The Easy and More Effective Way to Floss

The Waterpik Water Flosser is the easy and more effective way to floss. And it's perfect for anyone with braces, implants, crowns, bridges, or periodontal pockets. Water flossing for about a minute a day comfortably removes up to 99.9% of plaque from treated areas as it gently massages the gums to improve overall oral health. Waterpik Water Flossers are the only brand clinically proven to be up to 50% more effective than traditional dental floss and up to 80% more effective than Sonicare Air Floss for improving gum health.

10 Water Pressure Settings for Healthier Gums

Whether you prefer gentle water pressure or deep cleansing, the Ultra Water Flosser's 10 adjustable water-pressure settings give you optimal control. Select a personalized setting between 10 to 90 PSI with 1,400 pulses per minute to keep your gums healthy. The Ultra Water Flosser cleans deep between teeth and below the gumline, while massaging and stimulating the gums. Clinical studies show that when used regularly, the Ultra Water Flosser gives you healthier gums in just 14 days.

Improved Design is Quieter and Ergonomic

The Ultra Water Flosser's improved design features a high-volume, covered reservoir with an in-lid tip storage compartment. It is also smaller and quieter than previous models. And its ergonomic handle design is comfortable to hold and offers a convenient pause button.

UPDATE: 1/24/2014 - Waterpik has a new model, the Aquarius Model WP660C, Waterpik Aquarius Professional Water Flosser, White Satin Base with Crystal Clear Reservoir. It's been updated with a few new features. It has a gum massage feature and to help you pace your flossing it pulses at 30 and 60 seconds. It runs for 90 seconds on a full tank at the highest pressure setting. The WP-100W has a clunky storage space on the top for storing the tips and the WP-660C does away with that while allowing the storage of two tips between the reservoir and body of the waterpik. It is much lighter in weight (not sure if that's good or not) and is attractive in a waterpik kind of way. You may want to consider checking out my review of the WP-660C before making your decision on which to get. I actually prefer this Ultra WP-100W in spite of the new features of the Aquarius WP-660C


I'm very pleased with this Waterpik Ultra WP-100W water flosser. Prior to this I owned an Interplak Dental Water Jet, 1 each and I was quite happy with how long it lasted. That one lasted 3 years with daily use and started to leak at the handle so I decided it was time to buy a new one. Unable to locate the same thing locally, I decided to purchase the Waterpik WP-100 and so far I find it superior to the Interplak.

The Waterpik operates on 120V, 60Hz only.
Measures at the base 5.5" wide, 4.75" deep.
Cord length is about 54" which is quite generous.

It's got a small footprint so doesn't take up much counter space.

Size: Ultra
For near-dental quality ‘water-flossing’ I would say the Water Flosser (from Waterpik) is as good as you can get in an ‘at-home’ model. While there are many things about it that could be better (the plastic has a cheap feeling to it, the product itself is very light-weight) the improvements would likely raise the cost of this product by hundreds of dollars. For the price, this is as good as it gets.

While I have been really working hard to ‘beautify’ my smile for an upcoming wedding, I use the Waterpik as part of a healthy regimen of cleaning my teeth. It has 8 different attachments, but you really only need to use the 3 standard jets and the 1 attachment for deep gum cleaning. I’ve been using This teeth dental-strength whitening kit for the past few weeks in preparation for the wedding, and because of this, I was worried that my gums would be a bit sensitive if flossed too much. Luckily this unit has 7 different speeds, so regardless of whether or not you floss or if you’re trying to use different cosmetic whitening solutions this product will still work well. I’m happy to say that using this has helped me not only keep my mouth free of periodontal disease but has enabled me to floss with water while using the whitening product. My gums are still healthy as can be and my teeth are white as ever.

The one complaint I do have about this product is the hose is quite short. This means you have to have the product very close to the sink in order to use it. I would make sure to have an extension cord handy so this product doesn’t end up being a cumbersome task of plugging and un-plugging whenever you want to use it.

Size: Ultra
As far as "Water Piks" go this model is pretty snazzy and seems to work quite well. It comes with 8 attachments:

* 3 standard jets * 3 tongue cleaners * 1 pik pocket (cute name) for deeper gum purging and * 1 orthodontic tip (with small brush on end) for cleaning braces.

- The 'tongue cleaners' are worthless contrivances that simulate drowning.

You can clean your tongue much better with a standard tooth brush (although a coated tongue generally indicates the need for a dietary change, like more fruit, salad and less gunky foods).

- The orthodontic tip seems that it will work great for braces.

- The pik pocket (narrow tip) does not work as good as it should. Rather than increasing the water pressure the narrower tip actually slows it down. It may be convenient in some tight spots. It is good to have but seems to be of rather limited use compared with the standard jet tips.

The standard jet tips work quite excellently (4 stars) and will surprise you with how much junk is left behind by regular brushing and flossing.

- Most adult dental problems are caused by infrequent (below the gum line) professional cleaning and/or ignoring to floss. The Waterpik is designed to give you a significant 'edge' in keeping your teeth and gums in good condition by getting between the teeth and below (somewhat) the gum line to remove the 'left-behind gunk' before it turns into plaque, bleeding gums, and a myriad of problem$$$. Poor oral hygiene is the main cause of tooth-loss regardless of age.

- This "Ultra" model is powerful (100 watts) and does the job of power-washing your teeth and gums quite well.
