How Does the Waterpik Sonic-Fusion Work?

The Waterpik Sonic-Fusion 2.0 flossing toothbrush combines a sonic toothbrush with a water flosser

With the Waterpik Sonic Fusion toothbrush, users can floss their teeth while they brush. This combination helps to achieve superior oral health and eliminates the need for multiple dental cleaning devices.

The Waterpik Sonic-Fusion turns oral hygiene into an effective one-step process by: 

  • Eliminating more plaque
  • Reducing bleeding and gum inflammation
  • Cleaning hard-to-reach areas (that a regular toothbrush can’t reach)

The toothbrush has various cleaning modes and pressure settings. This feature allows you to customize the water pressure based on your preferences.

This device is rechargeable and includes a charging base perfect for a standard bathroom countertop. Waterpik offers a 30-day return policy and a 3-year warranty on the Sonic-Fusion 2.0 flossing toothbrush.

Features of Waterpik Sonic-Fusion

The new Waterpik Sonic-Fusion 2.0 has up to 2X the bristle tip speed as the original version. 

Other features include:

Brush Head and Handle

The Sonic-Fusion Waterpik toothbrush head has a built-in water flosser tip. This toothbrush head offers a high-low bristle pattern that gently brushes while the water flosser removes plaque and debris. You can purchase replacement flossing brush heads separately.

It comes with an easy-to-grip, lightweight handle that holds the mode buttons. This handle can also easily convert to a power brush for travel.

Irrigation Hose

The irrigation hose delivers the water directly into the brush head. With a 360-degree handle-end swivel, it’s easy to adjust to reach hard-to-reach areas. This hose is flexible and easily coiled, attached, and detached.

Delivery Unit

The delivery unit is stylish and easily fits on a standard bathroom countertop. It’s lightweight and stable, so it doesn’t tip over during use.

The delivery unit features ten different water pressure settings. It also has a vented fluid reservoir, so the unit air dries between uses.

Additional Features

Other features include: 

  • Over 60 seconds of flossing time
  • 2 flossing brush heads (1 compact, 1 regular) with covers
  • 2-minute timer with a 30-second pacer
  • 3 cleaning modes (brush, floss, brush and floss)
  • 10 advanced pressure control settings
  • Recharge indicator light 
  • Deluxe toothbrush travel case
  • Global voltage
  • 3-year warranty

How Effective is the Waterpik Sonic-Fusion 2.0?

The American Dental Association (ADA) and clinical studies have proven the Sonic-Fusion safe and effective.

One study found that the Waterpik Sonic-Fusion flossing toothbrush is twice as effective as traditional brushing and flossing in reducing plaque and improving gum health.4

Using a Waterpik also helps:

  • Remove plaque biofilm
  • Reduce gum bleeding
  • Reduce inflammation

Like all Waterpik Water Flossers, the Sonic-Fusion claims to remove 99.9% of plaque from treated areas. It’s proven to prevent and reduce gingivitis when used as directed.2

The Waterpik Sonic-Fusion toothbrush also has the ADA Seal of Acceptance. The association found the Waterpik toothbrush effectively removes plaque along the gum line and prevents or reduces gingivitis when used as directed.

How Does Waterpik Compare to String Floss? 

Waterpik Water Flossers are clinically proven to be an effective alternative to traditional string floss. 

One study claims the Waterpik Sonic-Fusion is up to 50% more effective at improving gum health than string floss. 4 However, many dental professionals still recommend string floss over water flossers because it’s more well-studied.

If regular flossing isn’t getting the results you’re looking for, a water flosser might be the best option for you. If you’re new to water flossing, your dentist can recommend whether a Waterpik is right for you.

Can I Use the Sonic-Fusion if I Have Dental Restorations?

The Sonic-Fusion is perfect for anyone with dental restorations or orthodontic devices, including:

  • Braces
  • Implants
  • Crowns
  • Bridges

The Sonic-Fusion Waterpik helps protect your investment in your dental work.

Restorations like implants, bridges, or crowns can be challenging to clean. The Waterpik flossing toothbrush is designed to clean around all types of dental work and restorations.

Unlike dental floss, the unique water-pulsating action helps clean under bridges and around crowns where bacteria and food can get trapped.

Pros and Cons of the Waterpik Sonic-Fusion

Using a Waterpik Sonic-Fusion offers many benefits, but there are also some downsides:


The pros of the Waterpik Sonic-Fusion include:

  • Easy to use
  • Cleans hard-to-reach areas
  • Cleans between tightly spaced teeth
  • Reduces inflammation
  • Reduces the risk of gingivitis
  • High and low brushing speeds
  • Quieter than other water flossers
  • Ideal for cleaning between orthodontic and restorative appliances

A Waterpik can help people who struggle with flossing hard-to-reach areas of the mouth, tightly spaced teeth, and periodontal pockets.

Waterpiks are easy to use. Some people may experience a learning curve while figuring out their most comfortable water temperature and power setting.


The cons of the Waterpik Sonic-Fusion include:

  • Water flossing isn’t portable (the brush must be connected to the base)
  • Unlike other water flossers, Sonic-Fusion doesn’t use multiple tips for a precise clean
  • Costs more than string floss

Can I Use Mouthwash in My Sonic-Fusion?

You can use most mouthwashes in the reservoir of your Sonic-Fusion. The exceptions are povidone-iodine and pure essential oil, such as tea tree oil, which can damage the device.

If you use any agent other than water in the reservoir, you should flush the unit with water immediately after use.

In addition to mouthwash, Waterpik toothbrush users can use any toothpaste type with the unit, including baking soda products.

How Much Does Waterpik Sonic-Fusion Cost?

The Waterpik Sonic-Fusion 2.0 ranges in price from $160 to $199.99. That may seem like a lot for a dental health device, but you get a sonic toothbrush and water flosser in one package.

What is the Waterpik Sonic Fusion 2.0 flossing toothbrush?

Waterpik’s Sonic-Fusion 2.0 is the company’s second-generation flossing toothbrush.

It combines the functions of an ultrasonic toothbrush and a water flosser into a single device. It’s made to be an easier and more practical way for you to look after your teeth and gums.

The Waterpik Sonic Fusion looks like other electric toothbrushes on the market today. The main distinction is that the handle and brush head also serve as the water flosser’s handle and nozzle. Rather than using a traditional water flosser nozzle, water is blasted through the brush head.

This review will go into great depth, but the promotional video below provides a decent summary of the product.

How to use the Waterpik Sonic Fusion toothbrush

To use the Sonic-Fusion 2. 0, there are a few important steps that are clearly illustrated in the video below.

If you wish to brush and floss your teeth individually, then follow these steps:

Step 1: Fill the water tank or reservoir halfway with lukewarm water.

Step 2: Connect or detach the hose from the toothbrush handle’s base.

Step 3: With the rotatable dial on the left of the device, you can adjust the pressure of the water flossing.

Step 4: Activate the brush button. Brush your teeth twice a day for 2 minutes. For instruction, use the built-in timer.

Step 5: Place the brush head in your mouth while leaning over the washbasin. Allow water to flow from the mouth into the washbowl while keeping the lips closed sufficiently to avoid splashing.

Step 6: Start flossing your teeth by pressing the floss button. Water should be aimed towards the gum line at a 90-degree angle. Follow the gumline and pause between teeth for a few moments. If necessary, adjust the pressure by twisting the dial.

Step 7: When finished, push the floss button again to turn off the device.

Waterpik Sonic Fusion 2.0 review

Watch the video review to understand the upsides and downsides of this product.

The reviewer in this video claims that he has been putting the Waterpik Sonic-Fusion to the test for a few weeks. He found advantages and disadvantages to using a flossing toothbrush combination.

Is the Waterpik Sonic-Fusion the best flossing toothbrush?

He thinks that Waterpik makes fantastic products and that the idea of a flossing toothbrush is an overall great idea. But he likes the Waterpik complete care system better, which includes a separate toothbrush and water flosser. Investing in a separate ultrasonic toothbrush and water flosser might be a better option than combining the two.

We must recognize that many people do not floss their teeth, even though flossing is an important part of cleaning your teeth and maintaining your dental health. Brushing your teeth with a manual or electric toothbrush might leave up to 40% of the tooth surfaces unbrushed.

That’s where flossing with string floss or interdental brushes comes in handy since it cleans in between the narrow areas between our teeth where plaque, germs, and other contaminants may accumulate and cause serious oral health problems.

Waterpik is well-known for its water flossers, which are a contemporary alternative to string floss or interdental brushes if you like something different. The Sonic Fusion technology has been clinically proven and is authorized by the American Dental Association, so it has a lot going for it, and the water flossing feature is very useful.

However, there are certain limitations when combining a water flosser with a toothbrush, which current water flosser users may find bothersome, and even new water flosser users may find somewhat uncomfortable.

That’s because the water is sprayed through the toothbrush head rather than through the more traditional water flosser tips. When the two are combined, you get a brushing and water flossing experience together, which he doesn’t recommend since it feels a little awkward.

From his perspective, the toothbrush itself performs well. It does a good job of cleaning teeth. It functions similarly to a typical sonic cleaner, such as the Phillips Sonicare electric toothbrush. It’s nice to hold it in your hand, although it feels a little hefty because it’s a detachable hose that feeds the water in while using the flosser.

Given the size, the battery life of just seven days is disappointing, especially considering that most electric toothbrushes now have two-week battery life.

The brushing experience is fine, but it lacks the premium feel of some electric toothbrushes with more rubber on the handles. It’s also beautifully made on the brush handle itself. Of course, the brush heads may be removed and replaced.

When the brush head is actually in use, it produces a very loud and uncomfortable noise. It is much louder in comparison to other sonic cleaners and has more of a high-pitched whiney sound. You might get used to it, but some people may not, according to some reviews we have read on Amazon or other websites.

Waterpik Sonic Fusion review

Because the power ranges from 100 to 240 volts, you won’t need a voltage converter if you travel with it; all you’ll need is a plug adapter.

When it comes to flossing your teeth, you fill the reservoir on the device. There are ten pressure settings available, which can be controlled by the dial on the side.

You have a couple of buttons to switch between brushing and flossing modes, and then you move the toothbrush around your mouth to direct it to the area of your mouth where you want to aim that water floss jet. This is when he found the brush head’s flaws.

When you’re attempting to get it between the teeth, it’s a lot bigger and a lot more difficult. One of the advantages of a classic water flosser is that it has separate jet tips, which gives you the feeling that you have better control.

Waterpik provides you with a 3-year warranty on the Sonic Fusion 2.0, which is something the company should be commended for.

Waterpik Sonic-Fusion flossing toothbrush replacement heads

The toothbrush has a built-in timer and pacer to assist you in brushing for the appropriate period. There’s only one style of brushing, and the toothbrush will turn off automatically at the end of a cleaning cycle.

There is a travel case included in the package that can hold the toothbrush and up to two brush heads, so you can take it with you when you travel. However, with seven-day battery life, you’ll be restricted to how long you can go without charging.

The issue is that the charger is also the base station, which is a little heavy to pack in your baggage while traveling. So, if you’re going away for a few weeks, you’ll almost certainly need to find an alternate option.

When compared to Oral B and other brands, the replacement brushes are more expensive. The Waterpik Sonic Fusion toothbrush replacement heads cost about $25 a piece, which is rather pricey. This increases the total cost of owning this sonic fusion flossing toothbrush. So that’s something to think about.

Waterpik Sonic Fusion reviews on Amazon

Very effective, pretty loud.

Surprisingly effective. Pretty loud, too. Version 2 is supposed to be quieter than the previous model. If that’s true then I’m glad I skipped that one! Regardless, it performs as advertised and is effective if being used as a toothbrush, a water flosser, or both in tandem.

It has a built-in timer for brushing, and I find myself brushing & flossing longer than I used to. At this time only brush heads are available. Would be better if different types of floss/brush heads were able to be used with it.


Somewhat complex to use.

The combination brush/floss function does not work. The pulsating water washes away the toothpaste instantly. Also, the curled hose isn’t long enough for comfortable use. Recommend buying the WaterPik floss only product and save some money. Brush by some other method.

A Little Difficult to Use

I like the idea of an all-in-one unit but the WaterPik feature is a bit hard to use. The cord doesn’t move very well and it’s awkward and water tends to get everywhere. In the end, having two separate units is probably better but for the cost and having the unit take up less counter space this is nice.

Waterpik Sonic-Fusion 2.0 vs version 1.0

In comparison to Waterpik Sonic Fusion version 1.0, there have been some improvements made with the newer version 2.0. These improvements in functionality and performance include these added features:

  • Reduced brushing noise
  • 2x bristle tip speed
  • 2 brushing speeds (high and low)
  • Better battery (lithium-ion)
  • Flossing power increased by 30%

Recommended alternatives to the Waterpik Sonic Fusion

Even though the Waterpik Sonic Fusion version 2. 0 has improved, we think you might be better off purchasing a water flosser and an electric toothbrush separately. You get the best of both worlds, and a water flosser with jet tips provides better functionality.

You can use a superior electric toothbrush with perhaps more high-end features, such as longer battery life and cheaper brush heads.

If you’re dedicated to the Waterpik brand and just want a water flosser, check out our Waterpik Aquarius WP-660 review on one of their most popular water flossers. You can also read about the cordless WP-560 range here.

As a better and cheaper alternative we recommend the cariPRO ultrasonic toothbrush combined with the cariPRO water flosser. That’s an excellent combination, and it’ll probably save you money over purchasing Waterpik Sonic Fusion 2.0 alone. It’s a pity you have to spend extra to merge two products into one that, in our opinion, doesn’t accomplish the job as well as two independent ones.


Combining a toothbrush and water flosser into one device is a great innovative idea. Brushing and flossing your teeth are two essential components of any effective oral hygiene practice. Flossing and brushing twice a day are recommended for everyone. 

The issue is that far too many people do not floss. Interdental brushes and string floss are uncomfortable, unpleasant, and time-consuming for many people. 

The Waterpik Sonic Fusion 2.0 seems to make the procedure a little easier. It is a product that blends two separate items into one. As a result, the chances of completing both activities and improving your overall dental hygiene are much better.

  • Only one device is needed for brushing teeth and water flossing

  • Attractive and stylish design

  • 10 different pressure settings to choose from

  • Recommended brushing time with timer and pacer

  • Approved by the American Dental Association (ADA)

  • 3-year warranty

  • Combines two devices into one – It’s a brilliant idea, but the execution is not that great and it lacks functionality and performance

  • The Waterpik Sonic Fusion flossing toothbrush has a short battery life

  • The water flosser isn’t easily transportable because the charging device is built-in with the reservoir

  • Expensive – there are cheaper alternatives.

The toothbrush works great, and so does the water flosser, to some extent. However, it has a few limitations since the water comes through the brush head and not through a jet tip, like with a traditional water flosser. The noise is quite loud, and the water flosser lacks functionality.

Compared to other electric toothbrushes on the market today, the battery life isn’t as impressive. And when you compare the pricing of the Waterpik Sonic Fusion 2.0 to other options on the market, you’ll see that it’s actually more costly than buying two separate devices.

Some of the issues with the first version have been taken into account in the 2.0. The battery life of the original Waterpik Sonic Fusion flossing toothbrush was poor, and the noise it produced was annoying. We’re happy to report that the noise has been reduced. The battery life is somewhat improved, but not as fantastic as the manufacturer claims.

Although the idea is fantastic, and some of the problems with version 1.0 have been addressed, we believe you would be better off purchasing an ultrasonic toothbrush and water flosser separately. For less money, you may acquire equal, if not greater, advantages.

You get the best of both, and the water flosser with jet tips provides better functionality. You may also choose a better ultrasonic toothbrush with perhaps more premium features, such as longer battery life and less expensive replacement brush heads.


Is the cariPRO better than the Waterpik Sonic-Fusion 2.0 flossing toothbrush?

The Waterpik Sonic-Fusion 2.0 is a great product, especially for those who are looking for a 2-in-1 solution. It comes with a lot of great features. However, there are also some disadvantages to having a combination unit.

The flosser might not have the same performance as a water flosser with jet tips. The battery life is not that good, and you might need another solution if you are planning to go on holiday for longer than a week. Another reason is the total cost. The Waterpik Sonic-Fusion 2.0 costs more than buying two separate devices with better performance and functionality.

That’s why we recommend the cariPRO ultrasonic toothbrush and the cariPRO water flosser.

Should you use a water flosser before or after brushing your teeth?

We suggest using the water flosser before brushing with an electric or ultrasonic toothbrush. Brushing and toothpaste are more effective when food and particles are gone.

Why do I need an irrigator and how is it different from a toothbrush – Dr.Bei

  • Why do I need an irrigator and how is it different from a toothbrush

Forget about bad breath, clean your braces, reduce bleeding gums, or just brush your teeth to a pleasant squeak – all this helps to make a irrigator. We understand what kind of device it is and in what cases it is useful.

What is the irrigator

The irrigator cleans the teeth with a pulsating jet of water. Due to the powerful pressure, it destroys plaque and removes food particles that the brush is not able to reach. At the same time, the device massages the gums – this helps with many diseases, and is simply useful for prevention.
At the same time, the irrigator cannot completely replace the toothbrush. They must be used in pairs.

There are three types of irrigators:

  • professional – used by dentists;
  • stationary – powerful irrigators for family use, they work from the outlet and usually take up a lot of space;
  • portable – they are compact, they are convenient to take on a trip or just use them every day.

For example, the miniature Dr.Bei GF3 Silver can be stored even in a small cabinet. A 30-minute charge is enough to use the device for 30 days.

The photo shows a portable irrigator DR.BEI GF3 Silver

How the irrigator works

All irrigators operate on the same principle. We explain using the example of the same GF3 Silver model.

  • You fill the tank with water and start the device. The powerful pump creates a thin stream 0.6 mm thick. Water is supplied in small pulses with a frequency of 1600 pulses per minute.
  • The jet should be directed along the gum line and between the teeth. The irrigator can remove plaque or massage the gums – the effect depends on the mode you choose.
  • One minute is enough for a complete cleaning.
  • With the help of additional attachments, you can clean your tongue or braces, as well as deal with especially stubborn dirt.

Why you need an irrigator

It helps clean your teeth better . The brush does not clean the interdental space well enough, and the irrigator does an excellent job of this task.

It fights bacteria, plaque and food debris, so eliminates bad breath in many cases.

Powerful water pressure removes plaque from the gum area .

Irrigator allows to gently clean orthodontic structures : braces, crowns and dental bridges.

Water massage is useful for certain gum diseases – for example, periodontal disease – or for the prevention of diseases.
