DO NOT PURCHASE I REPEAT DO NOT PURCHASEIt has damaged my gums and had been having pain in them for a week, they use bleach in it which is in every of there products, sure bleach is for cleaning the bathroom not your teeth. Also doesn’t even whiten your teeth it’s just a scam those ads are fake. Dentists are aware of this rubbish product with it bending gums and infecting them from how much ppl coming in with painful gums. Instant my dentist knew what it was from looking at my gums
