Query: If your gums are sensitive...............stay away from this one!

I bought the "soft" bristle toothbrush and I can't tell you what torture it was for my gums. The head of the brush is very wide therefor making it more of a brush to your gums than to your teeth. The outter bristles stick our further than the bristles on the inside that would get to your teeth, therefore making the brush useless to your teeth. Feels like you haven't brushed yet. That's my opinion, for what it's worth, and I hope it helps you.
