Teeth Whitening Gel : So simple and works instantly

After looking through all the teeth whitening options I opted for this because I've never had very good results with whitening strips (they never stick for the full time required and hurt my gums) and it seemed like the easiest thing to incorporate into my daily routine. Just add equal parts gel and toothpaste and brush for two minutes. I did this twice when I got home and saw immediate results, at least a shade or two whiter. This morning I used it again and my gums felt a little irritated, I'm not sure if it's because of the gel or me brushing extra vigorously. Regardless, I will continue using it because it's working so much better and less messy than the charcoal powder I purchased and is way more convenient.
