Query: Like a massage for your gums

My dental hygienist also gave me one of these to try, and they are great. The soft rubber hairs sticking out from from the very thin soft rubber pick feel good as they glide across your gums. And they work, my gums are much more healthy. I keep one at my desk and absentmindedly use it while reading emails or on conference calls.If you are careful, one pick can last a week.
