The breath mint that lasts for hours - I've never seen anything like it - Dentiva is a breath mint that stays minty for hours (reminds me of Willy Wonka's everlasting gobstopper...). Supposedly it also cleans your teeth, which sounds too good to be true, but I certainly hope it is since I'm addicted to these... does anyone know if I can buy Dentiva in the store? My dentist friend gave me some, but I can only seem to find it online...
