I almost hate to say it – better than my Water Pik
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.

Great combination tooth brush and flosser
I only have one outlet in the bathroom and ordered this because it holds both the toothbrush and flosser. Both work very well and doesn’t take up much more space than just my Sonicare toothbrush. I really like that it has different modes and different levels so I can tailor to my needs, just as increasing/decreasing the pressure. The instructions are easy to follow. Even though I brush and floss everyday, I wanted something to get even more stuff from between my teeth and gums. My teeth/gums feel really clean.

Happy Customer!
Philips Sonicare Power Flosser 7000 was a great purchase for me! I had a broken tooth and had to wait 2 months to see an oral surgeon. The power flosser did an amazing job at keeping the area of the broken tooth clean. Powerful enough to remove debris and gentle enough as to not cause pain. I do use it twice a day on most days and I do feel like my teeth are cleaner. Planning on buying more as Christmas gifts for our adult children. Oral health has such a huge impact on overall health!

Worked for a little over 6 months and now it doesnât.
REVIEW UPDATE: I am updating my 1-star review to a 4-star review because the company reached out and sent me a replacement flosser like the one I ordered free of charge, as it is covered by warranty. As to be expected my original warranty remaining is the amount of time I have left on this replacement model, so I hope to get another 6 months out of this one. I donât have very high expectations as this style flosser just seems to be prone to leaks. However Iâm glad the company was able to make things right. I shipped my old flosser back to them so hopefully they can improve their quality. The company provided me with a free return label. 4 stars, as a $150 flosser should last longer than 6 months.âââââââââVery disappointed with this water flosser. I reached out to the manufacturer because the item was leaking and no longer maintained pressure and they informed me the product is out of stock but covered by warranty. I donât feel thatâs the case at all as it looks like this product line has been discontinued. I feel their attempt to replace this item with a half priced model is not a sufficient compensation. I will update my review if their customer service department is able to make right by this. I have a gum condition that requires me to use the flosser and being without it for over a month is not helping me with their faulty product. I think itâs fair to expect a refund or to issue me a new flosser of the same price point. For the money, this should have worked longer than 6-7 months.

Recibà el producto empacado en una vil bolsa de plástico. NO lo he probado pero la primera impresión de Philips asà es pésima. Espero funcione el producto sin problema …Nunca más voy a comprar algún producto de PHILIPS …No duró ni un año ya que se descompuso a los 10 meses de uso. La peor ducha dental que jamás he comprado

I was debating between the 5000 or 7000 and I’m glad I got the 7000.The extra large water capacity, hinged lid, auto-off, extra modes, “travel” nozzle storage, and the extra sensitive tip makes it well worth the upgrade.I got this water flosser to replace a handheld battery powered waterpik, it was combersome to use as I had to use it upright and the water lasted only 60s or less. This Sonicare water flosser can have the wand be oriented at any angle, is plugged in, and for my usage with lower water pressures it lasts in the minutes.I’m a bit concerned about the leaking within a year, but that’s still within the Philips warranty so I’ll go through their manufacturer warranty if it happens. The pros outweigh the cons so I didn’t hesitate to buy the unit despite the worrying reviews.

I have been waiting to write this review but first I wanted time to experience the flosser with it’s various features and nozzles. Now that THAT has happened, here is my review. I should tell you that I have used a WaterPik flosser for many years. I always thought that WaterPik had the edge over water flossers UNTIL I tried this Philips water flosser.I got to tell you that I can’t say enough good things about this 7000 model. The first and most important to me was the quietness of the water pump. I now can floss late at night without waking up the house. This model has all the bells and whistles: 4 modes, 3 nozzles, 10 intensity settings, a 30-second pacer (if desired) that indicates when you should move to the next quadrant of your mouth, Pulse-Wave Technology for two of the modes, Magnetic Docking for the handle when not in use, a 600 ml reservoir with a hinged lid, control of the water flow on the handle.The first three modes: CLEAN, DEEP CLEAN and SENSITIVE are used to remove food particles from around your teeth. The fourth mode, MASSAGE is to use water in a gentle flow to massage your gums. All the modes are wonderful so it is really a matter of personal choice as to what you prefer at any given session. The nozzles: the Standard nozzle ejects water like any water flosser, the Comfort nozzle is quite unique in the sense that it can touch your tooth and not slide off, as the rubber end acts like a brake for an exacting wash, the Quad Stream nozzle works similarly to the Comfort nozzle because it has a rubber tip as well but the squirting pattern is in four directions at once. I am NOT convinced that the Quad Stream nozzle is BETTER than the other nozzles, just different.I should also note the three nozzles come in a very practical plastic case with the intent to store them in the case between flossings.The Pacer, which essentially is a timer that indicates that your 30 seconds are up and time to move on to the next quadrant of your mouth. The indication is in the form of a 1-2 second pause of the water pump as opposed to an audio beep. Personally, I turned the pacing feature off.Having a hinged lid on the reservoir ….. I really hadn’t thought about it before as the WaterPik units have a detached lid or cover. But I actually close the lid when I am flossing now because I believe it keeps the water at a stable temperature without cooling.And finally, the Magnetic Docking of the handle is a really cool and simple feature. Click and it is attached to the unit.In some of the other reviews I have read, people have mentioned water leaks. I have not experienced unintended water leaks from the handle, the hose or the reservoir. Mind you, I use ALL 600 ml of water each flossing and wipe everything dry until the next time as opposed to some who leave a supply of water in the reservoir so they don’t have to keep filling it. Whether that contributes to leaks, I have no idea.When you are done flossing, detach the nozzle, blow out any drops of moisture and store it in the case. Shake out the handle in the sink ….a couple of drops of water may come out ….wipe the handle and the reservoir dry until next use.Anyways, as you can conclude, I am TOTALLY happy with my purchase. It truly DOES blow WaterPik away and the manufacturer has a two-year warranty.

Unfortunately like some reviews said here, the machine has quality control issues. It broke down just after 7 months. It stops working – no more spray of water. The motor runs, no leakage of water or physical damage. Disappointing product for the price point.
