Query: great for kids with braces!

I have been a practicing dental hygienist for 26 years. We are now learning how the waterpik can be a very effective tool in home oral hygiene. Kids with braces face unique challenges. If they don't brush well, they will be left with a mouth full of cavities. Most kids don't brush above the brackets, near the gums. The waterpik tip I use has a brush and sprays water so it removes the bacteria without being uncomfortable. In fact, they love using it cuz it is fun! Our last visit to the orthodonist was met with rave reviews on how clean their teeth were. Adults can use it to!
