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.

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 the Sonic-Fusion if I Have Dental Restorations?

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

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.

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.
