Wide-head kids' toothbrushes by age, 6 months+: Radius Kids Toothbrush

In short

Radius Kids Premium Toothbrushes are a line of age-specific children's toothbrushes from the oral-care brand Radius, covering babies from 6 months up to elementary school kids. The writer compared four models (Pure Baby, Tots Tots Pastel, Tots Plus and Big Kid Forever) and brushed with their child, finding that Radius toothbrushes cleaned more widely and thoroughly than a regular kids' toothbrush. For parents looking for a soft toothbrush matched to their child's age, Radius was a highly satisfying choice.

What kind of brand is Radius?

Radius describes itself as an oral-care brand with 40 years of history and the number one toothbrush in US sales. Its kids' toothbrush is said to be the only children's toothbrush certified by the American Dental Association (ADA) for both excellent cleaning power and gentleness, so I could order with extra confidence, since it's something my child puts in their mouth.

On top of that, it's a brand stocked at Seoul National University Hospital, and it keeps working for the environment with biodegradable toothbrushes.

Radius Pure Baby is just right as a baby's first toothbrush. It's made with about 6,000 super soft bristles, so it's full and gentle and perfect for massaging gums, and it's said to be dye-free and non-toxic, made without harmful substances or artificial colors.

The 360-degree rounded head means no worries about hurting your baby's gums~ It can also go in a bottle sterilizer or be boiled, so it's easy to keep clean.

Radius Big Kid Forever is the only replaceable toothbrush in the lineup, where you swap in a refill for the bristle head. You can mix and match 2 handles and 6 heads and change up the colors.

It's a dual-blend fine-bristle brush designed so kids whose permanent teeth are coming in, and who may have lost some teeth, can brush every corner. Flip the handle direction and it works comfortably for both lefties and righties, and the concave head wraps around the teeth for a clean brush.

Does a Radius toothbrush clean better than a regular kids' toothbrush?

Brushing with the Radius wide head and dense bristles, it definitely felt like it cleaned a wider area of the teeth more thoroughly than a regular kids' toothbrush. The teeth got relatively clean, so I was very satisfied.

I especially liked the feeling of it gently massaging the gum line between the teeth.
