I've been using the large-head Radius toothbrush from at least 20 years now. I used to buy them at my Dentist's office (Dr. Nevin Cope in Orefield PA) after each of my bi-yearly check-ups. I don't think they were available in stores back then. I lived in Maxatawny Township very close to the Radius headquarters in Kutztown PA, and remember speaking to a member of the Radius team at an event either at the Rodale Farm or at the Kempton Fairgrounds. I suggested that Radius start making replaceable large heads to reduce plastic waste. The woman from Radius who was at the table said I could buy the small-head replacement brushes, which I did, but I just wasn't happy with the size. I really like the large head brush. Anyways, many years later, I was in a Sprouts grocery store in Palm Harbor, FL, looking for a new Radius toothbrush, and came across the large head model with the replacement brushes. I bought it then ordered a 2-pack of replacement heads off the Radius website. All I can say is, it's about time that Radius came out with the replaceable large head brushes!

I LOVE Radius toothbrushes!! I bought both the replaceable heads and the flex. I also bought a Source brush and LOVE those too!! If there’s one improvement o could suggest it would be to have the Flex big brush handle with replaceable heads! . The handle gets too slippery on the plastic big brush. Or if the Source toothbrush would take big heads. Like if all styles were interchangeable with different replaceable heads that would be amazing!

I’ve been using radius now for almost 6 years. What a difference of brush makes my dentist loves how fast they get me in and out of the area with cleanings. This brush works so well.

MOST AWESOME TOOTHBRUSH EVER!!!
I was visiting a friend in NY, and all her family had these gigantuous toothbrushes. I was spitting with her and making fun of how large they were, and she said , “Don’t knock it till you try it. I thought the same thing.”. So she bought one for me, while I was there (that was in 2009). I WAS SOLD!!! (even though it felt unusual at first due to the size) I’ve been using them EVER SINCE! It feels absolutely abnormal to put a standard size toothbrush in my mouth! My mouth feels as if I am able to do such a better job of getting everywhere! I allllways brush my tongue and rod off my mouth also, and this just has MUCH better coverage for that as well. Thank you for such a unsuspecting (I’d never seen them before her house) but great product, Mucho mucho KUDOS!!! The only negative is when I buy replacement heads, the replacement heads are soooooo much smaller than the ones that come when you purchase the entire brush. I purchase them (brush and heads at our local health food store. That has been very frustrating, because I have felt forced to purchase a new brush each time. But as far as brushing teeth, there’s not a better toothbrush in my opinion! 100 stars! ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
Description

Upgrade your brushing routine and dramatically cut waste with RADIUS Big Brush replacement heads. Featuring a supersized, gum-massaging head and an impressive 6,000 plant-based bristles, these refills deliver a  MOUTHBRUSH experience that gently polishes, protects, and pampers your entire mouth.

 

These are replacement heads only. A Big Brush or compatible RADIUS handle is required.

Benefits

These replacement heads are what give the Big Brush its supersized cleaning power.. With 6000 ultra-soft, plant-based bristles (compared to just 1800 in most standard brushes), the oversized head gently massages gums and helps to prevent recession. The large head evenly distributes pressure over a larger area, helping to reduce bleeding gums and protecting enamel from overbrushing.

The Big Brush head sits naturally at a 45º angle, allowing effortless plaque removal along the gumline.

Additional performance benefits:

  • 300% more bristles for a fuller clean
  • Larger surface area = faster, more effective brushing
  • Helps reduce enamel erosion
  • Bristles last up to 3× longer than conventional toothbrushes
  • All RADIUS replaceable heads fit all RADIUS replaceable handles
Materials
  • Plant-Based Nylon Bristles
  • Head base made from Nylon + EcoPure® (supports biodegradation in landfill conditions)
  • Packaging made from Recycled PET (soda bottles) + recycled cardboard
  • BPA-free
  • PFAS-free
Sustainability

Reduce your brushing footprint by replacing only the brush head - not the entire toothbrush. These Big Brush replacement heads reduce plastic waste by 93%, helping you avoid tossing full brushes into landfills.

Sustainability features include:

  • EcoPure® additive supports biodegradation
  • Recycled + recyclable packaging
  • Long-lasting bristles mean fewer replacements
  • An interchangeable system extends the handle’s life
  • ADA Accepted performance with eco-forward design

A smarter system for your oral health - and the planet’s.
