Crest Whitening Strips (including Premium) did nothing for me, 4 boxes later. Are the other kits better? Or maybe those kits are for people with white teeth already who just want a lil pearly boost? Is there anything else I can try at home to make my teeth less yellow? I dont drink coffee or smoke or drink too many sodas. Im paying the price for not caring for them when I was a kid. They have been yellow for the past 13 years. I cant afford professional bleaching just yet. So any remedies, even unsafe remedies, please share!
Also, do the dental school's do whitening at a discount or is that just cavities and such?
