Philips Sonicare Power Flosser Toothbrush System 7000 HX3921 40

I’m a dental hygienist and had always been sold on Waterpik brand, decided to give the Philips water flosser a whirl since I love their electric toothbrushes and I’m very happy I bought it. It’s a sleeker design, water capacity is perfect, very easy to use, love how if you need to stop in the middle of water flossing, you flip the switch on the handle and it also turns off the motor in the water flosser so it’s not burning it up. Amazing pressure. I feel it cleaned better than any waterpik brand I’ve tried. Doesn’t look bulky on the country. Also easy to travel with because the tank easily comes off making the water flosser not as bulky. 10/10 from this dental hygienist Read more

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. Read more

The Sonicare Power Flosser 7000, HX3911/30 worked great for 5 months then decided to retire to that great flosser in the sky. Yes, while the motor kept running, no water was being dispensed to the hand-held wand. The unit was not dropped and/or misused in any way. I did not expect this device to last forever, but a 5-month lifespan seems a bit unreasonable. I called the Consumer Care Support center on Sep 18, 2024 and spoke with a representative named Kathy. After explaining the details of my situation and having me complete some basic troubleshooting procedures she confirmed that the unit has malfunctioned and I was eligible for a replacement. Case number 60-0037401231. On Sep 26, 2024 I was contacted via e-mail from someone named Kaye at the Consumer Experience Team, Phillips North America stating that this product will not be available within the next month and there is no indication when it might become available. I was asked if I would accept the Philips Sonicare Cordless Power Flosser 3000 as a substitute replacement. This item currently sells for $69.96 on Amazon. The item for which I am seeking replacement is currently available on Amazon for $139.96. Needless to say I declined the offer to accept a dissimilar item valued $70 less than the item I purchased. I don't understand how Philips is unable to attain and send me the same model item I purchased and had fail after 5-months when the exact item is currently available on Amazon. Again, this product worked great during its very short lifespan. Perhaps someone else will have a better experience with the product itself and/or the Philips Consumer Experience Team than I did. For me, I'm done with Philips products and will consider this experience a lesson learned going forward. Read more

Overall, this is a good buy. I hated having a flosser and toothbrush charger on my vanity top at that same time. This combined those two into a smaller footprint. The only con is the water tank doesn't empty all the way like some others do. Not a big issue in the scheme of things. Read more
