I have used basic Colgate since I was a kid and I am 72. I love the taste. Nothing fancy and it has the same fluoride as all the others. Crest leaves my mouth feeling funny and white stuff appears at night. My dentist told me that a lot of his patients are allergic to the ingredients in Crest and have the same reaction at night. I am one of them. This is all we use and at our ages (72), we still have our natural teeth and no funky white stuff.
