It is very convenient to use a water flosser with only one start button. But, this feature can cause unexpected things, if you accidentally press this button. For example, sudden spraying causes a mess in your bathroom since it wets your clothing and towels.

Meanwhile, it’s safer to use the MySmile cordless water flosser that features a mistouch prevention design. This unit requires 3 steps to start: pressing eject button to insert tip, pressing the on/off button, and choosing a suitable mode. Thus, if you don't follow all these steps, the device doesn’t run accidentally.

How To Choose The Most Powerful Water Flosser?

What Is The Most Powerful Pressure Setting?

Although all of you here want to buy a powerful water flosser, I don’t recommend you choose a unit with only a powerful pressure setting.

Choosing one with multiple pressure settings allows you to adjust at a suitable level of water pressure to your individual mouth. This is important because the spaces between your teeth can vary very much and your gum can be normal or sensitive at different times in your life.

Each model has different ranges of water pressure, but most of them range from 10 to 100 psi. This is useful to use in most cases.

Will A Countertop Or Cordless Water Flosser Work Best For You?

You are looking for a powerful model, so a countertop unit is a greater solution in terms of power. However, this type of model takes a lot of space. It is inconvenient to travel with this model. Instead, a cordless device with a compact, portable, and lightweight design is more suitable for traveling with you, but you have to sacrifice the water tank size and power a little.

How Large Is A Water Tank Enough?

The water tank should be large enough to hold a lot of water that you can use for your mouth all at once without refilling. The water tanks of the countertop water flossers are usually larger than cordless models, so they can hold more water. But, this type of unit is more bulky and you can’t take it everywhere. If you need an exact information, here is it:

A 22-ounce water tank is large enough to hold water for running within 90 seconds without refilling.

Do You Need A Built-in Timer?

You can safely use a water flosser as long as you want without time limits, so built-in timer isn’t an essential feature. However, some people said that it’s best to use it within 1 minute, so you can consider this function.

Is A Rotating Tip Useful?

A 360-degree rotating tip allows you to access hard-to-reach areas in your mouth easily. Meanwhile, a stationary head requires you to apply more effort on your part to use your water flosser in different directions.

Which Stream Style Is Better?

A continuous stream of water can be thoroughly rinsed between spaces of your teeth, but it is quick to fill your mouth with water, making you drooled.

A fast and tiny burst of water is slower to fill your mouth with water. If you use a mouthwash or antibacterial solution in your flosser, this is greater because it helps you save more content.

Which Brands Make The Most Powerful Water Flosser?


This is the most famous and respected brand in the water flosser industry. It is proven by many dental professionals who recommend this brand instead of others. Waterpik features over 20 types of water flossers. Some of them include countertop water flossers, handheld, battery-operated water flossers, travel-size water flossers,, complete oral care kits, toothbrush and water flosser combos, whitening water flossers, and tips with accessories.


MySmile has 10 years of experience in oral health and professional teeth whitening. Most of their water flossers are powerful enough to remove up to 99.9% of plaque from difficult-to-reach areas in your mouth.


How strong should a water flosser be?

This depends on each type of water flosser:

Countertop water flossers range from 20 to 100 psi

Cordless models usually have 2 pressure settings: 45 and 75 psi, but it can have another pressure setting: 60 psi.

Can you damage your gums with a water flosser?

Although some people’s gums bleed after using a water flosser for the first time, in fact, this device doesn’t damage teeth and gums. It acts as gentle as flossing on your oral cavity. To avoid bleeding, you need to choose the right settings for the strength and speed of your water flosser.

Do I still need to floss if I use a water flosser?

Yes. Although the water flosser can get rid of food particles from your teeth and minimize the risk of bleeding and gum disease, you can’t use it as a substitute for flossing and brushing. This unit can’t remove visible film and plaque on your teeth.

Can you put hydrogen peroxide in your water flosser?

Yes, you can. Putting a low concentration of hydrogen peroxide (a diluted 3% hydrogen peroxide solution) is completely safe.

Which water flosser heads best?

This depends on your purposes. Let’s check each type of water flosser tip:

A classic jet tip is for daily use because it can deeply clean between teeth and below the gumline to improve your oral health and avoid gum disease.

An orthodontic tip that comes with a tapered brush on the end can remove plaque from braces and orthodontics. It is also useful to flush out food debris and bacteria under the gums and around teeth.

A plaque seeker tip suits for dental work since it can remove plaque in hard-to-reach areas by using its 3 thin tufts of bristles to gently access plaque.

A pik pocket tip is ideal to provide your periodontal pockets with water or antibacterial solution.

A tongue cleaner that looks like a spoon can effectively trap and remove bacteria from your tongue to avoid bad breath.

A toothbrush tip (looking like a manual toothbrush) is common since it is designed for general use. With this tool, manually brushing your teeth is a way to water floss.

An implant denture tip can also access hard-to-reach positions to clean fixed implant bridges and dentures.


Although the most powerful water flosser can help you remove food debris from your teeth quickly and effectively, you shouldn’t just choose a model with the most powerful flossing mode.

A device with multiple water pressure settings allows you to use it with different purposes, for example, regular uses, for children, for adults, your tongue, massage your gums, and access hard-to-reach areas. All products in this article have more water pressure settings, so choose one that can meet your needs.
