It’s a scam. I should have read these reviews. Purple dye on your teeth is a gimmick. It just makes your gums darker. Tiktok and Instagram adverts feel trustworthy but they aren’t. The actors in the ads and the 5 stars are all influencers on the payroll, while we waste our money. They will disappear in a few months and rebrand as no customer will buy this product more that once.
