## In short

Radius is a premium kids' toothbrush made by the American company Radius. A parent of two switched to Radius toothbrushes when the children's brushes were due for replacement and found that the rubber grip and small head suited a child who wants to brush alone, while the 30-month-old with sensitive gums accepted the Radius brush without resistance. Because the bristles don't splay easily, the Radius toothbrush offers decent value, and the family plans to buy it again.

## Why I chose a Radius kids' toothbrush

It was time to replace my kids' toothbrushes, and I went looking for a new one and landed on Radius. Brushes differ in bristle softness and feel, so I tend to swap around until I find one that suits my child. Radius looked good in both its design and features, so I picked it.

![Premium Radius kids' toothbrush product](https://img.superchart.com/images/radius-kids-toothbrush-sensitive-gums/radius-kids-toothbrush-sensitive-gums-02-9ptta-1200.webp)

This is the premium Radius toothbrush. It's made in the USA by Radius.

## How are the size and grip of the Radius toothbrush?

The head and overall size are just right for a child old enough to brush on their own, and the part you hold is rubber, so it isn't slippery and feels stable in the hand. The fact that it's made by the US head office gave me personal confidence too. In actual use the bristles don't splay out easily and hold up for a long time, so the value turned out to be not bad.

The head is small to fit a child's mouth, so it's comfortable once inside. The bristle tips are rounded, so it doesn't hurt little gums, which makes it safe. The structure is also nice for small, soft hands to hold. Thanks to the grip that fits snugly in the hand, I felt it suits a child who wants to try brushing alone.

## My child wanted to brush alone

The Radius brushes come in lots of colors, and my child loved them when I first showed them. The brush can also stand upright after brushing, and for the first time I heard my child say, "I'll finish up by myself!"

![Individually packed Radius kids' toothbrush](https://img.superchart.com/images/radius-kids-toothbrush-sensitive-gums/radius-kids-toothbrush-sensitive-gums-08-1wkrf-900.webp)

Each brush is individually packed, so I was very happy with the hygiene. You can even take it traveling without a separate hygiene cap!

An ergonomic handle, a wide head, soft bristles. The dual-blend soft bristles, made from sustainable materials, clean both the tooth surfaces and the gums with no spot missed, so I was very satisfied with how it feels to use.

## How do Radius kids' toothbrushes differ by age?

### Pure Baby (6–18 months)

Radius Pure Baby has about 6,000 bristles and is said to be the softest of the line. It's color-free and non-toxic, with no harmful substances or artificial colors, and can be sterilized in a bottle sterilizer or in boiling water. The soft, plentiful bristles massage the gums, and the 360-degree rounded head means no worry about scratches!

### Big Kids Forever (6 years and up)

Radius Big Kids Forever is a replaceable-head toothbrush with dual-blend fine bristles. You only swap the bristle head, which reportedly cuts waste by 86%. With 2 handle colors and 6 head colors you can mix and match 12 combinations, and just by flipping the handle direction it's comfortable for both left- and right-handed kids. The concave head wraps around the teeth for effective cleaning, and it's said to be a popular gift for kids.

## Was it okay for a 30-month-old with sensitive gums?

The Radius brush barely irritates the gums, and my second child, 30 months old with especially sensitive gums, accepted it without any fuss. With the old brush, the gums sometimes turned red with just a little pressure, but with the Radius that worry has shrunk.

![Radius kids' toothbrush design with pretty colors](https://img.superchart.com/images/radius-kids-toothbrush-sensitive-gums/radius-kids-toothbrush-sensitive-gums-20-1en4p-800.webp)

The design is clean and the colors are pretty, so the kids like it without resistance, which turned out to be a quietly important point too! In actual use the bristles don't splay out and keep their shape, so I feel the value is not bad in the end.

## Is the Radius toothbrush worth buying again?

Thinking about my kids' gum health and brushing habits, I think the Radius toothbrush is well worth the investment. Both of my children are using it happily, and our family plans to keep rebuying it. I recommend the premium Radius toothbrush.
