Works But.... One caveat
The cancer-causing sweetener Saccharin is in the whitening gel.  Gave me terrible heartburn, lasted all night long.  Suggest not doing this at night, because of that!<br /><br />As far as whitening goes, it's easy to use.  If your teeth are very yellow, it won't make them white, but it will improve them.<br /><br />Can we please put some other more Natural sweetener in this?  Like sucralose or monkfruit or something?
