WATERPIK 660 VS 670: Which is the Best Electric Toothbrush for You?


Is brushing alone enough? Maybe not! Hard as you brush, you still find stubborn dirt and plaque accumulating within your teeth and the gum after some time. This cannot be removed by merely brushing your teeth. In the same vein, daily brushing is not enough to give you sparkling white teeth and stronger gum. This implies that you require a stronger hygiene method to achieve these. The answer lies in a good flossing treatment.

But, you know what the good news is? Flossing has become so easy that you can do it all by yourself! You do not have to make endless trips to the dentist anymore. All thanks to the advanced digitized flossing equipment now available in the oral hygiene industry. However, if you are considering getting a piece of domestic flossing equipment for the first time, selecting the best one for you might be a chore because there is a handful of them out in the market. In this article, you will find a review of our top picks as far as flossing is concerned.

Waterpik 660


This water flosser, by all means, stands tall when we talk of devices for flossing. It is one of the most easy-to-use electric Waterpik Aquarius flossers and is highly sophisticated, effective and pocket-friendly. It comes with a handful of technological features that helps to remove plaque and stubborn dirt on your teeth and gum within a short period of constant use, and thereby preventing tooth decay and bad breath. Talk of one of the first water flossers to be approved by the American Dental Association!

A rotating flosser tip

Using the Waterpik 660 cannot be any more stress-free than it is already. The tip is designed to rotate at a complete 360° to make it easy for you to access the corners and interiors of your mouth. With this design, the tip of the flosser can reach in between the smallest space between your teeth and dig out all plaques. This way, no food particle whatsoever gets a chance to hide!

Easy Water Control

What more could we want in terms of convenience? The control button that regulates the flow of water through the flosser is situated right there on the handle where you attach your flossing tip. With this design, all you need to do in order to stop or resume the flow of water is to move a thumb and push the control button up or down each time, and you’re good to go.

Double Flossing Modes plus LED indicators

Did you know that you could control the cleaning mode on your Waterpik Aquarius 660? Yes! It is not rocket science. The design comes with a button attached to the unit, with which you can change the mode to suit your flossing at each point in time, be it for braces, plaques, brushing, or for periodontal pockets as the case may be. What’s more! As you switch the modes, there is a LED indicator to show you which mode you are on.

10 Pressure settings

In addition to changing the modes on your Waterpik Aquarius 660, you can also regulate the pressure while flossing. The flosser comes with ten different pressure levels from 10 to 100 PSI to suit your cleaning mode. This makes it necessary for you to control the pressure, and with the help of a single knob, you can achieve this.

Seven Tips for Multiple Users

This is perhaps one of the most vital reasons I love the Waterpik Aquarius 660 design. The fact that it comes with many cleaning modes and pressures isn’t enough. It also has seven different cleaning tips for multiple functions. About three tips for your regular flossing, and one each for cleaning braces, plaques, pockets, and an extra toothbrush tip.

1 Minute Timing

The recommended dental flossing duration is 60 seconds. Your Waterpik Aquarius 660 helps you achieve perfect flossing within this period. First, it comes with a built-in timer that tracks your flossing period. More so, the water tank is made to contain water for well over one minute.

A large water reservoir

Irrespective of the mode and pressure your unit is operating on, the water reservoir is built to contain and release about 22 ounces of water to serve you throughout your flossing period.

What We Like

  • Compact design and easy to use

One of the selling points of the Waterpik Aquarius 660 is its design. Although it is not particularly smaller in size than the previous Waterpik models, it sure has a unique design and a lot of added features that make it easy to use for individuals of all ages.

  • Multiple-use and multiple users

If you are looking for a single flossing unit that can serve your whole family, the Waterpik Aquarius 660 is exactly what you are looking for. It has seven different tips that can be used by different individuals but still with the same unit. All you have to do is attach your own tip to the handle each time you wish to floss, and you’re good to go!

  • Efficient for better oral health

TheWaterpik Aquarius flosser 660 is highly sophisticated efficient and has been tested and approved by the American Dental Association (ADA) for use. It is much more effective than mere brushing and the traditional flossing, as it removes plaque with about 99% efficiency.

  • Easy to store

It requires very little storage space and weighs less than 2 pounds. You can place it anywhere in your bathroom.

  • Three-Year Warranty

To wrap it up, Waterpik gives you a whooping three-year warranty on this trusted water flosser. At such a small price, you get double its value with added warranty period especially if you buy from online stores such as Amazon.

What We Dislike

  • It could get messy a lot.
  • It possibly loses pressure after some years.
  • A little noisy.

Our Verdict

This water flosser gives you an awesome oral cleaning outcome at a very low price. You will be grateful for its efficiency and for its ability to remove plaque especially. Whether yours is a dental implant or a natural set, the Waterpik 660 will serve you quite well.

Waterpik Aquarius 670


The Waterpik Aquarius 670 is a more advanced version of the 660 model. It possesses a number of technological features and cleaning accessories that combine to give you a flawless flossing outcome within the same duration of 60 seconds. You will also fall in love with its beautiful design that stands out among others. It is quite an excellent oral irrigator system for removing oral bacteria, plaques as well as particles. It has also been approved for use by the American Dental Association.

Double Floss Modes

Like the Waterpik Aquarius 660, this water flosser serves more than one oral cleaning purpose. In addition to the known flossing which helps to remove plaque, it also does hydro-pulse massage mode which strengthens your gum and keeps it healthy all round and protected from further contamination.

LED Indicator Panel

With the Waterpik Aquarius 670, you do not have to guess how long you have flossed or if you are applying much more pressure than necessary. The LED indicator panel on the unit shows you all the information you need to help you do it right and get the best cleaning outcome.

Timer

The standard dental recommended duration for flossing at each point in time is one minute. Most times, you could lose track of time and floss for only 30 to 45 seconds thinking you have been at it for long. This is often the case with the traditional flossing method. With the Waterpik flosser, however, there is no room for doubt because the time is shown right there on the LED panel for you to see, and to help you regulate your flossing.

Storage Case for tips

This is perhaps one of the few things that come with the Aquarius 670 but the 660 model lacks. In addition to the storage space underneath the water reservoir lid, which can only take two tips at a time, there is a special storage case built for tips, and can contain all seven tips at a time!

10 Pressure Levels

To ensure that the double floss mode is well regulated, and in order to avoid mess while flossing, the Waterpik Aquarius flosser 670 has about ten levels of pressure which can be adjusted to suit the mode and flossing purpose at each point in time. As a matter of fact, it is advisable to start from low pressure (10 PSI) and adjust to a higher one as you progress in the flossing process.

Extra Cleaning Accessories

Here is a water flosser that comes as a complete package. The accessories attached to it are quite essential for complete and successful flossing. They include the tip storage case, three classic jet tips, a plaque seeker tip specifically for removing plaque, an orthodontic tip, a Pik pocket tip, a toothbrush tip, as well as a pulse modulation technology.

What We Like

  • Highly effective flossing If you’re someone who detests flossing, here is your best shot! It makes the entire process easy and fun, and highly effective. Within two weeks of daily flossing, you would have noticed commendable changes in the outlook of your gum and teeth. It is as efficient for string floss as it is for implants.
  • Easy to regulate The Waterpik 670 is quite easy to operate and regulate. Once you have selected and attached your required tip to the handle, all you have to do is switch on the unit and regulate it using the knob attached. Apart from this, you can also regulate the flow of water using the switch on the handle.
  • Useful for large families This is also one of the highest selling points of the Waterpik 670. Based on the fact that it comes with multiple tips, it can as well be used by families with large members. All they have to do is assign a particular tip to each member, according to their flossing needs, and attach the tip to the handle each time they have to floss.

What We Dislike

  • The cord could stand in the way when flossing
  • The noise is on the high side and could be sometimes intolerable
  • A little too costly, compared to the previous models.

Our Verdict

Barring the heavy price, the Waterpik Aquarius flosser 670 is no doubt one of the best on the market. You will enjoy its advanced features and efficiency, and you will start seeing the outcome within weeks of using it.

TIPS TO CONSIDER BEFORE BUYING YOUR WATER FLOSSER

Selecting a suitable water flosser for yourself could be a little demanding and somewhat technical, but you could do with a little guide. In this section, we provide a few tips to help you through

  • Your oral hygiene goal Water flossers are of different types and for diverse multiple functions. In addition to the general use, which is flossing, there are specific uses and applications you should bear in mind. Such uses include plaque removal, periodontics, gum stimulation, and lots of others. If your dentist has recommended a particular flossing goal, ensure you bear it in mind while making a purchase.
  • Available specifications Some water flossers are richer in specifications than the others. Although the ones with more features could be costlier than the others, they help you to achieve your oral hygiene goal quickly.
  • Storage space in your apartment Generally, water flossers do not require much storage space, but if your apartment or bathroom is small, you might want to consider opting for a cordless flosser or a small one.
  • Your budget Perhaps this is the most important factor. Water flossers do not necessarily require much maintenance cost but some could be expensive to procure. Consider your pocket!

CONCLUSION

After all, said and done, you would have learned that the Waterpik 660 and 670 are awesome water flossers, both with over 99% efficiency. We recommend the Waterpik 670 for its amazing accessories, but if you’re short on cash, you should go for the 660 instead. Either way, you will have excellent oral hygiene within two weeks!
