Re: whitening teeth
You can purchase kits in stores like Wal-Mart, K-Mart, Target, Etc., but they will only whiten about 2 to 3 shades, TOPS. If you are looking to dramatically whiten your teeth, you would need to obtain a kit from your dentist. Also keep in mind that if you have any white fillings or crowns, they will not bleach with ANY system you can buy. Hope this helps!
