Title: Great toothbrush
Review: Not much to say that others haven't said already. The tooth brush works great. I have noticed a significant improvement in whiteness and overall clean feeling.Also, I use a Swedish smokeless tobacco product which can cause rough patches on the gums and yellowing between the teeth. A completely unexpected benefit, this toothbrush eliminated both problems within a week.
