Flossing is the step in our dental routine we are most likely to skip, yet it is crucial for preventing gum disease and decay. For many Singaporeans, the traditional string floss can be fiddly and uncomfortable. Enter the water flosser—a device that uses a pressurised stream of water to dislodge food and plaque from between teeth.
Whether you are battling to keep your braces clean, have dental implants, or simply want a fresher feeling than brushing alone can provide, a water flosser (or oral irrigator) is a worthy investment for your bathroom. We have curated a list of the top models available in Singapore, ranging from trusted global giants to popular local favourites.
Waterpik Aquarius Professional Water Flosser Designer Series, White, WP-670
Best Overall Countertop: Waterpik Aquarius Professional
Price: $220.50
The Waterpik Aquarius (often model WP-660) is widely regarded as the best water flosser on the market. As a countertop model, it requires a power socket (ensure you buy a unit with a Singapore Type G plug or use an adapter). It offers 10 pressure settings, making it versatile enough for sensitive gums and powerful deep cleaning alike. It features a massage mode for gum stimulation and a timer to ensure you don’t rush the job.
Why buy? It has a large water reservoir, meaning you won’t need to refill halfway through flossing.
Best Local Singaporean Brand: Zenyum Water Flosser Pro
Price: $149.90
Zenyum is a Singapore-founded success story, and their Water Flosser Pro is a hit locally. It is designed for the modern Singaporean bathroom: sleek, cordless, and aesthetically pleasing. It features a high-pulse water jet to remove plaque effectively and comes with an OLED display.
Why buy? It uses USB-C charging (very convenient), has a 30-day battery life, and being a local brand, support and warranty claims are straightforward.
Waterpik Cordless Advanced 2.0 Water Flosser
Best Premium Cordless: Waterpik Cordless Advanced
Price: $112.64
If you want the reliability of a Waterpik but lack the counter space for the Aquarius, the Cordless Advanced is the top choice. It is waterproof, meaning you can use it in the shower to minimise mess. It features a rapid magnetic charging system and is exceptionally quiet for a water flosser.
Why buy? It is perfect for the frequent traveller who refuses to compromise on dental health. The fit and finish are premium, and the grip is ergonomic.
Xiaomi Mijia Portable Water Flosser
Best Budget Choice: Xiaomi Mijia Portable Water Flosser
Price: $39.90
For those unsure about spending over $100 on a device, the Xiaomi Mijia flosser is an excellent entry point. Widely available on platforms like Shopee and Lazada, it offers surprising power and a decent battery life for a fraction of the price of premium brands. It usually comes with multiple nozzles, including one for tongue cleaning.
Why buy? It delivers strong water pressure and decent build quality, making it the undisputed king of budget dental care gadgets.
Philips Sonicare Cordless Power Flosser 3000, White, HX3826/21
Best for Quiet Operation: Philips Sonicare Power Flosser 3000
Price: $99.60
Philips uses “Quad Stream” technology, which creates an X-shaped stream of water. This covers more surface area and makes it easier to clean between teeth without needing perfect aim. It is significantly quieter than most Waterpik models, which is a blessing if you have thin walls or share a bathroom.
Why buy? The “Pulse Wave” technology guides you from tooth to tooth, ensuring you don’t miss spots, which is excellent for beginners.
Panasonic EW-DJ11-A503 Dental Flosser
Best for Travel: Panasonic EW-DJ11
Price: $69.07
Panasonic has a strong legacy in oral hygiene. This model is unique because of its collapsible design; the nozzle stores inside the unit, and the reservoir slides down, reducing it to the size of a small torch. It fits easily into any toiletries bag.
Why buy? It is the ultimate space-saver. While the water tank is smaller, the portability is unmatched for holidays or business trips.
Oral-B Aquacare 6 Pro-Expert
Best for Sensitive Gums: Oral-B Aquacare 6 Pro-Expert
Price: $139.90
Oral-B’s unique selling point is its Oxyjet technology, which enriches the water with micro-bubbles of air. This is designed to kill anaerobic bacteria and provide a very gentle cleaning experience. It is less “aggressive” than some other brands, making it ideal if you suffer from bleeding or sensitive gums.
Why buy? The “On-Demand” mode allows you to release water only when you press the button, giving you complete control and preventing water from spraying everywhere while you manoeuvre the device.
h2ofloss Dental Oral Irrigator
Best Value High-Capacity: H2ofloss Cordless Oral Irrigator
Price: $46.85 (UP $110) | 57% OFF
Another favourite on Singapore’s e-commerce sites, H2ofloss offers a slightly bulkier handheld unit, but with a distinct advantage: a massive 300ml tank (larger than most cordless models) and a “gravity ball” on the intake tube. This allows you to use the flosser at any angle—even upside down—without the water flow stopping.
Why buy? It offers high capacity and functionality at a very competitive price point, often undercutting major brands while providing similar pressure levels.

Frequently Asked Questions
Before you make a purchase, it is helpful to understand how these devices fit into your daily routine.
Do you water floss before or after brushing?
There is some debate, but most dental professionals recommend water flossing before brushing. This dislodges food particles and plaque, allowing your toothpaste’s fluoride to coat the spaces between your teeth more effectively when you brush afterwards. However, if you prefer the feeling of flushing out debris after brushing, that is acceptable too—consistency is key.
Do water flossers remove tartar?
No. Water flossers are excellent at removing soft plaque and food debris, but once plaque hardens into tartar (calculus), it cannot be removed at home. You will need a professional scale and polish at the dentist to remove tartar.
Which is better: a water flosser or thread floss?
Traditional string floss is generally considered the “gold standard” for scraping sticky plaque off the side of a tooth. However, a water flosser is often better for compliance (people actually use it), and it is superior for cleaning around braces, bridges, and implants where string snaps or gets stuck. For the best oral hygiene, using both is ideal.
What water flossers do dentists recommend? Dentists typically recommend brands that have the ADA (American Dental Association) Seal of Acceptance. Waterpik is the most widely recommended brand due to its extensive clinical studies. Philips Sonicare and Oral-B are also frequently recommended for their reliability and technology.
What are the advantages and disadvantages of water flossers?
Advantages of a water flosser include - easier to manoeuvre than string, excellent for gum health, massages gums, cleans periodontal pockets, and ideal for braces/implants.
Disadvantages of a water flosser include - can be messy (water spray), takes up counter space, requires charging or a power socket (check for a Singapore 3-pin plug compatibility), and costlier than floss.
Is it bad to use a water flosser every day? Not at all. It is highly recommended to use it once a day. It is a gentle way to maintain gum health without the risk of cutting your gums, which can happen with aggressive string flossing.
