Can i whiten my teeth by brushing them a lot?

Ok i guess what im asking is will my teeth be whiter if i brush correctly with an electric toothbrush for like an hour straight, reapplying toothpaste every couple minutes. is that a bad idea? like could it damage my teeth or something and no i dont have sensitive teeth, cavities or crowns or anything like that

That probably wouldnt be the best idea. But if you want an inexpensive way to whiten your teeth, you can use baking soda to brush your teeth, for about 5 minutes. It doesnt taste very good but it works. Just dont di it too often as it can wear your enamel off. Or you can use hydrogen peroxide (the 3% one from drug stores) and swish it in your mouth. Again, it tastes weird but it works! And this one you can use daily, which I do as a mouthwash. The hydrogen peroxide may burn your gums a little bit if they are sensitive, like for me, but I just dilute it a bit with water and its fine. And, you can mix baking soda with hydrogen peroxide and use that paste to brush. When I did this I saw results pretty quickly.
