if you are a non-dentist, i would advise against it/. since you could do alot of damage to teeth, better of having a dentist clean it. most of the reviews on sites that sell these have customers complained it damaged thier enamel permanently, because they do it aggressively. same goes for whitening your teeth, people do it too aggressively. i almost bought one once until i saw the reviews, yikes, because you have to use a mirror to see your teeth while doing it, and might not know if that is tartar or just staining.
What about those ultrasonic cleaners for tartar? That is pretty high-tech.
