chemical burn. I use the 35% and always, always wait until 3 hours after I last brushed my teeth and dry your gums with a cotton ball and apply copious vaseline on your gums before you put your trays in. I used to have black burn marks from the bleach but now have done it 3x day for 1 week with the vaseline and my daughters no longer make fun of my "yellow corn" teeth. It does take 24 hours to see real results so brush immediately after having morning coffee and other stainers. White food for a week won't kill you :)
