What is the best Teeth whitening product in stores?

i went to the dentist to get my teeth whitened but it is to expensive, somebody told me that the product at the stores do the same things and its a lot cheaper, does anybody know which products are good for this? thanks

There's a few different things you could do. You could try brushing your teeth with baking soda, if you do that once or twice a week you should see a improvement. The only problem with that is whether you would remember to actually do it, because i didn't. The best ways to whiten your teeth would be to use bleaching trays or have you teeth laser whitened. If getting them professionally done is too expensive then you can get whitening trays and bleach in stores or off ebay. I know it sounds a bit dodgy but the ebay ones are actually really good. Just make sure you do not buy any bleach over 25% otherwise it will wreck your teeth and make them very sensitive. I hope that helps
