Just posting because I saw a negative IQ teeth whitening guide that was telling people to use 40% h202 gel. Do not do that unless you don't care if ur teeth get sensitive as fuck and possibly crack/destroy ur teeth. The highest % Carbamide Peroxide gel you can purchase in the US has 14% hydrogen peroxide... To avoid sensitivity entirely I'd use 10% Carbamide Peroxide gel in a custom whitening tray for max 4 hours daily and dry your teethbefore you put it on
