Review (4/5): Works, but a little gum irritation
Have used this once a day for the past 3 days, and I have seen a slight difference.
The only reason it isn't getting 5 stars is because it is a little irritating at the gum line. I am using this with a soft tooth brush, and brushing gently per the instructions. And others may not have this same problem, but just a head's up for those out there who may have sensitive gums.
