First time I used it, DID NOT HAVE IN MOUTH.....sprayed entire bathroom wall down. That's OK. My bathroom got cleaned. Took a few attempts but I think I'm using it properly now. Just hard to navigate it in the correct places around the teeth and gums without looking in the mirror, or else the mirror gets sprayed. I'll rate the product after my next visit to dentist.
Our dentist recommended that we buy this product and we are very happy we did. We purchased about a month ago and had never previously owned a waterpik before. I flossed everyday prior to this purchase, but I must say that the waterpik flushes out small particles that I wasn't able to get with the flossing. Teeth feel cleaner and seem to look whiter after doing this. We're hooked.
A quick and complete flossing, daily, at last! Just five minutes, and my teeth feel clean, and gums are attended to regularly. Can't wait for dental hygenist's reaction at upcoming appointment for professional cleaning. Gave it a four, and not a five only because of the water dripping on clothes and learning curve in using it.
My husband and I both love this water pik. It's easy to use and the instructions were easy to follow. I was having trouble cleaning my back molars at the gum line. Not any more! Every day my mouth feels like I just walked out of the dentist office...maybe even better!
