Hello Dr Gambroudes, I’m 16, 17 in January and I really want to get my teeth whitened as I feel self conscious about my teeth as they’re slightly yellow. I don’t want to use a home kit as I don’t want to get it wrong. Would someone at my age be allowed laser teeth whitening? Also what are the disadvantages, how long will it take? Will it be noticeable and how will it cost? Thank you for your time and consideration.
