Dentist recommendation, I think this water pic works very well and has done a great job keeping my gums clean and I have less plaque then ever before. I am looking forward to my next dentist cleaning appt. Hopefully they will be just as impressed as I am. I am telling others to purchase a cordless water pic they are the best.
We have not had dental checkups since the purchase, however, our teeth feel better and cleaner plus eliminating dental floss and a cleaner bathroom mirror.
