Maintaining impeccable oral hygiene can often feel like a constant battle, especially when traditional string floss struggles to reach every nook and cranny. Many of us grapple with the discomfort or inefficiency of conventional flossing methods, leading to less-than-optimal results. This is where a dedicated oral care device like the Waterpik Aquarius WP-660 Water Flosser steps in, offering a remarkably effective and user-friendly solution for a healthier mouth. Designed to elevate your daily routine, this advanced countertop water flosser promises to transform your dental health. This comprehensive guide will explore the Waterpik Aquarius WP-660, covering its standout features, how it compares to similar models, proper usage techniques, and the profound benefits it brings to your oral care regimen.

What is a Water Flosser and Why Choose the Waterpik Aquarius WP-660?
A water flosser, also known as an oral irrigator, is a dental device that uses a stream of pulsating water to remove plaque, food debris, and bacteria from between teeth and below the gumline. Unlike string floss, which relies on manual dexterity and can sometimes be harsh on gums, water flossers provide a gentle yet powerful clean. The Waterpik Aquarius WP-660, in particular, leverages pulse-modulation technology to deliver highly effective cleaning, making it a professional-grade choice for home use.
Choosing a water flosser like the WP-660 offers several distinct advantages over traditional string floss. It is clinically proven to be significantly more effective at improving gum health and removing up to 99.9% of plaque from treated areas. This superior performance is largely due to its ability to reach areas that string floss often misses, such as deep gum pockets and around dental work. For those seeking a more convenient, thorough, and less abrasive method for interdental cleaning, the Waterpik Aquarius WP-660 stands out as an ADA (American Dental Association) accepted product, validating its safety and effectiveness.
Key Features and Design of the Waterpik Aquarius WP-660
The Waterpik Aquarius WP-660 is engineered with an array of features designed to provide a customized and highly effective flossing experience. Its advanced design combines power with user-centric functionality, making it a popular choice among dental professionals and users alike.
At its core, the WP-660 incorporates sophisticated technology for superior cleaning. It features two distinct modes: the Floss Mode, which utilizes pulse-modulation technology for maximum plaque removal, and the Hydro-Pulse Massage Mode, specifically designed to stimulate gum circulation for enhanced gum health. With 10 pressure settings, ranging from a gentle 10 PSI to a powerful 100 PSI, you have complete control to tailor the intensity to your comfort level and specific oral needs. This versatility is crucial for both new users starting with sensitive gums and experienced users requiring a robust clean.
The device boasts a large, removable water reservoir with a capacity of 22 ounces (651ml), providing enough water for over 90 seconds of continuous flossing. This generous capacity means you can complete a thorough cleaning session without needing to refill, a significant advantage over smaller, cordless models. The reservoir is also easy to fill and clean.
The Waterpik Aquarius WP-660 comes equipped with 7 flossing tips to cater to various dental requirements. These include:
- Classic Jet Tips: For general use, three are typically included.
- Orthodontic Tip: Designed to clean around braces and wires.
- Plaque Seeker™ Tip: Ideal for implants, crowns, bridges, and veneers.
- Pik Pocket™ Tip: A soft-tipped tool for periodontal pockets.
- Toothbrush Tip: Combines brushing and water flossing (though some WP-660 packages may include 4 classic tips instead of a toothbrush tip; check specific product details for exact inclusions).
User-friendliness is central to the WP-660’s design. It includes a 360-degree rotating tip handle that allows you to easily reach all areas of your mouth, including back teeth. An on/off slider switch conveniently located on the handle lets you control water flow without reaching for the main unit. To ensure thorough cleaning, a 1-minute timer with a 30-second pacer guides you to floss each quadrant of your mouth for the recommended duration. Its compact footprint and sleek design ensure it fits comfortably on most bathroom countertops, though it does require being plugged into a 120VAC/60Hz outlet for operation. While Waterpik labels it “ultra quiet,” some users note a moderate noise level, typically around 72 decibels, which is generally not disruptive. The unit is also backed by a comprehensive 3-year limited warranty, providing peace of mind.
A Comparative Look: Waterpik Aquarius WP-660 vs. WP-670 (Professional)
When considering a Waterpik Aquarius model, you might encounter both the WP-660 and the WP-670, often referred to as the Aquarius Professional or Designer Series. It’s important to understand that, fundamentally, these two countertop water flossers deliver the same core cleaning performance. Both models utilize the same pulse-modulation technology, offer 10 pressure settings, and provide the beneficial Hydro-Pulse Massage Mode.
The primary distinctions lie in aesthetics and specific accessory inclusions. The WP-670 typically features chrome-colored accents on elements like the control wheel and power button, giving it a slightly more premium or “designer” look. It also offers a wider range of color options beyond the classic white of the WP-660. While both come with 7 tips, there can be a slight variation in the types of tips included. For instance, the WP-670 often includes a toothbrush tip and a tip storage case, whereas the WP-660 usually includes an additional classic jet tip instead of a toothbrush tip.
In terms of pricing, the WP-670 generally carries a slightly higher retail price due to these cosmetic enhancements and the potential inclusion of a tip storage case. For users prioritizing core performance and value, the WP-660 offers an identical flossing experience at a slightly more affordable price point. If aesthetic details and a wider color selection are important to you, the WP-670 might be appealing, but the WP-660 remains the top choice for pure functionality and proven oral health benefits.
How to Effectively Use Your Waterpik Aquarius WP-660
To maximize the benefits of your Waterpik Aquarius WP-660, proper technique is key. Integrating it seamlessly into your daily routine can significantly enhance your oral hygiene.
Preparation before use:
- Fill the Reservoir: Remove the reservoir from the base, fill it with lukewarm water. You can also add a small amount of mouthwash if desired. Place it back on the base.
- Select a Tip: Choose the appropriate flossing tip for your needs and firmly insert it into the handle until it clicks.
- Adjust Pressure: For first-time users, start with the lowest pressure setting (level 1). Gradually increase the pressure over several days or weeks as your gums become accustomed to the water stream. Aim for a comfortable yet effective pressure level, often around 7 for experienced users.
Steps for effective flossing:
- Lean Over the Sink: Lean over the sink and place the tip in your mouth. Keep your lips slightly apart to allow the water to drain into the sink and avoid splashing, but close enough to prevent excessive spray.
- Turn On the Unit: Turn on the water flosser, then slide the on/off switch on the handle to activate the water stream.
- Guide the Tip: Direct the water stream at a 90-degree angle to your gumline. Work your way around your mouth, pausing briefly between teeth and along the gumline.
- Follow the Pacer: The built-in 1-minute timer with a 30-second pacer will alert you to move to a different quadrant of your mouth, ensuring you clean all areas thoroughly.
- Clean All Surfaces: Ensure you trace both the front and back surfaces of your teeth, paying special attention to areas around dental work, braces, or crowded teeth.
Maintenance and Best Practices:
- Daily Use: For optimal results, use your Waterpik Aquarius WP-660 at least once a day, preferably after brushing.
- Empty and Dry: After each use, empty any remaining water from the reservoir to prevent bacterial growth and leave it open to air dry.
- Regular Cleaning: Periodically clean the reservoir and the unit according to the manufacturer’s instructions, typically with warm, soapy water or a descaling solution.
- Tip Replacement: Replace flossing tips every 3-6 months, or more frequently if they show signs of wear.
The Transformative Benefits of Water Flossing with WP-660
Incorporating the Waterpik Aquarius WP-660 into your daily routine offers a wealth of benefits that extend far beyond what traditional brushing and string flossing can achieve. It’s a proactive step towards comprehensive oral health.
One of the most significant advantages is its superior plaque and bacteria removal. The pulsating water stream effectively dislodges food particles and plaque from interdental spaces and beneath the gumline, areas often missed by brushing alone. This deep cleaning is crucial for preventing the buildup of harmful bacteria that lead to dental issues. Dr. Kumar T Vadivel, a board-certified periodontist, highly recommends water flossers, stating they “remove the plaque in between the teeth more effectively than anything else.”
The WP-660 is clinically proven to improve gum health by reducing gingivitis and gum inflammation. The Hydro-Pulse Massage Mode specifically stimulates gum tissue, enhancing circulation and promoting stronger, healthier gums. Users frequently report a noticeable reduction in gum bleeding and a fresher feeling mouth after consistent use.

For individuals with specific dental needs, the Waterpik Aquarius WP-660 is a game-changer. It’s particularly beneficial for those with braces, as the specialized orthodontic tip can navigate around wires and brackets to remove trapped food and plaque more efficiently than string floss. People with implants, crowns, bridges, and veneers also find immense value in the Plaque Seeker™ tip, which effectively cleans around these restorations. Moreover, the Pik Pocket™ tip offers a gentle yet effective way to clean periodontal pockets for those managing gum disease. Beyond these specific applications, the thorough cleaning action also contributes to overall oral freshness by eliminating odor-causing bacteria, combating bad breath.
Important Considerations for Water Flosser Users
While the Waterpik Aquarius WP-660 is an invaluable tool for oral hygiene, it’s crucial to understand its role within a complete dental care regimen.
Firstly, a water flosser is designed to complement, not replace, traditional brushing. It effectively cleans between teeth and below the gumline, but brushing remains essential for cleaning tooth surfaces and removing plaque from the enamel. Always brush your teeth at least twice a day with a fluoride toothpaste.
Secondly, always start with the lowest pressure setting and gradually increase it as your gums adapt. Using too high a pressure setting initially can cause gum sensitivity or bleeding. If you experience persistent discomfort or gum bleeding, or have any pre-existing dental conditions, it is always best to consult your dentist or periodontist. They can provide personalized advice on the optimal usage and pressure settings for your unique oral health needs.
Lastly, new users might find there’s a slight learning curve with water flossers. It’s common to experience some splashing initially. Leaning over the sink and keeping your mouth partially closed while the water drains can help mitigate this. With a little practice, using the Waterpik Aquarius WP-660 will become a seamless part of your daily routine.
