Crest 3D White Whitestrips 2-hour Express

I bought this and used them one night for the 2 hours it recommends. I took them off after the time was up and found no visible difference in the whiteness of my teeth. About 4 hours later I was in excruciating pain. My gums, teeth and jaw all hurt...   +

I bought this and used them one night for the 2 hours it recommends. I took them off after the time was up and found no visible difference in the whiteness of my teeth. About 4 hours later I was in excruciating pain. My gums, teeth and jaw all hurt so bad I was in tears and nothing helped to relieve my pain! The pain lasted all night and about half the next day. I couldn’t eat, sleep or drink. I know it says some sensitivity can happen but I was not in for the painful ride these white strips took me on. I get flashbacks of that pain and it makes me cringe so hard.    -
