I bought the Sonicare for my husband a couple of years ago. It's brilliant.

It tickles your gums to start with, but with regular use this sensation disappears. It's very simple to use and very effective. You won't ever want to use any other kind of toothbrush again, your teeth feel so clean after using Sonicare.

There can be a slight problem of splatter if you don't keep your mouth closed,(hubby). Although I know how to keep my mouth shut (at times) and I don't really have a problem with it, although I often brush while in the shower.

We'd tried lot's of other whitening products as we're heavy tea drinkers and smokers. My husband's teeth in particular needing regular sandblasting!! We even had a mini tooth polisher, but I suspect that the paste was abrasive which just puts you back to square one, as with some other poducts, abrasion can leave a rough surface on the tooth for new stains to stick to.

There is no real downside to the Sonicair, except for suspicious glances from the unitiated, you can hear the vibrations quite clearly, and guests in your home may suspect that your facial expression isn't because you're grinning to showing off your shiny white gnashers!!
