Clinically Proven to Remove More Plaque

A rigorous clinical study tested Willo against a top-rated manual toothbrush approved by the American Dental Association. The results were clear: kids aged 5 to 13 who used Willo had significantly less plaque after just one brushing session.

On average, Willo removed 60% of plaque, compared to only 20–25% with a manual brush. It was especially effective in hard-to-reach spots — like the back of the mouth — removing up to 7 times more plaque than the manual toothbrush.

Why it matters? 

Less plaque means better cleaner teeth, less buildup, and healthier smiles for your kids — every time they brush.

How Do We Deliver These Results

Willo was developed alongside pediatric dentists to mimic the dentist-recommended brushing technique using short back-and-forth strokes to remove plaque from the teeth and along the gumline. Our patented design ensures a consistent, effective clean. And our kid-first design ensures kids want to stick with the routine!
