I've had problems with my teeth bleeding at dentist appointments and while brushing. Dentist said it was worse last visit so I decided to try the brush and water pik instead of 2 separate items. After using the water pik/toothbrush I have noticed almost no bleeding, teeth feel so much cleaner. Can't wait for dentist to notice the difference. Wish I had gotten this before. More expensive then buying 2 separate items, but I feel it's well worth the price. I tell everyone to get this item and they'll see a big difference.
Sonic brushing cleans better than rotation heads or hand toothbrush so much. Compact size is small but still does the job. Prefer to have full size brush heads.
