AutoBrush is a nice tool to help clean the teeth. Saw my Grand children were using them and thought it might be something I could use. It has a timer so the vibration continues for 30 seconds. I must admit, IF YOUR DENTIST TELLS YOU THAT YOU HAVE A SMALL MOUTH YOU NEED TO ORDER THE TEEN SIZE HEAD. I do use the adult size AutoBrush Head because that what the order came with, but when in need to replace the head I will order a smaller size. For now I have to just my jaw while the AutoBrush is in work mode. Just a bit of advise, read how to apply toothpaste. I used too much the first time and was foaming toothpaste out the mouth during the first use. It does leave the teeth feeling clean, like after you leave the dental office, but without the grit from polishing. Highly recommend for children, because we know how they brush (sideways instead of up and down, and not long enough to get all the gunk out)
