Great for kids
Color: Lightgreen
The HUACOCARE Kids Water Flosser and Electric Toothbrush Combo is an absolute game-changer for establishing a solid dental hygiene routine with children. The light green giraffe and monkey design is incredibly charming and immediately turned what used to be a bedtime struggle into a fun activity that my child actually looks forward to. Having both the sonic toothbrush and the water flosser in one compact unit is brilliant, as it saves counter space while ensuring that every part of their mouth gets a professional-level clean. The three gentle flossing modes and two sonic brushing modes are perfectly calibrated for younger, more sensitive gums, providing a thorough clean without any discomfort.
One of the standout features of this set is how braces-friendly it is; the water flosser reaches those tricky spots around wires and brackets that a standard toothbrush simply can't touch. It is clear that a lot of thought went into the ergonomics and the "fun factor," making it a perfect gift that is both practical and engaging. Since we started using this combo, our dentist has noticed a significant improvement in plaque removal and overall gum health. If you are looking for an all-in-one solution to build healthy brushing habits and make dental care feel like less of a chore, this set is worth every penny.

Sweet Marshmallowy Heavens.
My kid loves this. It's all he uses. He does manage to get it all over the world. I'm not even sure how. It's like... coming out of his hair, rolling down my cabinets, wandering into the kitchen. But that's not the fault of Burst. At least not until they make disappearing toothpaste. Disintegrating toothpaste! OMG I NEED THAT. Can we get toothpaste that disappears after the 8 year old runs wild with it? Please? In lieu of disintegrating toothpaste... this is the bomb. He can't stand the minty stuff and says everything is "TOO SPICY." Welcome to life kid. It's all too spicy out here. Except this toothpaste. It's perfect.

I am never going back to other brands as long as there is marshmallow
This is best marshmallow mint flavor toothpaste. It is my daily morning toothpaste so I can go straight to drink my first cup of coffee or tea. You know what, the coffee or tea still taste like yummy coffee or delicious cha!!
I am so glad I found there products. Hope they always keep marshmallow. I would really like a matching mouthwash of marshmallow mint. Oh the color is lottel pastel. It smells like candy. Its absolutely worth the price.....if you like it

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.
