When it comes to your toothbrush, always replace instead of creating more waste. These Radius Source Replacement Heads work well with the Radius Source Toothbrush so you can keep your main toothbrush use after use and reduce plastic consumption and waste by 93%. These super convenient brushes feature a long, thin neck so you can easily reach where you need to brush, too. Plus, they’re paraben-free, made in the U.S., vegan, and Leaping Bunny–certified.
Grove can help you with all of your oral care needs. Shop toothbrushes, mouthwashes, vegan floss, and toothpaste, and get all your products shipped out on one date.
How often should you replace a toothbrush head?
The American Dental Association (ADA) recommends changing out your toothbrush head every three months, so you can avoid using a toothbrush with too much built-up bacteria.
