Best Water Flossers Features Guide

If you’re lost on what each feature of an electric oral irrigator does or mean specifically, here’s a short explanation of each one.

Water or Air – As you probably would’ve guessed, all water flossers use a water jet stream to remove dental plaque. However, there are certain electric flossers such as the Philips Air Floss that primarily uses a burst of pressurised air with micro-water droplets.

Cordless – Larger electric water flossers are wired to the main unit, but if you’re looking for something a bit more lightweight portable, then a rechargeable oral irrigator is ideal, especially for travelling. Though you must bear in mind that they’re not as powerful as corded machines.

Pressure – The figure shown depicts the amount of pressure (measured in PSI – pounds per square inch) that water flosser exerts. The high the number, the more powerful it is.

Pressure Settings – Many water flossers have a pressure range, and they will allow you to select your desired pressure according to how sensitive your teeth is or how you want the water to be distributed.

Modes – Some of the more advanced electric water flossers has several modes to choose from (basic models will usually just have the standard jet mode). Selecting different modes will adjust the water pulsations.

Reservoir – How much water does the tank hold? The more water it holds, the longer use you can get out of the water flosser before having to top up again.

Water Use – The water usage time goes hand-in-hand with the water capacity, though pressure settings and modes can affect the stated time.

Pause – Also known as water control, this button allows you to pause and resume the water stream whenever you like. This is useful if you need more time to aim the nozzle tip into the right area of your mouth without wasting water.

Waterproof – Very few electric water flossers are waterproof, and those that are, are usually cordless models. Being waterproof allows the oral irrigator to easily be washed and used in the shower.

Timer or Pacer – This function is an indicator that activates after a certain period of time (usually every 30 seconds or 1 minute) to tell the user when to start flossing the other side of the mouth or  when the recommended flossing time is up.

Power Source – What kind of socket is needed for the electric water flosser? Many corded machines use 2-pin plugs for UK shaver sockets with a few using 3-pin plugs for standard UK sockets.

Universal Voltage – A water flosser that can be used internationally is always a benefit, particularly if you decide to take it abroad. Otherwise, you’d have to use a seperate universal power adapter.

Included Accessories – These include all the different types of nozzles and tips that come with the water flosser. Different types of tips are generally designed for specific purposes (particularly in the case of Waterpik tips) such as deep cleaning and cleaning braces.

Water Flosser Nozzles and Tips

  • Waterpik Classic Jet Tip – The regular tip for daily flossing; it provides deep cleaning between the teeth and below the gumline. This tip is recommended to be replaced every 6 months.
  • Waterpik Pik Pocket Tip – Tackles periodontal pockets and furcations with its angled nozzle and pointed tip. This tip is recommended to be replaced every 3 months.
  • Waterpik Plaque Seeker Tip – Using 3 thin tufts of bristles, this tip is designed to remove plaque around implants, crowns, veneers and bridges. This tip is recommended to be replaced every 3 months.
  • Waterpik Orthodontic Tip – This tip has a tapered brush at the end that’s designed to remove dental plaque from braces and orthodontics. This tip is recommended to be replaced every 3 months.
  • Waterpik Toothbrush Tip – This tip acts just like an ordinary manual toothbrush, and allows you to brush and water floss your teeth at the same time. This tip is recommended to be replaced every 3 months.
  • Waterpik Tongue Cleaning Tip – Helps to prevent bad breath by using a spoon-like head to scrape off and wash out bacteria from the tongue. This tip is recommended to be replaced every 6 months.
  • Sonicare AirFloss Nozzle – The standard (and only) nozzles designed for the Philips Sonicare AirFloss Power Flosser.
  • Sonicare AirFloss Pro Nozzle – This nozzle is the same as the one for the standard AirFloss, except that it’s designed to fit Philips Sonicare AirFloss Pro Power Flossers only.
  • Oral B Water Jet Nozzle – Ejects a water stream filled with micro air bubbles for fresher cleaning.
  • Oral B OxyJet Nozzle – This has two jet stream adjustments that both delivers compressed air and water which forms micro air bubbles.
