What customers say
Customers appreciate the Radius toothbrush heads for their softness, durability, and eco-friendliness. Many users highlight the gentle bristles that effectively clean teeth without irritating gums, making them suitable for those with sensitive mouths. The larger brush head covers more area, providing a thorough clean in less time. Long-term users praise the product's quality and longevity, noting significant savings and reduced waste by only replacing the heads instead of entire toothbrushes. Some customers find the soft bristles too gentle and prefer switching to medium ones for better durability. Overall, the product is well-received for its comfort, effectiveness, and environmental benefits.

Very Good
Verified purchase
I've purchased these for many years, works great and saves you having to buy a whole new toothbrush. I also like that the bristles aren't coloured.

Great
Verified purchase
I love the fact that you can purchase just the head for this toothbrush. Usually a toothbrush handle is still good when the brush is worn out. It seems like such a waste. But with this, I can just change the head and have a new toothbrush for a few months. It is fairly soft, not harsh on the teeth or gums. I will continue to use these as long as they are available. I hope they don't discontinue them.

Convenient

Being new to the Radius toothbrush, I’m glad I ordered the replacement heads. I really like using this fuller head toothbrush. It covers more circumference than conventional shaped toothbrushes. And because it costs more than other toothbrushes, it makes sense to order the one with replaceable heads.

this system is a total game-changer
Verified purchase
I am absolutely obsessed with these replacement heads; they make keeping my smile fresh so easy and affordable! The soft bristles are high-quality and provide a professional-level clean without irritating my gums at all. I love the sustainable design because it saves money and reduces waste by allowing me to keep my favorite handle. Getting two in a pack is a fantastic value, and the 'Made in USA' package quality really shows in how long they last. Honestly, I’ll never go back to regular toothbrushes—this system is a total game-changer

Great!
Verified purchase
Great soft bristles for sensitive teeth that clean well. I haven't had any cavities since using this product. It's gentle on my teeth, but also cleans really well. It's well packaged and has multiple benefits for my dental hygiene. It was recommended to me by a friend, and I recommend it as well if you have sensitive teeth, but want them well cleaned. Also, the size, composition, and quality are perfect for improving dental health care, regardless of age. Thank you for carrying this product on iherb. It's greatly appreciated.

Favorite tooth brush!
Verified purchase
Love Radius products! I love the feel of the brush, and it’s reach. It fits so well in my hand, and with the removable top, it works well for left and right handed users. The quality is excellent. They have various sizes for various ages. It leaves my teach feeling clean and doesn’t irritate my sensitive gums.

Best tooth brushes
Verified purchase
Since I tried Radius, I can not use other regular tooth brushes. And I was really happy when iherb placed them again on their website. Radius gives you a sense of cleanliness in your mouth. Thanks to it's head size, it not only brushes your teeth, but also massages your gums. And this is completely different sensation. Highly recommend!

Great eco-choice!
Verified purchase
Bamboo might be more ecofriendly, but in my humid climate the bamboo handles can get moldy. This is the next best thing! The brushes feel good and I'm glad I don't have to throw away hard plastic handles every few months.
