How Does the Waterpik Sonic-Fusion Work?

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

With the Waterpik Sonic Fusion toothbrush, users can floss their teeth while they brush. The brushing and flossing combo included in the Waterpik toothbrush helps users achieve superior oral care results while eliminating the hassle of managing multiple dental cleaning devices. 

The Waterpik Sonic-Fusion turns oral hygiene into a one-step process that's twice as effective as regular brushing and flossing by: 

  • Eliminating more plaque
  • Reducing gingival (gum) bleeding and gingival inflammation
  • Effectively cleaning hard-to-reach areas (that cannot be cleaned with a regular toothbrush)

The Sonic-Fusion Waterpik toothbrush head has a built-in water flosser tip that pulsates from the brush head’s center. 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.

This flossing toothbrush also comes with a 2-minute brushing timer and: 

  • Two brush heads
  • A 30-second pacer
  • An advanced pressure control
  • A recharge indicator light 
  • An instruction manual
  • A deluxe toothbrush travel case 

Users can purchase additional Waterpik Sonic-Fusion compact 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 flossing toothbrush.

Additional Features of Waterpik Sonic-Fusion

  • Brush head and handle The Sonic-Fusion comes with an easy-to-grip, lightweight, balanced handle that holds the mode buttons easy to activate. This handle can also easily convert to a power brush for travel.
  • Irrigation hose — The irrigation hose delivers the irrigant 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 compact 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 so users can customize the Sonic-Fusion toothbrush to their needs quickly.

How Effective is the Sonic-Fusion Waterpik?

A clinical study 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. Thus, the device is considerably more effective than Sonicare® DiamondClean for improving oral 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, or 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 the bridge and around crowns where bacteria and food can get trapped.

You should speak with your dentist if you have a dental restoration to avoid causing any damage or trauma. 

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. They can also help individuals who cannot keep up with regular oral hygiene by keeping their breath fresher for a longer period.

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 Waterpiks may not be enough to eradicate 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. These results are why Waterpik is a water flossing tool of choice among many dental hygienists. 

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.
