There is a low and high speed.... no matter where I set it, it only gives slow speed. Wonder if it is doing any good. Should have purchased a stronger spray product
In March I had a bridge put in my mouth. This was the first bridge I ever had, and I could never get used to using a floss threader. The Waterpik cleans under the bridge whereas the threader was useless. I still floss all of my teeth because I have doing so for decades, but the Waterpik puts the finishing touch on my dental hygiene, especially with the bridge.
It works like it is supposed to BUT I have found that if its not convenient, it won't get done. Using a waterpik is a messy job. It is best done in the shower. This one is not waterproof enough to take in the shower. Also, one filling is not enough water to do a good cleaning. At least three is needed. Looks like I wasted my money and back to regular flossing. I had high hopes.
No, I would not recommend this to a friend.
