Dental Health Essentails Yellow teeth Lenoxa Kansas

Bought the 35% gel to whiten teeth. When arrived 1 cap was off the tube tried to call for 2 weeks straight kept getting a recording then a   week and 1/2 goes by and i try again still no answer. I thought i would try a tube and try to get ahold of them later. Well ive bleeched my teeth for several yrs now and used all the different percents. This did nothing after 30min everday for a week no difference at all. Kept calling to tell them still no answer. My husband tried to bleah his teeth to and said the gel doent work . After calling everday all day i finally got ahold of someone he said it was too late to return it i told him iam not payig for a mint flavor gel that doesnt whiten teet. he said WE DO NOT GURANTEE YOYR TEETH WILL WHITEN wth then a company who sells bleach and they dont gurantee it. So i asked to speak to the owner its been 2 days now and he will not retun my calls. If this doents whiten MY TEETH WHAT SUBSTANCE IS REALLY IN THE TUBES. Even a lower % will whiten a little in 30 mins not happy they will not give me an refund and call me back. IN MY OPION I THINK THE GEL IS A FAKE. pPlease do not buy from them
