No it doesn't. Your teeth are a lot harder than the bristles on a toothbrush. There's no way for the brush to do any damage to them at all. Even the plastic of the brush isn't hard enough to hurt your teeth. You're just spreading misinformation.
Edit: I thought I knew how this worked, but turns out I was very wrong. I was thinking in terms of like a scratch test. Turns out I'm the one misinformed.
I went to the dentist for what I thought was a cavity. It wasn't a cavity, it was the nerve becoming exposed by brushing too hard and causing receding gums.
