Mouthwatchers is a small business established by Ronald Plotka, DDS, specializing in antimicrobial toothbrushes designed for deeper cleans.
Here's what writer Emma Lord has to say: "I love it just after the first few days of use! I use an electric toothbrush usually, but I feel like I'm getting a much more satisfying clean from these?? Especially because I tend to get yellow stains between my teeth no matter *how* much I floss, and these bristles seem to actually target that a lot more effectively."
Promising review: "I'm amazed at how well this toothbrush cleans my teeth — it definitely gets between the teeth and also more importantly for me, gets in the small, deep crevices in my molars where I always have food stuck and regular toothbrushes couldn't get stuff out. I brush more often (after meals/snacks) because of how effective it is. As stated, definitely go easy around the gums. The bristles feel soft, but will cause your gums to bleed if you use regular pressure. Nice and easy does the trick, SO WELL!" —Jason A.
