These are NOT for sensitive gums/teeth
I bought these based on the word "sensitive" in the product description and title. To me, that means that the brush bristles would be extra soft. These brushes are actually stiff, like scrubbing your teeth with a scrub brush. My gums hurt and bled each time I used these heads. I ended up throwing them away as I didn't use the first one until the return window was closed for this purchase.
