I have dental implants and my dentist suggested getting a waterpik to get between the implants and the gum line. The first time I used it I couldn't believe how much food particles it dislodged. This will greatly help with my dental hygiene!
I got it due to some periodontal issues, and my arthritis in my hands makes it hard for me to handle floss. I like how I can control the pressure of the stream, and I never mind having to use it!
