The first impression

The scope of delivery and build quality of the Waterpik 660 are impressive. I was really pleasantly surprised when I unpacked it.

Waterpik WP 660 Test

For one, the station of the oral irrigator with the attached water tank makes a very compact and stable impression. In addition, you get in the package equal to seven different attachments, with which you complete the cleaning of the oral cavity even more effectively.

To set up the device, you need some space in the bathroom. Keep that in mind even before you buy.

Before you start using it, you need to fill water into the removable tank. I like to use warm water for this, as it makes cleaning much more pleasant.

What functions does the oral irrigator offer?

An oral irrigator works with water, which cleans the oral cavity with pressure through different nozzle attachments. So the water pressure and the functions of the attachments are important to be able to evaluate an oral irrigator.

The Waterpik 660 features the following functions:

  • 2 function modes: oral irrigator and massage
  • 10 water pressure settings
  • 7 attachments
  • Also suitable for braces, implants and crowns
  • Size of the water tank: 650 ml
  • Timer
  • Power supply: Mains operation

2 Function Modes

A pressure switch on the station of the oral irrigator allows you to switch between two functional modes when using the Waterpik 660.

  • In “Floss” mode, you can use the water jet for cleaning.
  • In the “Massage” mode, you can additionally massage your gums with a varying water jet.

Even if you mostly use the Floss function during regular tooth cleaning, it is still practical to deliberately massage your gums once in a while. Such a massage promotes blood circulation and ensures healthy gums.

10 different pressure settings

Using a rotary dial on the station of the oral irrigator, you can regulate the pressure level of the water pressure when using it. Here, I recommend that you start with a weak pressure level first and then slowly increase it.

Increase the pressure slowly so you can get used to the stream and not cause yourself pain.

This way, you can quickly find the pressure level that suits you best while providing the best brushing results.

Using the rotary switch on the station, you can regulate the water pressure very easily on the WP 660. If you turn the knob all the way to the right to position 10, you have 6.2 bar of water pressure available. This is truly remarkable for a device in this price range.

Note: In principle, you should use the higher pressure levels (8 to 10) rather for really stuck food residues. For normal cleaning, less pressure should be sufficient.

7 attachments for cleaning

The Waterpik 660 comes with a total of seven nozzle attachments that add many important nuances to the cleaning experience. Even top-of-the-line devices in the highest price range don’t offer more attachments.

Which Waterpik 660 nozzle will be your favorite? Depending on your needs, you will surely find a suitable nozzle from the total of 7 included attachments.

These attachments are included with the WP 660:

  • 3 classic cleaning nozzles: you can remove plaque with these nozzles. Depending on how much pressure you use in the process, you can also thoroughly clean the interdental spaces.
  • 1 orthodontic nozzle: perfect if you wear braces.
  • 1 brush: a normal toothbrush attachment.
  • 1 Plaque-Seeker: These special nozzles refine the water jet and help remove even particularly stubborn plaque.
  • 1 Pik-Poket: special attachment for cleaning periodontal pockets.

The various attachments make the WP 660 oral irrigator versatile. Even if you don’t need all the functions all the time, it’s good to know that you already have the appropriate nozzles at home just in case.

Water tank and hose

The water tank of the WP 660 oral irrigator holds 650 ml. According to the manufacturer, this is enough to operate the oral irrigator for a maximum of 90 seconds. Since a normal cleaning process is one minute, so you still have a little reserve, if you want to clean in some places more sustainable.

mouth rinse mouthwash

You can also use mouthwash for oral irrigators like the Waterpik WP 660.

The water tank is removable, which makes it very easy to fill before each use. Here you can use pure water or mix the water tank with an additional portion of mouthwash.

Unlike mobile oral irrigators such as the Sonicare Airfloss, the Waterpik 660 is a stationary oral irrigator. Therefore, when used, the handpiece is connected to a hose. So note that the range of motion when cleaning is more limited as a result.

Timer function

The WP 660 has a built-in timer that sends you a signal after one minute to let you know that the regular cleaning cycle is complete.

In addition, there is already after 30 seconds a first signal. This is to help you clean both the upper jaw and lower jaw for an even amount of time.

I found the timer very helpful when using it.

Power supply

You need to plug the station of the oral irrigator into the mains for operation. If you have not used an oral irrigator before, you may find the operating noise of the water pump loud at first. However, after a few days you will get used to the operating noises.

Technical data

For those who like to compare devices based on their technical data, here is an overview of the WP 660’s data:

  • Dimensions: 26.29 x 11.93 x 9.65 cm
  • Weight: 1 kg
  • Maximum water pressure: 6.2 bar
  • Water tank: 650 ml
  • Pumping frequency: 1,200 pulses per minute
  • Material: plastic
  • Pause button on the handle

Overview of advantages and disadvantages

The following features stood out positively to me about the WP 660:

  • Very good value for money
  • 2 function modes
  • Water pressure can be regulated in 10 steps
  • 7 nozzle attachments included
  • Various applications

If I had to name a drawback, it might be the size of the device. The oral irrigator already takes up a lot of space in the bathroom. At the same time, however, this is also due to the water tank, the size of which I find positive.

Other model variants

The Waterpik WP 660 is available in a variety of colors. If you order the classic WP 660, you will get a white model. But there are also models in blue and black.

This model is equipped exactly the same as the WP 660, only the color varies.

The black model of the WP 660 provides a different look in the bathroom.

Note: The colored variants of the oral irrigator are usually a little cheaper than the basic white model.

Follow-up costs

To ensure that your oral irrigator always remains hygienic and gives you a long time of pleasure, you should also think about cleaning the Waterpik.

For this purpose, a cleaning powder such as from Redesept is suitable. The powder is specially developed for oral irrigators and is easy to use.

No products found.

If you ever want to replace a single nozzle, you also do not necessarily have to repurchase the whole set of 7 nozzles. You can get individual nozzles, for example, on Amazon.

What are the differences with other Waterpik oral irrigators?

The American brand Waterpik is one of the most widely used brands in the world for oral showers. Other models have also been able to achieve very positive test results.

WP 660 vs WP 100

There are two major differences between its predecessor, the WP 100, which is also often praised, and the new WP 660.

  • The WP 100 has only one function mode.
  • The WP 100 has a storage compartment for attachable nozzles conveniently located in the lid of the water tank.

When you consider that the WP 660 is even a bit cheaper than the WP 100 on current offers, I would always recommend buying the new WP 660 when making a direct comparison.

However, since the WP 100 is also a very good oral irrigator, it is worth comparing prices.

WP 660 vs WF05-EU

The WF05-EU oral irrigator offers a few more interesting additional features compared to the WP 660. These are the main differences from the WP 660:

With the WF05-EU, you can achieve additional whitening of the teeth by means of special tablets that you insert into the handheld device of the oral irrigator. However, this special function is also reflected in a significantly higher price.

Conclusion: the Waterpik 660 gets a clear buy recommendation

With the current prices for oral showers, the WP 660 definitely takes an absolute top spot. It is not for nothing that it has been able to win numerous product tests very clearly in recent months.

  • With the Waterpik 660 you get a modern stationary oral irrigator, which is very versatile.
  • Within a very short time, you’ll notice that your gums feel healthier and plaque is a thing of the past.

Best practices for using a water flosser

Water flossers, also known as oral irrigators, are an effective way to clean your teeth and gums. It is a popular tool for people who struggle with traditional flossing or who have braces, crowns, or dental implants. While water flossing is easy to use, it is essential to utilize the right techniques and practices to maximize its effectiveness.

Firstly, it is important to adjust the pressure of your water flosser. High pressure may cause gum irritation, while low pressure does not provide effective cleaning. It is recommended to start with low pressure and gradually increase it to a level that suits your needs. Additionally, it is better to use lukewarm water than cold water, as cold water may cause tooth sensitivity.

Secondly, you must pay attention to the position of the tip of the water flosser. Avoid aiming the water stream directly into your gums or teeth, as this may result in pain and bleeding. Instead, place the tip of the water flosser at a 90-degree angle to your gums and teeth, allowing the water stream to reach the spaces in between your teeth and the gum line.

Thirdly, it is recommended to use a specialized mouthwash with your water flosser to enhance its effectiveness. Mouthwash can help to kill bacteria, get rid of bad breath, and clean areas that are hard to reach with a toothbrush or floss. Pour a small amount of mouthwash into the water tank of your flosser and use it like a normal flossing session.

Lastly, it is important to clean the water tank and the tip of the flosser after each use. This will ensure that you are using a clean and hygienic tool every time, preventing any bacteria or mold growth in the water tank that could cause potential health issues. Follow the instructions provided by the manufacturer on how to properly clean your water flosser.

In conclusion, following these best practices will make sure that you get the most out of your water flosser. With regular use and proper care, a water flosser can provide excellent oral hygiene, reduce inflammation, and protect your teeth and gums from various dental problems.

Comparison of water flossers to traditional floss and interdental brushes

When it comes to oral hygiene, flossing is an essential part of keeping your teeth and gums healthy. Traditionally, dental floss and interdental brushes were the most commonly used tools for flossing. However, in recent times, water flossers have become increasingly popular. Water flossers, also known as oral irrigators, are devices that use pressurized water to clean between the teeth and along the gum line. Let’s take a closer look at the benefits and drawbacks of each method.

Traditional floss is the most well-known flossing tool. Dental floss is a thin string made of nylon or similar material, which is inserted between the teeth and wiggled to remove plaque and food particles. It is effective in cleaning tight spaces between the teeth and is readily available in drugstores and supermarkets. Although traditional flossing can be time-consuming and requires a certain amount of skill and dexterity, it is the most affordable and widely available option for maintaining dental health.

Interdental brushes resemble tiny toothbrushes and can reach the spaces between teeth to remove bacteria and debris. They are available in many different sizes to fit the spaces between all types and sizes of teeth. Interdental brushes have a handle for easy gripping and bristles that vary in size, allowing users to get into the tightest of spaces for maximum cleaning. Although they offer better accuracy than traditional floss, they can sometimes be less effective, as their bristles can’t always reach underneath the gumline.

Water flossers use water to powerfully and effectively remove food particles, tartar, and plaque from teeth and gums. They work by using a stream of water that shoots between the teeth, removing debris from hard-to-reach spaces. Water flossers can be especially helpful for people with braces, and those who struggle with manual dexterity. Some models even have multiple tips for better cleaning, which can be personalized to the user’s needs. One downside of using water flossers is that they are generally more expensive than traditional floss and require a power source.

Overall, the choice between traditional floss, interdental brushes, and water flossers will depend on your dental needs, personal preferences, and budget. However, regardless of which method you choose, remember that flossing is an essential part of maintaining proper oral hygiene.

The benefits of using a water flosser for oral hygiene

As an enthusiast in the field of oral hygiene, I am always excited to explore new tools and techniques to improve my dental health. One such tool that I have recently discovered is the water flosser. A water flosser is a handheld device that uses a strong stream of water to remove plaque and food particles from between your teeth and along your gum line. While traditional flossing is still an effective method, the water flosser offers several unique benefits that make it an excellent addition to any oral hygiene routine.

First and foremost, using a water flosser is incredibly gentle on your teeth and gums. Traditional flossing can often cause irritation or bleeding, especially if you have sensitive gums or orthodontic appliances, like braces. With the water flosser, the stream of water is much gentler and less abrasive, so it’s much less likely to cause these types of issues. Additionally, the pressure of the water is adjustable, so you can customize it to your individual needs.

Another benefit of using a water flosser is that it’s highly effective at cleaning hard-to-reach areas around your teeth. While traditional flossing is great for removing food particles and plaque from between your teeth, it can be challenging to reach some areas, like the back of your mouth or around dental appliances. The water flosser’s strong stream of water can easily reach these areas and remove any debris, improving overall oral health.

Finally, using a water flosser can help improve bad breath. By removing food particles and bacteria from hard-to-reach areas, it helps prevent the buildup of plaque and bacteria that can cause bad breath. With regular use, a water flosser can be an effective tool in maintaining fresh breath and dental health.

In conclusion, there are several benefits to using a water flosser for oral hygiene. It’s gentle on your teeth and gums, highly effective at cleaning hard-to-reach areas, and can help improve bad breath. Whether you’re looking to upgrade your oral hygiene routine or simply want to try something new, a water flosser is definitely worth considering.
