Twice a day

Style: Bubblegum Fluoride

Took a few brushing sessions for our toddlers to not hate the bubblegum flavor. Understandable though since she's never experienced that flavor before. Teeth look clean after using, just hope that they actually are.

Misleading Advertising and Flavor Discrepancy

I recently tried this toothpaste, and I have to say that my experience left me with mixed feelings. The product claims to be suitable for ages 2+, but the bottle itself states "ages 3+," which is a clear discrepancy that could mislead parents. One of the most disappointing aspects of this toothpaste is its flavor. Despite being marketed as "Marshmallow Sparkle," it does not taste like marshmallows at all. Instead, it has a sweet mint flavor, which may not be well-received by children who were expecting a marshmallow taste. This flavor discrepancy can lead to confusion and disappointment for both parents and kids. On a positive note, the toothpaste is fluoride-based, which is essential for cavity prevention. It is also vegan and dye-free, making it a safer option for kids. However, the misleading age recommendation and the flavor mismatch are significant drawbacks that should be addressed by the manufacturer.
