people if there was a wind blowing because it would hurt so much!!
Maybe the technique has changed since I did it???
EDITED TO ADD: Sorry - didn't read that you were asking if the price was reasonable, not others' experiences. Ignore my post!!
