Hiya\n\nI recently bought for the first time a colgate toothpaste with fluoride and have been using it for a week or so,i've noticed my teeth have been getting stained and really sensitive,i have always used colgate toothpaste but its a first with fluoride,and this has never happened before and after doing some research i read that fluoride can stain your teeth but also prevent cavities(?).\n\nI always had colouration at the tip of my two front teeth but it was never so noticable before i started using this paste. I am going to switch back to a different toothpaste but will it revert back to how they were? They were quiet nice teeth before,shiny,not blinding white or yellow (just how theyre supposed to be), im really scared that my teeth wont go back to how they were because of the damage fluoride may/can cause to the teeth,hopefully they will be fine since i havent used it for too long.\n\nWhat are your toughts on this? Will they go back to how they were or not?\n\nThank you,any help i will be internally grateful for.
