If you already have a mouthguard I would recommend buying a double set of gel liners instead as just one set will do for upper or lower teeth. Initially, the bleaching gel burns the gums a bit, but it doesn't hurt. I think the mineralizing gel helps reduce tooth sensitivity and also helps restore gums. Mouthguard is usable but could be improved. I was concerned about tooth sensitivity when using whiteners but decided to try Watts Power White on my upper teeth. After using almost the entire tube for about 45 minutes and three times a week for about three weeks, my upper teeth were noticeably whiter than my lower teeth by about three shades. My canines were also slightly discolored compared to the other front teeth, but they are now about the same color. Now people notice my smile has gotten brighter. I would describe my teeth as pearly white but not super white as shown in the photo. I am working on my bottom teeth and will see if I can get super white teeth although they may have reached their limit.
