Title: BURN MY GUM!!!
Review: I'm Asia and my teeth is a bit yellow. So I decided to give it a try because it's so cheap. I bought this from walmart since it's much cheaper ($5) there. I applied the gel first time this morning and it was ok, my gum hurt a bit. However, when I reapplied it again this evening, it burned my gum even I did carefully wiped any gel out. But once the gel touched my gum, it burned my gum and hurt so much. I couldn't endure it even one minute. Now my gum is white and swollen. I don't know if it will work but I won't try it again. Please consider before buying.
