Best Electric Toothbrush With Water Flosser Combo (2026)
The Waterpik Sonic-Fusion 2.0 is our top pick for a combined electric toothbrush and water flosser. It uniquely integrates water flossing directly into the brush head, allowing you to brush and floss simultaneously. For those who prefer separate units in one package, the Waterpik Complete Care 9.5 pairs a premium water flosser with an oscillating toothbrush at a better value than buying them individually.
Combining an electric toothbrush with a water flosser creates the most comprehensive at-home oral care routine possible. While brushing cleans the broad surfaces of your teeth, water flossing reaches the tight spaces between teeth and below the gumline where bristles cannot penetrate. Having both devices in a single unit or combo package saves counter space, reduces clutter, and often costs less than purchasing each device separately.
There are two main types of combo units on the market. Integrated combos like the Waterpik Sonic-Fusion build water flossing capability directly into the toothbrush handle, allowing simultaneous brushing and flossing. Bundled combos pair a standalone electric toothbrush with a countertop or cordless water flosser in the same package, sharing a charging base or storage unit. Each approach has distinct advantages depending on your preferences and bathroom setup.

The Science Behind Combining Brushing and Water Flossing
Clinical research strongly supports the combination of electric brushing and water flossing as the gold standard for at-home oral care. A study published in the Journal of Clinical Dentistry found that the combination of a sonic toothbrush and water flosser removed 74% more plaque than a manual toothbrush and string floss combined. Another study showed that this combination reduced bleeding on probing by 26% more than traditional brushing and flossing after just four weeks.
The reason this combination works so well is that each technology targets different aspects of plaque and debris removal. Electric toothbrush bristles excel at removing plaque from the broad, accessible surfaces of teeth. Water flossers use a pulsating stream of water at pressures between 10 and 100 PSI to flush debris from the interproximal spaces between teeth and from periodontal pockets below the gumline, areas that bristles simply cannot reach effectively.
Integrated vs. Bundled: Which Is Better?
Integrated combos like the Waterpik Sonic-Fusion offer the convenience of doing both tasks simultaneously, which saves time and simplifies the routine. The water flows through channels in the brush head while you brush, flushing debris from between teeth as the bristles clean the surfaces. This is particularly appealing for people who find flossing tedious or who tend to skip it when short on time.
However, bundled combos with separate brush and flosser units give you more flexibility and generally better individual performance. A dedicated electric toothbrush like the Oral-B or Sonicare focuses entirely on brushing quality, while a standalone Waterpik flosser provides more powerful and targeted water flossing. The trade-off is slightly more counter space and a two-step routine rather than simultaneous cleaning.
For people with braces, implants, or periodontal disease, a bundled combo with a full-size water flosser is typically the better choice. These conditions require more thorough, targeted water flossing that benefits from the higher pressure settings and specialized tips available with standalone flosser units.
How to Use a Toothbrush and Water Flosser Combo
For best results, water floss before brushing. Start by filling the reservoir with warm water and selecting a comfortable pressure setting. Begin at the lowest setting if you are new to water flossing and gradually increase over the first week. Direct the water stream along the gumline, pausing briefly between each tooth to flush the interproximal space.
After water flossing, brush for the full 2-minute cycle using your preferred cleaning mode. The initial water flossing loosens and removes large debris particles, allowing the toothbrush bristles to make better contact with tooth surfaces and the fluoride in your toothpaste to penetrate more effectively into clean enamel.
Our Verdict
For the most convenient all-in-one experience, the Waterpik Sonic-Fusion 2.0 is unmatched. For the best overall cleaning performance, we recommend a DIY bundle pairing a premium electric toothbrush (like the Sonicare 4100 or Oral-B iO Series 5) with a dedicated Waterpik flosser. The Waterpik Complete Care 9.5 offers the best middle ground, providing solid performance in both brushing and flossing at a competitive price.
Frequently Asked Questions
Are electric toothbrush and water flosser combos worth it? +
Yes, combo units offer excellent value by combining two essential oral care devices at a lower price than buying them separately. They also save counter space. The Waterpik Sonic-Fusion and Complete Care lines are clinically proven to be more effective than brushing and traditional string flossing alone.
Should I brush or water floss first? +
Research published in the Journal of Clinical Dentistry suggests water flossing before brushing is more effective for reducing plaque. Water flossing first loosens debris between teeth and along the gumline, then brushing sweeps it away and allows fluoride in toothpaste better access to all tooth surfaces.
Can a water flosser replace regular flossing? +
The ADA accepts water flossers as an effective alternative to string floss. Clinical studies show water flossers can be up to 50% more effective than string floss for reducing gingivitis and up to 29% more effective for plaque removal. They are especially beneficial for people with braces, bridges, or implants who find string flossing difficult.
