Waterpik Ultra Review

The Waterpik Ultra Water Flosser has been a core staple in the popular Waterpik flossing line for over a decade. It boasts all the benefits of water flossing in an inexpensive, no-frills device (view on Amazon).

Waterpik is the #1 recommended water flosser brand among dental professionals. Having invented the water in 1962, their continued innovation means that they continue to be the most recognised water flossing brand.

However, with over 20 different products to choose from, it is difficult to know which Waterpik to buy. All Waterpiks are effective but some come with a high price tag, so doing your research can help you get the best for your money.

In this Waterpik Ultra review, we cover everything you need to know when deciding if the Waterpik Ultra is right for you.


  • Removes up to 99.9% of plaque from treated areas
  • Clinically proven to improve gum health up to 50% more than string floss
  • 3x more effective clean around braces

How does the Waterpik Ultra work?

The Waterpik Ultra water flosser utilises patented Waterpik water flossing technology.

Water is pressurized and then delivered to the teeth in a series of ultra-fast pulsations. These pulsations occur at 1400 pulses per minute – too fast to see, but the perfect amount to provide an enhanced clean.

A range of 10 pressure settings allows each individual to tailor their flossing experience to their own requirements.

5 key features unpacked

1.) Pressure settings

The Waterpik Ultra has 10 pressure settings which take you from just 10psi to 100psi for the most thorough clean (view details).

While the highest pressure settings have the most powerful cleaning abilities, 100psi is often too strong to use if you are new to water flossing. For those with sensitive teeth, the maximum pressures may still be too strong.

Having a range of pressure settings ensures that you always achieve a comfortable, but effective clean that is tailored to your requirements.

2.) 1400 pulses per minute

Studies show that pulsating water cleans much more effectively than a continuous stream of water. The Waterpik Water Flosser Ultra projects water that is pulsating at 1400 pulses per minute to achieve an effective clean.

This pulsating cleaning power means that the Ultra is effective even when the pressure is reduced – a great benefit for those with sensitive teeth.

3.) Reservoir

Waterpik Ultra WP-100 in White

The reservoir in a water flosser is the container in which the water sits before it is pressurized and ejected from the tip. For most counter-top water flossers, like the Ultra, this sits on top of the device.

The Ultra’s reservoir has a cover. While it might seem almost insignificant to mention, the cover keeps debris and dirt out of the water flosser. This is essential for the water flosser to do its job fully, and not introduce more bacteria into the mouth.

When the reservoir is completely filled and the pressure set to maximum, the Ultra provides 90 seconds of flossing time. This is quite a large reservoir and means that you don’t have to stop to refill while flossing.

Waterpik recommended flossing for 60 seconds, so this is more than enough to time achieve a really great clean.

4.) Rotating tip

The Waterpik Ultra features a 360 degree rotating tip (view details). This means that it can be repositioned in any direction without moving the handle.

There are two big benefits of this feature:

  1. It allows users to easily clean both the front and back of teeth to make sure that all areas are covered.
  2. It is great for anyone with dexterity issues

5.) 6 included tips

Water flossers will always come with one included tip, and often there is the option to purchase specialist tips at an extra cost.

However, the Waterpik Ultra comes with a variety of 6 tips that allow you to find what is best for you without paying any extra. The tips are color coded which is especially useful if the water flosser is being shared, as each user can quickly identify their unique.

2 Classic Jet Tips (JT-100E)

The Classic Jet Tip is Waterpik’s most used water flossing tip, and 2 are included as a result.

This tip works well for almost anyone and is intended for general everyday use. It cleans deep between teeth and below the gumline where conventional floss cannot reach.

1 Pik Pocket Tip (PP-100E)

The Pik Pocket Tip is intended for use on periodontal pockets and furcations.

The pointed, rubber tip can deliver low-pressure rinses below the gumline, accessing around 90% of the periodontal pocket.

1 Plaque Seeker Tip (PS-100E)

The Plaque Seeker Tip has a soft bristled head which is perfect for cleaning implants, crowns, bridges and other dental restorations.

It has three tufts of bristles which access hard to reach areas around dental work which are particularly susceptible to the buildup of plaque and debris.

1 Orthodontic Tip (OD-100E)

The orthodontic tip should be used with braces and retainers. The combination of the soft bristles and tapered tip allow it to clean around orthodontic brackets and flush out debris and bacteria.

It is proven to be 3x more effective at removing bacteria from around braces than flossing alone.

Who is the Waterpik Ultra suitable for?

The Waterpik Ultra is suitable for:

  • Those with braces and other orthodontic brackets
  • Anyone with implants, crowns, bridges or restorations
  • Periodontal pockets and furcations
  • Anyone who wants a solid and effective device with no frills

Specialist tips allow for a more tailored experience than other flosser on the market like the Philips Sonicare Airfloss.

There are other water flossers available that offer more advanced features such as massage mode (which helps to heal gum disease) and a smart timer. Currently, there are no designer versions of the Waterpik Ultra, meaning you can’t opt for aesthetic upgrades like chrome features.

If you have gingivitis and feel you could benefit from massage mode, take a look at the Waterpik Aquarius (WP-660) which also has a smart-timer to help pace your flossing.
