Q. Hi Rob, I am considering in-surgery whitening and wondered if you could advise on the best products/procedure available? (highest quality/results possible) How long it lasts? A good cost benchmark etc? My teeth are in good shape so i have ruled out veneers as i think whitening will give me the results i’m after. In particular i have heard of a “bio” laser treatment but have found very little info (I assume then that this is just the normal Zoom style treatment of gel + laser). I am based in Birmingham so would appreciate any recommendations for a surgery to go to! Many thanks in anticipation of your help! Regards
