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.

By M. Erb #1 HALL OF FAMETOP 10 REVIEWERVINE VOICE on October 24, 2011
Size: Ultra Verified Purchase
Length: 3:55 Mins
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.

We actually have liked this product and used it for more than two years. However, recently when changing the tip I noticed black particles coming out of the hand-held wand bulb. I then hit this plastic section against the sink and dislodged a considerable amount of additional black material. I felt it was then important to break open this plastic bulb section - the part you hold in your hand - and found it full of black colored mold! In my opinion this is a serious design flaw. Since this section is not sealed, it should be possible to clean it. Yet, in the Waterpik manual, you will find no instructions on how to do this, or that it is even necessary. I have read one third-party article that recommends periodic soaking of this plastic bulb in vinegar. However, there is no a way to assure that it is clean, without breaking it. It does appear that any mold in the plastic case of the hand unit may not contaminate the water spray into the mouth, however, the proximity of mold growth so close to mouth is, in my opinion, unacceptable.

I called Waterpik to advise them of my concern, noting that, while we don't seem to be allergic to mold, many people are and this section of their device should 1) be re-manufactured to allow opening and cleaning and 2) cleaning procedures should be published in their manual. Obviously, we have discontinued using the Water Pik. To their credit, the company has responded by email and is, apparently, now looking into this matter. They have offered a replacement unit and we have declined.

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.
