since we've had some dental threads lately just wondering what everyone uses..i have been using Colgate Total with Whitening. i switched to Mentadent Replenishing White with Liquid Calcium... after 2 days it seems to have made a noticeable improvement.. i recently bleached my teeth and read that the bleaching process can make the enamel porous, so i decided to try this toothpaste to fill in any crevices the bleaching made.. its not the greatest tasting stuff..
