I've used Tom's - never really felt like it was any better than Colgate. Because of the cost I don't use it. Use Colgate, and have for decades. Since I now have upper dentures and only 6 teeth left on the lower, I will stick with Colgate. My dentist told me and hubby (Hubby has all of his teeth) not to use any that is abrasive. Brand doesn't matter - BUT to floss regularly. He also only recommends ACT mouth wash/rinse. I use it diluted 4 to 1 (1 part ACT) to clean my dentures with. Some times I use diluted Dr. Bonner liquid soap to cleanse them with. Diluted 20 to 1 (1 part soap).

The reason I have no teeth is because I had no dental care - no money to pay for it. Never flossed either. Brushed two to three times a day though. Hated mouth washes/rinses, so I never used them. Now I do. I really don't want to lose my remaining teeth.
