Our New Big Kidz Toothbrush Will Have Your Kids Begging to Brush Their Teeth

May 13, 2022

Is it a daily struggle getting your children to brush their teeth? It doesn't matter how many times you explain why brushing is so important, they still don't want to give in – even after they snuck off to eat an entire bag of sweets.

Here at RADIUS, our big kids allowed us to experience the same struggles first hand. Yes, we begged, pleaded, and even bribed our kids to brush their teeth. (Okay, we didn't say we were proud of it.) As parents, we wanted the best for our children’s growing bright smiles – and to keep our sanity intact. Our goal was to help our growing kids become more independent in their oral care routines and make them actually excited about it. 

That’s why we constructed the first ever Big Kidz Replaceable Head Forever Brush. Your growing big kid has a lot on their plate– from homework to after school activities– brushing never makes the top of their list. (Who can blame them when you can be Superman all day or hang out with friends instead?) 

At RADIUS, we were determined to design a product which would make brushing not only easier, but funner for our big kids. We wanted to give them a brush they would look forward to using, not roll their eyes at. Especially since more than half of children ages 6-8 have had a cavity on at least one of their baby teeth. 

Our Big Kidz Replaceable Head Forever Brush is  perfect for your growing 6-12 year old. This innovative brush gives your big kid the independence they crave and the clean teeth they deserve– not to mention a fun colorful twist to fit their unique style.


RADIUS is always looking for imaginative ways to improve the health of families everywhere– meaning we like to think outside of the box. It was obvious a standard cartoon straight edge toothbrush wasn’t tackling the twice daily brushing battle or plaque build up for our kids. So we did something about it. 

The new Big Kidz Replaceable Head Forever Brush is the first of its kind for your one-of-a-kind big kid! It makes brushing easy and fun for kids while providing all the health and safety features parents value. It’s also non-toxic and free from BPA, lead and phthalate– giving parents and the Earth a sigh of relief. 

The Big Kidz Replaceable Head Forever Brush is perfect for ages 6-12– when cavities become more prominent. (But little one’s should start brushing at the arrival of their first pearly white– with a little help of course. Check out our Totz brushes here– perfect for your little one beginning on the path to a healthy smile.)

An Easier Way to Brush

RADIUS strives to make brushing as easy as possible for our busy big kids– and their parents. After struggling first hand with our own kids– and a lot of imagination– we feel we’ve covered all the basics. 

The replaceable head and forever usable handle gives our Earth a big high-five by cutting waste by 86%! Instead of rushing off to the store to buy a whole new toothbrush every month, just replace the landfill biodegradable brush head and keep the cool looking handle to use over and over again. 

Our innovative reversible non-slip grip handle is perfect for rightys or leftys who are a hurry to rush off to soccer practice. This allows your child to successfully get those hard to reach places with ease, which cuts out the frustration and tackles those continuously missed spots. 

Our wider bristle bed cleans a larger area in less time. This allows them to make the most of their 10-30 second brushing session before they run off the save the world in their super hero cape! 

The pillow-soft bio-based bristles gently remove plaque and tartar without irritation or gum recession. This make their brushing experience more comfortable and they may even feel like brushing for longer!

The slim neck of the Big Kidz brush allows them to properly clean tight hard to reach spaces they normally can’t reach without a little help– giving them a greater sense of independence and a happier follow up visit at the dentist. 


Your big kid is unique, so why shouldn’t their toothbrush be too? Does your future track star want a blue and green brush to match her sneakers? We’ve got her covered. And maybe your town's next superhero wants to keep his identity a secret, but still represent superheroes everywhere. Our blue and red replaceable head brush combo is exactly what he needs to stay incognito. 

Big kids are always changing their minds– and we mean always. So we wanted to make sure they had plenty of options to choose from and an easy way to switch out colors when they were “so over it” without tossing the whole toothbrush out. Our Big Kidz Replacement Head Forever Brush comes in 6 starting colors, but we offer additional replacement head colors– giving your big kid a wide array of color combos to choose from.

Since we manufacture everything in-house on our own machines in Kutztown, PA, we are always adding new colors to the mix! Offering your kiddo the freedom to mix and match until they find the perfect toothbrush combo for their unique vibe.

How To Get The Best Brush in a Few Easy Steps

*For our younger big kids*

Now that you have the really cool replaceable head toothbrush and an organic toothpaste they'd rather eat than brush with- how can you ensure that they get the best clean?

Try the “Monkey See Monkey Do” approach. Kids love copying their parents. And if you both have the same nifty toothbrushes– they will be even more stoked to follow suit. 

Also, let them explore their new cool toothbrush and sample the toothpaste. Let them practice changing out the head and adding a pea sized amount of toothpaste on the soft bristles– also nurturing that new found independence. 

Make sure they are brushing in a gentle circular motion– not sawing side to side. (This can lead to gum erosion over time.)

Try to brush for 1-3 minutes twice a day.

Can’t get your kiddo to sit still that long? Try blasting your favorite tunes and challenge them to brush for the duration of the song. Kids love a fun challenge and opportunities to see their parents break out their retro dance moves. 


Give your big kid the independence to take the reins on their smiles and brush the way they really want to brush. And let the Big Kidz Replaceable Head Forever Brush do its thing!

Let your child’s smile shine bright with the help of our Big Kidz Toothbrush today! Their dentist and the Earth will thank you later.

RADIUS– good for your health and the world.
