save 250 dollars when you test drive and buy a john deere residential z540r ztrak mower. i try to take care of my teeth, but there's acid hiding in what i eat and drink everyday. i can't imagine how much damage that's doing over a lifetime. so my dentist told me to go-pro with crest pro-health. go pro with crest pro-health. the only toothpaste with the ada seal of acceptance for protection against acid erosion. i like knowing that my teeth are protected. crest pro-health protects against acids in everyday food
