Squeaky Clean Gums

High & Low Pressure Settings

High pressure setting provides a strong and forceful water stream that is useful for removing plaque and debris from deep in between the teeth and gums.

Low pressure setting provides a gentle water stream that is ideal for individuals with sensitive gums, braces, or other dental appliances. This setting is also recommended for individuals who are just starting to use a water flosser or for those who prefer a gentler cleaning experience.

Everything You Need in One Box

A comprehensive oral care package with all essential tools for effective water flossing in one convenient box. From the sleek water flosser unit itself to a variety of specialized nozzle tips, each component is designed to provide a thorough and gentle cleaning experience.

Thoroughly cleans plaque around braces and brackets

An effective tool for cleaning plaque and food particles around difficult-to-reach gum areas. Use Orthodontic Nozzle 103 for clearing braces and dental brackets and Subgingival Nozzle 102 to clean difficult areas. 

Dual Water Source System

Not all water flossers have dual water source system which makes W100 uniquely different. Dual water source system provides unlimited water capacity. A convenient feature for those who use a water flosser frequently, as it eliminates the need to continuously refill the water reservoir, which can be time-consuming and disruptive. 

Start your day right with better oral hygiene. Regular flossing and brushing can keep gum disease away.

Keep Your Smile Bright

Practice good oral hygiene to keep your mouth clean and disease-free

Get rid of food particles and prevent the buildup of plaque

Although flossing does not whiten your teeth, it keeps your teeth white by preventing plaque build-up, which may result in tooth decay or yellowing.

Prevention is easier than cure

Preventing gum disease from worsening in its early stages. If it is successfully treated in the early stages, it will not have lasting impact on oral health. 

How to Water Floss

1. Fill the reservoir with clean water.

2. Select the appropriate pressure setting. You may test the pressure settings before use.

3. Hold the tip of the nozzle perpendicular to the gumline.

4. Trace each tooth along the gumline for 3 seconds per tooth. When traced properly, it will cause a syphoning effect to pull the plaque and bacteria out.

5. Selecting the appropriate nozzle tip allows you to clean appliances such as metal braces which can be difficult to see and clean.

6. Position the nozzle on targeted areas you would like to remove such as stubborn plaque built-up or food deposits.

How do I use the water flosser without getting wet?

To prevent yourself from getting wet, here are some tips:

1. Ensure your mouth is closed, slightly ajar when flossing to allow the water to run out into the basin.

2. Lean forward over the basin.

Can I water floss my teeth everyday?

Yes, you can water floss your gumline as often as you like. It helps to improve your oral hygiene. 

Can the water flosser get wet?

Yes, the water flosser rating is IPX5. It can resist a sustained, low-pressure water jet spray. But it cannot be place into water. Out of abundance of precaution, keep the charging port dry before charging.

Should I floss before or after brushing?

Before brushing. Toothpaste contains fluoride, which is good for your oral health. Using the water floss before brushing your teeth prevents you from washing away the fluoride from your toothpaste.

How to use the 3 different nozzles?

Standard Nozzle W101
The nozzle for general use. 

Subgingival Nozzle 102
The nozzle to clean difficult areas. 

Orthodontic Nozzle 103

Can this water flosser be used to replace manual flossing? Like string flossing?

This water flossing cannot replace manual flossing. Compliment wet floss with manual flossing to your brushing routine to keep your gums optimally clean and healthy.

Can this water flosser be replaced with a toothbrush?

No. A water flosser is for water flossing between the teeth and around the gum line. It does not clean the surface of the teeth.

I have sensitive teeth. Can I do water flossing with W100?

Yes, you can do water flossing with W100. However, if you are new to water flossing, we recommend testing the pressure settings before using the water flosser. You may begin flossing from the lowest pressure setting to the highest pressure setting progressively. You will gradually get used to the pulsing pressure by the water flosser.

How often do I need to replace my nozzles?

We recommend replacing your nozzle every 3-6 months to prevent hard water build-up. Mineral deposits can collect and reduce performance over time.

Can child use this water flosser?

No, children cannot use W100. It is designed for adults above 18 years old. Consult your dentist if you are unsure.

Can I use mouthwash with water flosser?

No. There is alcohol content in mouthwash which will damage the components in the device.

How long is the warranty period?

1 year.

How do I charge the Water Flosser?

A USB charging cable is included in the kit. You can insert the cable into a USB port. Charging adaptor is not included.

Can I use the water flosser in the shower?

No. You cannot use the water flosser in the shower. The water flosser is not fully water resistant.
