Query: A Dental Must

While we are all told to use dental floss daily, nothing comes close to this water flosser. I use this in conjunction with regular floss and an amazed what the regular floss misses this the water flosser is able to get. Your mouth and gums will not only feel more clean, but it will be cleaner. Add a little mouthwash to the water tank and you will have a party in your mouth. LOVE THIS FLOSSER!!!!
