Would like a harder brush head. The bristles on the full size brush head are very soft
I would recommend this to a friend!

Thank you for submitting your review. The ADA recommends the use of soft bristles. However, we appreciate your feedback and will pass it on to our Product Design Team.
The smaller brushes are great for getting into those small places in your mouth that are hard to reach with a larger brush. And given the fact that you can brush and floss at the same time, it does double duty!
