What is Waterpik Sonic-Fusion?

Waterpik Sonic Fusion 2.0

The Waterpik Sonic-Fusion 2.0 is the second version of the world's first flossing toothbrush. The Sonic-Fusion 2.0 combines the power of an advanced sonic toothbrush with Waterpik Water Flossers’ proven effectiveness.

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 users 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 gum bleeding inflammation
  • Cleaning hard-to-reach areas (that a regular toothbrush can't reach)

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.

The toothbrush also has various cleaning modes and pressure settings. This feature offers each user the ability to customize their water pressure control based on their preferences.

Other features include: 

  • Two brush heads
  • 2-minute timer
  • 30-second pacer
  • Advanced pressure control
  • Recharge indicator light 
  • Deluxe toothbrush travel case 

Users can purchase replacement flossing brush heads separately. 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.

Additional Features of Waterpik Sonic-Fusion

The additional features of the Waterpik Sonic-Fusion include:

Brush head and handle

The Sonic-Fusion 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 is lightweight and stable so that 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.

How Effective is the Sonic-Fusion Waterpik 2.0?

A clinical study (by Waterpik) found that the Waterpik Sonic-Fusion flossing toothbrush is twice as effective as traditional brushing and flossing to reduce plaque and improve gum health.

Compared with a traditional electric toothbrush, the Sonicare DiamondClean, the Waterpik Sonic-Fusion toothbrush was significantly more effective for removing plaque and improving gingival health.

The Sonic-Fusion Waterpik offers up to 99.9% of plaque removal from treated areas and is proven to prevent and reduce gingivitis when used as directed.

The Waterpik Sonic-Fusion toothbrush has an ADA Seal of Approval from the American Dental Association. The association found that the Waterpik toothbrush is safe and effective for removing plaque along the gum line and preventing or reducing gingivitis when used as directed.

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
  • Periodontal pockets

The Sonic-Fusion Waterpik helps to protect the investment you have made in your dental work.

Dental work 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 Waterpik Water Flossers


The pros of Waterpik Water Flossers include:

  • Easy to use
  • Cleans hard-to-reach areas
  • Cleans between tightly spaced teeth
  • Reduces inflammation
  • Reduces the risk of gingivitis
  • Ideal for cleaning between orthodontic and restorative appliances

Using a Waterpik can help individuals 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 Waterpik Water Flossers include:

  • May not remove all plaque
  • Can be costly
  • Messy

A Waterpik may not be enough to eliminate plaque from the surface of teeth. Some people like to use string floss first to scrape off and loosen plaque, and then use a Waterpik to rinse out residue and plaque left behind.

While Waterpiks are safe to use and contain no risk, they are more expensive than traditional string floss.

Can I Use Mouthwash in My Sonic-Fusion?

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

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 Does Waterpik Compare to String Floss? 

The Waterpik is an alternative solution to traditional dental string floss for removing plaque. However, you should confirm with your dentist that you are using it correctly and don’t need to use traditional string floss. 

Waterpik Water Flossers are the only brand clinically proven to be an effective alternative to traditional floss to remove plaque biofilm and reduce gum bleeding and inflammation. Studies show that the Waterpik Sonic-Fusion is up to 50% more effective at improving gum health than string floss.

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

How Much Does Waterpik Sonic-Fusion Cost?

The Waterpik Sonic-Fusion 2.0 ranges in price from $140 to $199.99.

This Waterpik Water Flosser kit allows you to brush and floss your teeth without switching products. The kit includes one patented water flossing brush head, a premium toothbrush case, and global voltage. It is clinically proven to be twice as effective as traditional brushing and flossing in improving gum health and removing plaque.

It features three different cleaning modes (brush, floss, and brush + floss) and a two-minute brushing timer with a 30-second pacer.
