Am I shining my teeth right back to stubbly knubs?

Can I scratch or otherwise harm my teeth by occasionally polishing them with bicarb soda?
About once a week I dip my toothbrush into a mouth wash with peroxide in it (1.5% w/v), and then into bicarb soda, and give my teeth a polish with the gritty moosh this makes. I do this because it makes them shiny, gives a wonderful cleaned-by-a-dentist feel, and I've heard it's a good, cheap way to whiten them.
My questions are should I stop? Am I doing them any harm? Am I scratching my teeth, or doing something else I don't know about?
For what it's worth, I haven't noticed any problems, and I keep the stuff well away from my gums, because I know it may be too abrasive for that area.
I've googled around, and have only managed to find glowing endorsements for the practise by folksy sites, or references to bicarb soda being safe because it's not a deadly poison - the rationale being that we use it in cooking), but I haven't found any comment about whether it's safe for teeth.
I asked my dentist, but he only gave me a vague reply that it's probably not the best thing to do because it's untested. When I asked him why it wouldn't be safe when many toothpastes have bicarb soda added, he suggested that it may be a different grade or type of baking soda. Any truth?
