Title: Great Results, but there is some pain involved.
Review: This is my first time bleaching--I used 15% trays for about 8 days and noticed great results. Just be sure to avoid Soda or Coffee since that will stain your teeth. I will not lie, if you have very sensitive teeth, this may not be worth it to you since it hurts A LOT. But if you're willing to go through some pain for white teeth, more power to you. Ocassionaly, I felt pain in my nerve as if someone is poking a large needle to my gums. Drinking cold/hot liquids after the sessions was a bit hard since my teeth were quite sensitive. All in all everything was worth it. My teeth have never looked this white. Sometimes you have to pay a price for great results.
