Xylitol is the main ingredient in Now's Xyliwhite gel, not a token mention near the end of the list, and that is the reason it earns our top spot. The 6.4-ounce tube is also the largest single tube in this group, which matters if you brush twice a day and don't want to rebuy constantly. We like that the formula stays simple: fluoride-free, SLS-free, and built around xylitol rather than a long list of extras.
The gel texture is thinner than a conventional paste, and it spreads quickly across the brush. It doesn't produce a thick foam, which took us a brush or two to get used to, but the payoff is a clean-feeling mouth without a detergent aftertaste. The mint is mild and clean rather than sharp, so it's a good match for someone who finds strong peppermint overwhelming.
What it doesn't have is hydroxyapatite or another dedicated enamel-repair ingredient, so we see it as a straightforward daily cleaner rather than a remineralizing treatment. For most adults who want xylitol first, that simplicity is the appeal; if you're specifically shopping for nHA, Boka or Ollie is the better fit. The value is hard to argue with for the size.
Pros
- Xylitol is the main ingredient
- Large 6.4-ounce gel tube
- Fluoride-free and SLS-free
- Mild mint, low-detergent feel
Cons
- Thin gel can slide off a dry brush
We recommend Now Xyliwhite as the default xylitol toothpaste because xylitol leads the formula, the large gel tube lasts, and it cleans without fluoride or SLS.
