Review (3/5): :/
today was my third day using them...the first day was not bad. the second day i started feeling pain, and today OH GOD!!! its horrible. i feel like crying from how much my teeth and gums hurt! today when i put on my second round of strips, i felt REALLY BAD pain in my lower gum like almost a burning sensation, and very irritating...so i moved the strips around and moved them off that spot...i was still in great pain. when my 30 minutes were over i noticed that the spot on my gums where i felt a burning sensation, the whitening gel indeed did burn off that spot on my gum and i was bleeding. now im experiencing the worst pain EVER!! :[ im going to the dentist tomorrow because im scared of what it did to my gums and teeth after only 3 days!
