I'm an adult male. My dentist has not informed me of any particular concerns. I wouldn't mind my teeth being a bit whiter. Which of these am I supposed to buy? Or am I supposed to buy a product from one of the other brands of the same manufacturer... Elmex, Meridol, several others, each of which has their own outrageously long lineups. Or look at a different manufacturer?
