    We used to buy he Oral-B system. My wife switched the family to the new Panasonic sonicare and our teeth and gum have an A+ bill of health from our dentist. Yes it is a little more than your average electronic toothbrush, but it all pays off when the dentist give you a thumbs up with your oral Hygiene. For maximum results, I recommend using a Water-Pick after brushing with a little bit of mouth wash mixed with the water pick...

    I’ve had an Oral-B alternative for the longest time and the dentist recommended that I switch to the sonicare. Because of the vibrating action, it’s a lot gentler and more effective on your gums.
