We used to use ultrabrite...oof that took the enamel off as well as the plaque.

Anyone have to use these?...

I'm Colgate too. Yes Kizzy, I do remember those, horrible things! For sure they made you overbrush your teeth, my daughter's dentist recently told her to brush only once a day, overbrushing is really damaging.

When I was a kid, we had Signal, anyone remember that?
