Waterpik Sonic-Fusion Replacement Brush Heads — 2 Count Full-Size White/Chrome, Integrated Flossing & Soft High-Low Bristles

These are genuine Waterpik full-size Sonic-Fusion replacement brush heads (2-count) with integrated flossing technology for brushing and flossing in one brush.

If you use a Waterpik Sonic-Fusion or Sonic-Fusion Professional flossing toothbrush, these replacement heads restore optimal brushing performance and the built-in flossing channel designed for combined brushing and water-flossing action. Each pack contains two full-size heads — one with a white color ring and one with a chrome ring — plus protective covers and easy-open packaging. The heads are 25% larger than Waterpik’s compact options and feature soft high-low bristles engineered to clean tooth surfaces while the Sonic-Fusion device directs pressurized water between teeth.

How do these replacement heads fit and when should I change them?

These brush heads are engineered for compatibility with all Waterpik Sonic-Fusion and Sonic-Fusion Professional flossing toothbrush handles. They snap on and off the brush stem for quick swaps. Waterpik recommends replacing brush heads about every three months or sooner if bristles show wear.

• Compatible with Sonic-Fusion and Sonic-Fusion Professional models
• Simple snap-on attachment for fast replacement
• Replace every ~3 months or when bristles fray
• Includes two heads so you can alternate or share between users

What makes the full-size brush head different from compact options?

Full-size Sonic-Fusion heads are approximately 25% larger than Waterpik’s compact heads, offering more surface coverage per stroke. The larger profile is suited to users who prefer fuller coverage and slightly longer bristles for a comfortable brushing feel.

• 25% larger brush surface than compact heads
• Soft high-low bristles for gentle yet effective contact
• Designed to pair with the flossing water flow for combined cleaning

How does the built-in flossing technology work with brushing?

A patented flossing channel is integrated into each brush head, allowing the Sonic-Fusion handle to deliver pressurized water between teeth while you brush. The bristle pattern removes plaque from surfaces while the water removes debris from interdental spaces and along the gumline, combining two steps into one routine.

• Patented channel allows water to flow through the head during brushing
• High-low bristle pattern targets surface plaque while water flushes between teeth
• Two heads included for rotation or multi-user convenience

What comes in the package and how are the heads organized?

This two-count package includes two full-size replacement brush heads, each with its own protective cover and color-coded rings for user identification. Packaging is designed for easy opening and storage between uses.

• 2 full-size Sonic-Fusion replacement brush heads (white with white ring, white with chrome ring)
• 2 protective brush head covers included
• Color rings help separate users or assign heads by purpose
• Easy-open retail packaging

Who is this for: These replacement heads suit Sonic-Fusion toothbrush owners who prefer a larger brush head and want to keep using the two-in-one brushing and water-flossing system. They are ideal for households with two users who share a handle, people who like extra coverage per stroke, and anyone maintaining a regular three-month head-replacement schedule.
