third obama term. mike slater is here next my hygienist said the most random thing. she said i should think of my teeth like an apple. it could be great on the outside not so great on the inside. her advice? use a toothpaste and mouthwash that strengthens both. go pro with crest pro-health advanced. it's uniquely formulated with activestrength technology to strengthen teeth inside and is better at strengthening the outside than colgate total. crest toothpaste and mouthwash makes my whole mouth feel amazing. advance to healthier gums and stronger teeth from day one. my check-up was great. crest. healthy, beautiful smiles for life.
