I bought this less than a month ago, hygienist recommended it... I love it, at first I was a little fearful, but it's simple to use, and the results are amazing!!! It feels like I just had my teeth cleaned at the dentist ( each time) I now use it after every meal (unless I'm out and about) You'll really see & feel the difference
My dental hygienist recommended this to me as I have some issues with the bone under the gums around my upper and lower molars. This has helped reduce the pain and, after a few uses, was easy to use.
