What age is it safe to use teeth whitening strips?

also if they are not old enough to use them is it bad for them to use baking soda instead, or will it ruin some enamel? thank you!
--------------------
I use them a lot and I'm 14. I used them when I was 13 as well. I would get the whitening trays instead, though. My whole family agrees that the strips are useless. I've never heard that baking soda will whiten your teeth, but I would go for a whitening toothpaste. I know those work really well. If I were you, I'd switch your other toothpaste to a whitening toothpaste and use the trays. You can usually just whiten for a three or four days and see results, then just use one tray when you notice your teeth looking dingy. Best of luck!
