teeth whitening experiments

I use baking powder and water to whiten my teeth, but how many times should I put it on?
So everyday (twice a day: morning and night) i use baking soda and water to brush my teeth. will it do anything bad if i use it too much?? should i just use it once a week or somethin so it doesnt go too far??
p.s.: im using it for a month to experiment ;-D
i was thinking the same! but nothing saying anything about baking or water for a tip of whiten teeth online so I guess it not going help. Nut i found out online that say uou can use at home remedy for teeth whiten is strawberry seeds . slices them and mash to make them toothpaste include seeds then brush on teeth but you can add baking if want. But warning, you must do it once a week because it can hurt gum or be sensitivy to the parts of teeth. you know how teeth whiten product can only whiten but not forcus on gum, cavity , or etc, they harm them? it is same with strawberry seeds! it is why you must do it once a week! be sure it is plenty small and then do it next week once (optional) or you can add strawberry with seeds in blender shaker with grape and drink as you make sure they are passing upon teeth , teeth will get white by strawberry and grape too. they have like antibacterial and something that make teeth white because they are good for body that why they are calcuim . if they make teeth strong then they make teeth strong. But stay away from veg. they make teeth yellow since they are green. I was shocked when reading online but yea true. You still can eat sometimes but not as often as fruit. Fruits are the best one and milk always make teeth white as long you pick it from store because in farm coming from cow freshly, they yellow.
