Hi, have just completed 2 weeks teeth whitening with my dentist using Polanight with overnight trays and 2 sessions in the dentist. However, some of my teeth are not uniformally white – that is some parts of the tooth are whiter than others. I understand that the part of the tooth nearest the gum line may not whiten as much, but some of my teeth have whiter sections than others. When I raised this with my dentist he said its due to the make-up of the tooth and nothing to worry about and nothing else can be done? Would you agree. Thank you for any advice you can give.

Regards
