Waterpik Sonic Fusion

More Info

The Waterpik Sonic-Fusion Professional is a long-anticipated gamechanger: it’s the world’s first and only flossing toothbrush. Combining Waterpik’s highly-acclaimed water flossing technology with a sonic toothbrush, the Sonic-Fusion allows you to maintain a complete oral hygiene routine all from one compact device (view on Amazon).

After 10 years of innovation, the Sonic-Fusion initially became available in 2018. However, Waterpik voluntarily recalled early batches of the products to improve on safety concerns. Now, it is back on the shelves and is being welcomed with high praise.

In this article we will unpack everything you need to know about this one-of-a-kind device to help you decide whether it is right for you.


Clinical studies show that the Sonic-Fusion:

  • Is up to 2 times more effective than regular brushing and flossing
  • Removes up to 99.9% of plaque from treated areas
  • Is up to 50% more effective at improving gum health than string floss

How does the Waterpik Sonic-Fusion work?

The Waterpik Sonic-Fusion works in two parallel ways:

Firstly, as a Waterpik water flosser, removing plaque and debris with a pulsating stream of pressurised water.

Secondly, as a sonic toothbrush, cleaning teeth thoroughly with 30000 strokes per minute.

You can use these functions separately, or together for an all-in-one brushing and flossing experience.

5 Key Features of the Waterpik Sonic-Fusion Professional

1. 3 Cleaning Modes in 1 Device

Surveys show that as few as 4 out of 10 Americans floss daily and 20% don’t floss at all.

The excuse? Convenience.

By combining the brushing and flossing experience, Waterpik presents an oral hygiene routine as a whole. Even if our oral care routine isn’t perfect, most Americans at least brush their teeth twice a day. Now flossing can piggyback off that habit with as little effort as possible.

How does it work? The Sonic-Fusion has a unique toothbrush head that incorporates the flossing element inside the toothbrush (view details). Pressurised and pulsating water is ejected through the flossing tip to dislodge any food debris and bacteria build up. The Sonic-Fusion allows user to save time and space as they not only use the same device, but even the same head for both brushing and flossing.

However, there are a couple of drawbacks to this. Due to the unique design, other Waterpik flossing tips are not compatible with the Sonic-Fusion. This means that the tailored options such as tips for gingivitis or orthodontics are not available. While the Sonic-Fusion can be used for these conditions, you may not be able to get the optimum result as with a standard Waterpik.

2. Advanced Water Pressure Control System with 10 Settings

Like most of Waterpik’s countertop water flossers, the Sonic-Fusion comes with 10 different pressure settings. A variety of pressure settings can help you to tailor your flossing session to your needs.

New users should start on the lowest pressure setting before working up to the most comfortable setting for them.

3. 2 Minute Timer with 30 Second Pacer

Brushing your teeth for the recommended time of 2 minutes twice daily is one of the biggest ways to maintain good oral hygiene, yet the average for Americans comes in at just 1 minute 50 seconds.

Doesn’t sound like much? That’s 20 seconds less than recommended every day. Which is 5 minutes less every month or 2 hours less every year.

The best way to make sure you hit the 2 minute mark every session is to time your brushing. Of course, this can be done without brusher and pacer, but to ensure ease and consistency: integration is everything.

By incorporating a timer seamlessly into your routine, you can hit the recommended brushing time, every time. On top of that, the 30 second pacer helps to ensure that each section of the mouth is targeted evenly.

4. Global Voltage (100 – 240VAC, 50/60Hz)

The Waterpik Sonic-Fusion has global voltage which means you can use it anywhere across the globe. It comes with a small travel case and, if you’re really short of space, you can take the toothbrush separately.

5. Three-Year Warranty

Waterpik products have been a top choice for several decades because of their effectiveness and reliability.

There have been some complaints of the Waterpik channel getting clogged up and stopping working. Mostly, this is due to limescale build up in hard water areas and his problem is often avoided with regular maintenance as per the owner’s manual.

If you do find yourself with a faulty product, the Sonic-Fusion comes with a 3 year warranty.

Points to be aware of

Sonic not oscillating

The toothbrush head use sonic technology to clean teeth and does not have any oscillating capability (view details). Sonic technology is more than capable of cleaning thoroughly though, so while you may have a preference in feel, the cleaning power is much the same.

If you have never used a sonic toothbrush before, you may feel a tingling or tickling sensation initially.

Small head

Currently, there is only one brush head available for the Sonic-Fusion. This is a relatively small, circular head. Small toothbrush heads allow the maximum manoeuvrability, allowing you to access hard to reach areas. However, if you do favour a larger toothbrush head then be aware of the current lack of options.

  • Gentle cleaning - the soft bristles remove plaque from teeth while also being gentle on gums

Streamlined features

If you have an oral hygiene routine that already incorporates advanced features, then this may not be the device for you.

The toothbrush is a solid sonic toothbrush but doesn’t go much beyond that. For example, it lacks whitening or gum specific modes that can be found with products such as Sonicare and Oral B. For those really into their gadgets, there is also no capability of Bluetooth connectivity.

The water flossing side tells a similar story. The basic functions that you would want in a water flosser are there, but massage mode (for gum health) and specialist tips are not currently available for use with the Sonic-Fusion.

So what’s the bottom line?

Waterpik Sonic-Fusion Professional Flossing Toothbrush, Electric Toothbrush and Water Flosser in One...

The Sonic-Fusion is an innovative move by Waterpik and can be a useful in helping to improve oral hygiene routines across the globe.

If you are in the minority and already look after your teeth perfectly with a refined and consistent oral care routine, this may not be the product for you as it lacks some features and specialised options of standalone devices.

That said, the majority of Americans miss the mark when it comes to oral care — often in more ways than one! For those pressed for time and those who find it difficult to keep up the consistency of brushing and flossing each day as recommended, this could be a game-changer.

Can you order an additional toothbrush?

Additional toothbrush handles are not available for purchase. However, color-coded toothbrush heads mean that each member of the family can use their own toothbrush head with the device.

Can you add mouthwash to the reservoir?

Yes, you can add a small amount of mouthwash to the water for an extra fresh feel.

No. The toothbrush only has a timer.

How long is the power cord?

The power cord can be safely extended to 48 inches.

Can I use a Sonic-Fusion toothbrush head on my old Waterpik?
