Things to Consider Before Buying

There are a few things you may want to consider before buying a cordless water flosser. The following are some of the most important factors that you may want to take a look at:

Water Pressure Control

The water pressure control is the most important aspect of a flosser. Without good water pressure, the flosser will not have the power to clean your teeth out. Depending on your requirements, you should also be able to regulate the water pressure. Typically, water flossers have three modes — normal, gentle and pulse. All three modes are able to regulate water pressure and tend to various oral needs that you may have.

The water pressure is measured in times/minute.

Tank Capacity

The tank capacity is the next important thing to consider. If a water flosser has a decently-sized tank, you will be able to finish off your flossing without needing to refill the tank. The water tank in most upgraded models of water flossers are fully open and can be cleaned with ease. The water tank is also typically removable for ease of use.

For a cordless water flosser, 300 ml seems to be a decent size for the water tank to have.

Number of Nozzles

Most cordless water flossers come with at least four nozzles or jet tips so multiple people in the family can use the same flosser. The more nozzles there are, the greater use you can get out of a single cordless water flosser. In the product review above, seven is the highest number of nozzles a water flosser comes with.


Waterproofing is extremely important and no water flosser is complete without it. Since cordless water flossers operate on batteries, you cannot risk the water tank leaking and damaging the battery. Since the water flosser is also portable, you do not want to restrict your movements. If you are running late in the morning and need to step into the shower as soon as possible, waterproofing will allow you to use the water flosser underneath the shower even.


In a portable water flosser, the battery is of utmost importance. If the battery dies at the shortest notice, the flosser is not really portable. Without the battery, a cordless water flosser’s portability diminishes. Most of the water flossers that have been mentioned above can be fully charged within four hours. How long the flosser can last when it is fully charged is the real test of its portability. Some flossers can last 10 days, others can last a whole month of continuous use. The battery life of a cordless water flosser determines how good it is as a portable device. 

Final Thoughts

Flossing can be quite a laborious task — especially after you have had a heavy and delicious meal, you do not want to come face to face with the remnants stuck in your mouth. With water floss, you never need to look at the mess between your teeth. The pressure of the water will remove any food particles that may be stuck in your teeth and will give you a thorough clean from end to end. Portable water flossers make life much easier while you are traveling or even if you are at work. They are not very expensive and will last you a long time so you can simply keep a spare water flosser in the office or in your travel bag so you never fall behind on your dental hygiene routine.
