good check-ups w/ this toothbrush!
Most of my family have been using this toothbrush (the sonic variety of the oral-b vitality) for about a year, & we're very happy w/ it.  & so is my dental hygienist...I missed my last appointment, so it's been 18 months between cleanings, & there was very little build-up.  the replacement heads are a bit hard to find & a bit pricey, but I found some on Amazon for about $16 for a 3-pk, which is about 2/3 the price elsewhere.  So I purchased this one at Amazon for my son.
