This works wonderful with the toothpaste. I wish it came in a bigger container, I will go through an entire container in a week by myself. But other than that, I don't have any problems. Before using this, I wasn't much of a mouthwash person. It was more of a brush and go regimen. Now I'm brushing twice a day and feel more confident in my smile. My Mom even noticed how white my teeth have been getting and decided to switch brands herself.
