I think my parents used tooth powder when I was very small....and my grandmother used it....
Then when I got teeth, we became an Ipana family....thanks to Bucky Beaver.
Then we switched to Crest.
When I was in my late teens, I switched to Pearl Drops and within six months had my first two cavities. I switched back to Crest. I now use Colgate Whitening Toothpaste in a small bottle.....on my real teeth.
