FYI up front: due to my dental issues (TMJ problems, bruxism, clenching, nighttime tongue thrusting), I have tried probably thirty different toothbrushes in the last three years. Soft bristled toothbrushes typically leave my teeth and mouth feeling not so clean, so I had been using medium bristles for a long time, but they became uncomfortable on my now-perimenopausal gums. I found this product through a YouTuber (teeth remineralization and oral care topic), and immediately ordered a pack. I like these brushes so much, I ordered several more packs shortly after. The bristles are gentle and soothing on my gums but they leave my teeth feeling clean and smooth. I no longer floss daily (it isn't good for everyone; look up recent, credible research), so flossing bristles that actually work without making my gums bleed is really nice. I have since sent these brushes out to friends in their holiday goodie boxes, and they like them, too. As an aside, I have been working diligently to restore my slightly receding gums (through diet and specific practices), and these brushes may or may not be aiding in that endeavor, but they are definitely not impeding it.
