I "almost hate to say it" because, decades ago when I was a teenager, my mother bought me the very first Water Pik model ever made to clean my metal railroad track braces. I've been a daily, loyal user ever since.
Because I was at a boarding school at the time, I saw the struggles of the other boys who had braces too: flicking with their toothbrushes, getting floss caught in the hardware on their teeth, with little luck. In two minutes, I had all the food blasted out of my braces. The only thing that felt better was finally getting my braces off.
But I kept using it, to this day amazed how few people know about, understand, or are interested in water flossing. It's one of the greatest dental inventions ever, and everyone should do it. After many years, Water Pik was able to print on their box "50% more effective than flossing". I have no doubt that's true. I have tooth gaps that yield an astonishing amount of food every night stuck in there, all released and down the drain with water flossing. Which means: food NOT sitting in there and fermenting against my teeth and gums. Follow up with (electric) tooth brushing and you've done about the best that can be done.
For a few years in my twenties, I slacked off completely, ignored dental hygiene, and things got bad. Canker sores, the whole nine yards. The only dentist I went to back then was so alarmed he said: "Come back when you have gums again", and told me to brush and floss vigorously before he'd do any other work. I got back into the Water Pik habit and, more than forty years later, my current dentist rates my gum health as very good. (I looked it up: the majority of people my age have gum disease of some kind. Plus, gum health contributes to bone health. I now have four dental implants. You can't get those unless you have the bone to support them. It's all intimately connected.)
Anyway, make no mistake: Water Pik is an excellent product and a pioneer company. They invented the entire idea, and kept going. But the unit I most recently had was finally getting decrepit (after a long, long time of nightly use). I looked carefully before simply ordering another. And decided to try the Philips Sonicare Power Flosser 7000. I am glad I did.
Powerful, remarkably quiet, convenient. (Note: I have NOT tried the newest Water Piks, so cannot directly compare.) It's actually nice, just before bedtime, to *quietly* water floss. That may sound trivial, but low noise does help for staying in a relaxed mood to get to sleep. I have been using it for a month, and am very pleased with the nightly results. The water pressure dial is great, easy to use, and "goes up to 11" if you like the full blast. (I do. Good gum massage.) On that setting, it will blast way harder than my previous Water Pik. Go gentler if that's your speed. The handle easily snaps magnetically into place when you're done, another convenience for less fuss.
My personal tip: mix warm water with hydrogen peroxide. If you have the standard 3% hydrogen peroxide, about 1/3 that + 2/3rds warm water is about right for me. Then water floss with that, and rinse. I'm convinced the resulting oxygenation helps suppress the bacteria that contribute to gum deterioration, and my dentist's approval of my gum health is at least some evidence of that. Peroxide has long been used as a "mouthwash". (Like any mouthwash, just don't swallow it.)
Dental health, the daily job. Believe me when I say: water flossing is a huge convenience, and this product is a first-rate device for getting it done better and faster.

HONEST REVIEW! Philips Sonicare!

Reviews with images
highly rated and I like it too
Before I bought this, I did research online and everything pointed to this Philips 7000 power flosser being the best for me as I have no countertop space limitations, not that it takes up much space. Then my daughter's dentist said it was time for braces, so before I even got my flosser out of the box, it went to my daughter. Because we have 50% custody, I bought her another for her other house. Paid for braces, saved up and finally the third Philips 7000 waterpick is MINE! I LOVE IT! It comes with different heads, I went with the purple one and it's the only one I've needed to use as it gets everything regular dental floss and dental tape can't get between my teeth. I have a gap in front of my last molar, and I'm always fighting with food getting stuck there that I can't get out with brushing or flossing. I am so very happy with this. I hope my review helps someone else.
