I have now bought and tried every adult toothbrush and can say I LOVE them ALL!! The source brush is great with a sturdy handle and the soft flossing head works really well to get in between the teeth. It’s a little too soft for my liking but easy fix to use a different replacement brush!! I appreciate the fact that all the brush heads are interchangeable. My fave combo so far is the source toothbrush handle with the big brush replacement brush!

Extra Soft Bristles Give You A Thorough Brushing

The extra soft bristles help people with sensitive gums minimize that sensitivity, while still receiving a thorough removal of plaque. The thinner bristles actually make cleaning between the teeth easier.

Love the extra soft bristles and their flossing design. I always get praised at my dental cleanings. These replacement heads can be hard to find at my local stores, so I bought six 2-packs to last a long time.

The best toothbrushes ever. I was honestly a little surprised reading all of the bad reviews because I’ve been using this for over 5 years and have the same 2 handles, one for home, and one for travel. They have both lasted me that long. So I don’t understand how other people say that their handles break or don’t last, maybe they’re just being too rough with it? I don’t know. The other thing is, I don’t have trouble with my bristles “falling off”.

Great customer service . . . and products!
This is my second complete brush as the first one wouldn't come apart to change the brush head. I contacted Radius & shared my dilemma & they sent me a brand new complete brush as well as a travel case, at no charge. I am truly grateful for & impressed with their products and their customer service. I'm happy to have found this company as I am trying to reduce my use of plastic.

super soft replacement head
Have been using Radius for many years but this was first purchase of super soft bristles. The uneven cut of the bristles works great for loading it with tooth powder since I switched from paste. Really comfortable clean for teeth and gums.

By far my favorite toothbrush and I’m never using a different one! Even my 1 and 3 year old love using them and the fact there’s no guilt with them being eco friendly is an even bigger win!
