Painless soft toothbrush for kids who hate brushing: Radius Kids

In short

Radius Kids Toothbrush is an age-based line of baby and children's toothbrushes from the American oral care brand Radius. A child who disliked a previous toothbrush because it hurt switched to the Radius Kids Toothbrush and found that the soft bristles barely irritated the gums while still cleaning thoroughly into every corner. The child said it "doesn't hurt" and started wanting to brush alone, making the Radius Kids Toothbrush a pick that combines softness with real cleaning power.

I was wondering which product would be good for my child's brushing, and the one I ended up choosing was the Radius toothbrush. The toothbrush we used before often hurt, and my child hated it, so I went looking for something softer and safer and found this. Satisfaction after actually using it was quite high, so I'm leaving a review.

What kind of toothbrush brand is Radius?

Radius is an oral care specialist brand that has reportedly been the number one seller in the US, with a tradition going back more than 40 years. What impressed me most was that the American Dental Association (ADA) recognizes its products for both cleaning power and gentleness.

I also heard it is stocked at Seoul National University Hospital, which made me trust it even more, and the fact that it's an eco-friendly brand using biodegradable materials also influenced my choice of the Radius toothbrush.

Is the Radius kids toothbrush really gentle on a child's gums?

The first thing I noticed about the Radius kids toothbrush line I used this time was that it is definitely soft. The bristle tips are rounded, so even when they touch the gums there is almost no irritation, and my child could use it without resistance.

Thanks to the dual-blend bristles in particular, it felt like it was caring for the tooth surface and the area between teeth and gums at the same time, and it felt like it cleaned thoroughly right into the corners.

I felt this is definitely what sets it apart from ordinary toddler toothbrushes.

Is the handle easy for a child to hold and brush alone?

The Radius kids toothbrush also puts a lot of thought into the handle. It's built to be easy to grip in a child's hand, and the wide head let me brush efficiently.

It's also designed not to slip, so it was good for my child to practice brushing alone. Because of that, I thought it would work well as a toothbrush for daycare too.

Which Radius toothbrush should you pick for your child's age?

Another plus is that Radius toothbrushes are split by age into Pure Baby, Totz, Totz Plus and Big Kids Forever, so you can choose to match your child's growth.
