Doesn't work for me
I had the complete Opalescence Go set with whitening bits for 10 days, but it barely made a visible difference for me for a relatively large amount of money. Definitely not worthwhile for me, even considering the time and energy I've put into it. The dental hygienist did indicate that the result may vary from person to person (has to do with lifestyle, etc.).
