I'm 79, still have all my teeth and no dental work. 6-month checkups involved lots of tartar removal and that wonderful clean teeth feeling for a few days afterwards. Then the hygienist suggested I get a Sonicare and I did. Great suggestion because now my teeth have that smooth, clean feel all the time.
It's pretty much okay. Sometimes it doesn't work right after it's been charged. Actually I liked my FlexCare one better. It always worked until it finally died and was much less expensive. I'm also not crazy about the glass charger. It's a pain if you want to take it when you travel.
