RADIUS Flex Brush

Important note on kid-friendly toothbrushes

When I’m choosing a toothbrush, I focus mainly on the bristle material. Bristles are used multiple times a day and sit in a warm, wet environment, so I prefer brands to state what they’re made of clearly. Most toothbrushes use nylon bristles, and that’s still the most common and reliable option. I prefer new (virgin) nylon for bristles over recycled nylon because it offers greater consistency in structure and performance and reduces variability that can arise from recycled materials. I also skip toothbrushes that use antimicrobial or antibacterial treatments on the bristles and look for simple, untreated nylon instead.

What I avoid in toothbrushes

I avoid toothbrushes with antimicrobial or antibacterial treatments on the bristles, unclear or undisclosed bristle materials, recycled-plastic bristles, and unnecessary coatings or additives. I prefer straightforward designs that prioritize comfort and effective brushing over gimmicks.

Product description

The RADIUS Flex Brush is a manual toothbrush designed with soft nylon bristles that flex with brushing motions. The handle is ergonomically shaped to feel comfortable in hand and provides a grip that works well for a range of ages. The flexible bristle design is designed to help the brush adapt to tooth contours for a thorough cleaning experience without causing excessive abrasion.

This brush’s design makes it easy to use for daily brushing and is a practical option if you want a toothbrush that’s a little more adaptive while still using familiar and predictable materials.

What I like

I like that the materials are clearly disclosed, the flexible bristle design helps the brush adapt to teeth and gums, and the soft nylon bristles are comfortable for daily use.

Things to keep in mind

Like most toothbrushes, this one still uses plastic-based materials, so regular replacement is important, especially once bristles begin to splay or flatten.
