Bests & Worsts Reviews from Amazon

I havr always used colgate optic white bought at rite aid or walmart. I thought I'd give this one a chance because of the enamel strength! 1st day great! Tingling and squeeky clean! 2nd day gums hurting. 3rd day stopped because my ear started hurting because my teeth were hurting becuase my gums were sore! Being a licensed nurse for 20years now and a specialist of the body! I know everything is connected throughout the body. My gums were affected so my nerves in my teeth were affected as well as my ear! Are you fricken serious! This product should be discontinued! Went back to my regular colgate bought at walmart. Mouth and ear are back normal!!! NO! I DONT RECOMMEND THIS PRODUCT FOR ANYONE!!!
