Waterpik has the reputation of being one of the top water flosser manufacturers in the world, and their WP-660 water flosser is one of their bestselling products, so our review of it should hopefully see many positive and beneficial features.

Waterpik WP-660 Electric Countertop Water Flosser

This is one of many water flossers that Waterpik has manufactured, and as with most of the others, this is one of the bestselling products of its type. On sites like Amazon, it has over 16,000 reviews, and to its credit is still one of the highest-rated water flossers.

The first version was released in 2013, and this updated version in 2017. The newer version has more flossing options and many customers who had the previous version, give the new one lots of praise.

It is a countertop flosser, which means it is powered by electricity rather than by battery. Its main function is to water floss teeth via jets of water which are pumped from a water tank, and out through flossing nozzles which you place against your teeth. The principle behind its appeal is that the water jets can remove food particles, to provide the same dental health benefits as ordinary dental floss.

Who is this product for?

As this is a countertop flosser, the first thing to advise you is this is not suitable for those who wish to travel with a portable water flosser, unless you are prepared to pack it. Even if you do, as it requires electricity, where you are staying will need to have a suitable power outlet.

Given the large water tank, it is suitable for those whose daily oral hygiene routine is thorough. Thanks to the three standard flossing tips, it will also suit households where there is more than one person who wants to water floss their teeth.

What's included?

As with many water flossers what you receive could be described as a water flossing kit. The main item is the 'Aquarius' WP660 water flosser. In the package there are 7 flossing tips which are as follows: 3 x standard flossing tips, 1 orthodontic tip, 1 plaque seeker, 1 x 'Pik’ pocket tip, and 1 x toothbrush tip.

Overview of features

One of the advantages a countertop water flosser like the WP-660 has over portable ones is a larger water capacity in the form of a tank. In this case, it holds 22 ounces which means the need to refill it as often does not apply.

There is no shortage of flossing options, in terms of the water pressure settings. You have 10 to choose from, which range from 0 psi, up to 100 psi, depending on how rigorously you wish to clean your teeth. To select any one of them, you simply turn the dial to the setting you want.

Giving you further options is the different flossing tips that Waterpik includes with this water flosser. There are seven of them which include 3 standard tips, a plaque remover, an ortho tip, which helps those with braces use the water flosser, a toothbrush tip, and a periodontal pocket tip. For convenience, two of these can be stored on the unit.

How to use it

The operation of the Waterpik WP-660 water flosser is very easy. First, you fill the water tank with water from the tap. This should be warm water, but you can use cold if you prefer. If you want enhanced mouth freshness, you can add some mouthwash. Once the tank is secured on its base again, select and fit the nozzle tip you are going to use.

Select the pressure mode you plan to use and place the tip of the nozzle into your mouth and against your gumline. Close your lips to avoid splashing and then switch on the water flosser. To floss, slowly move the nozzle tip along your gum line, remembering to pause between teeth. Continue until all your teeth have been cleaned.

Alternative

While the Waterpik WP-660 is an excellent water flosser, there are others, who might not have their brand reputation, but which offer as good, and in some cases, enhanced features. One such product is the H2ofloss HF-9 Countertop Dental Water Flosser, which is an upgraded version of their top-selling HF-8 model.

It has 6 water flossing settings for variable water pressure, and whereas the Waterpik WP-660 comes with 7 interchangeable flossing tips, the HF-9 beats it with 12 tips. The HF-9 also has a water tank that has a water capacity 30% bigger than the WP-660 and thus there is even less need to keep refilling it.

Conclusion

For those serious about their dental health and who wish to add water flossing to assist the care of their teeth and gums, the Waterpik WP-660 water flosser is a top choice. It has plenty of options for you to utilize as well as additional nozzles for enhanced dental hygiene.

With this product coming from a manufacturer as popular as Waterpik, it should also give you the confidence that this is a quality product, which should be heightened further by the 3-year warranty they provide.
