“Basic toothpaste. Made not one jot of difference to my tooth colour. I think these products work or help but not on aged teeth like mine. I’m 72 and have tea/coffee stains and yellowing due to my age. I’m very dental conscious because I want to keep my teeth until I die so vidit the dentist every 6 months for check up and scale. I can’t afford veneers etc. at this stage so was greatly hoping your products would work for me but not to be. Equally the whitening powder I use with the toothpaste hasn’t made any difference at all. I’ve been using paste and powder for over a month now. Unfortunately there is no sign of any improvement.”
