Water Flosser Reviews

Panasonic Rechargeable Dental Irrigator (Editor’s Choice)

One of the best water flossers on the market is Panasonic’s Rechargeable Dental Irrigator – our Editor’s Choice. Produced by a reliable brand of oral care products, here’s what else makes this rechargeable model stand out from other electric flossers.

Thanks to its two water jet types, complete with three power settings, you can choose your ideal flossing comfort and efficacy levels. For powerful, high pressure cleaning up to 588 kPA, choose Jet Mode and benefit from a pulsating water jet for a superior clean. Opt for Air in Jet Mode for alternating high-pressure water and shots of air. This mode is ideal for cleaning out a build-up of food particles from periodontal pockets and for gum stimulation as well.

Its removable water tank makes refilling easy, plus you can even stick the tank of this best oral irrigator in the dishwasher for an extra clean finish. The charging station is also easy to wipe clean, while its non-contact surface ensures this oral irrigator has a long lifespan without any water damage. For extra ease of use, the entire unit is wall mountable and there is also on-board nozzle storage. 

On the downside, this model is fairly bulky with a long charge time, although most similar water flossers have exactly the same constraints. Despite its large size, you should still be prepared to fill it up several times during use, which is no real hassle thanks to its easy-to-remove tank. 

Pros:

  • 588 kPA maximum water pressure 
  • Two water jet types
  • Three water power settings
  • Removable water tank
  • Nozzle storage on charging station

Cons:

  • May be too bulky for some
  • Need for frequent refilling may be inconvenient
  • Long charge time can be frustrating if you forget to charge it

Zerhunt Cordless (Luxury Choice)


Treat yourself to the best electric flosser with our luxury choice, the Zerhunt Cordless Water Flosser. This model is a great option for both home and travel use since it is cordless, plus it is IPX 7 waterproof rated.

Thanks to its three cleaning modes, there’s a setting for everyone. Due to its high-powered action, it’s recommended that new users start off with the soft setting before progressing to normal or pulse mode. The memory function ensures that your flosser starts up on the mode that you last used on.  

Charging this model up is extremely rapid, you get up to an impressive 20 days use from just one four-hour charge. The water tank is a good size for a portable model and thanks to its wide opening, it is much easier to fill and clean than many other types of water flossers.

With its 360-degree rotating head and six included nozzles, this oral irrigator can be used by all the family, while the specialist dental plaque and periodontal nozzles make cleaning dentures or massaging gums extra easy. 

Naturally, this model is fairly heavy to use when full and you may find yourself accidentally hitting the mode button when in use. Some users may have difficulty reaching their back teeth, as the nozzles are not angled enough for some, although this all depends on your usage technique and handling. 

Pros:

  • Three cleaning modes
  • Fast four-hour charge
  • Memory function
  • Easy-clean detachable water tank
  • Includes six colour-coded nozzles 

Cons:

  • Mode button may be easily activated by accident during use 
  • May be too heavy when full for some users
  • Nozzles could be a little more angled for better results

Pecham Portable Oral Irrigator (Best Value)

If you’re not sure whether or not to invest in water flosser for your teeth, try out the Pecham Portable Oral Irrigator, our top value choice. 

Choose from three power settings: a soft stream of water for sensitive gums and massaging, normal for strong water pulses, and pulse to deep clean and stimulate your gums. Thanks to its fast four-hour charging time, you won’t have to worry about forgetting to charge it up and being unable to use it for a whole day. What’s more, the smart battery indicator light shows you at a glance when your battery is running low.  

IPX7 waterproof rated, you can use this oral irrigator in the shower and with confidence in your bathroom. Thanks to its fairly large, fully detachable reservoir, cleaning is easy. You can also use the easy-fill opening at the rear for rapid top-ups. Complete with a travel bag, four nozzles and a nozzle storage box, this top-value buy is a great way to try out teeth water flossing for the first time. 

While this is a portable, cordless model, bear in mind that it is a little large for travelling light. It is fairly noisy when in use and you may find that the silicone charge flap doesn’t always hold as firmly in place as it should. 

Pros:

  • Three power settings
  • Fast four-hour charging
  • Smart battery indicator light
  • IPX7 waterproof design
  • Detachable reservoir

Cons:

  • May be too large for travelling light 
  • Silicone charge flap may be a little flimsy 
  • It can be quite noisy during use

Bestope Cordless Electric (Best with Multiple Tips)

The Bestope Cordless Electric Dental Flosser is our best pick if you are looking for a model with a range of tips for a more personalised teeth clean. Considering its high levels of performance and battery life, this is one of the best water flossers for improved dental hygiene. 

This water flosser has five cleaning intensity modes, two more than most regular models. Start off with soft and progress up to high, thanks to the five intensity level lights on the unit, finding your ideal flossing intensity is easy. The included six jet tips plus two brush heads, make getting a deep down and personalised teeth clean possible for everyone.

Thanks to its gravity ball design, you can tilt this flosser at an angle to more easily reach your back teeth for an all-round superior clean that’s easier than string floss. The 300ml tank is removable to allow for thorough hygienic teeth cleaning, as well as having a quick refill opening. Unlike many other cordless versions, this electric water flosser has a long-lasting, high-capacity battery for longer periods of use between charges. 

On the downside, there is no USB to wall plug adapter included, but most people have a spare around anyway. Bear in mind that the tank is fairly difficult to remove, especially for the first time and you may find it a little difficult to get a good grip of this model. 

Pros:

  • Five cleaning intensity modes
  • Gravity ball design for easy tilting
  • Removable 300ml water reservoir
  • Long-lasting, high-capacity battery
  • Includes six jet tips and two brush heads

Cons:

  • Plug adaptor may not be included
  • Could be a little more ergonomic 
  • Some users may find it difficult to remove the tank

Liberex Cordless (Best with Memory Function)

If you are looking for an electric flosser that can be easily adjusted to suit your preferences, then make sure you take a look at the Liberex Cordless water flosser. Not only is this model highly adjustable, but it also has a handy internal memory function so your flosser will automatically start up on your last used setting. 

For a rapid start, select one of the four pre-programmed pressure settings: soft, medium, strong or pulse. If you would like more or less pressure, you can adjust the intensity of your flosser thanks to this unit’s 10 adjustable levels, for a truly personalised deep clean. Thanks to its patented OLED screen, you can easily tell what intensity you are on and how much power you have remaining

Refill your flosser via the quick-fill opening at the rear, or remove the entire 300ml tank. This also allows you to easily clean your tank out as needed, without having to risk using harsh chemicals. Five tips are included with your purchase, including a periodontal, orthodontic and plaque tip, plus two regular ones.

The main drawback to this particular model is its proprietary charging cable, make sure you don’t misplace it. Also, the button placement could be improved and a pause function would be useful rather than having to turn it off each time to empty your mouth.  

Pros:

  • Four preset cleaning modes
  • 10 adjustable intensity levels
  • Digital display with memory function 
  • Removable 300ml tank
  • Includes five tips

Cons:

  • Cannot pause stream which may be inconvenient for some
  • Proprietary charging cable means you won’t be able to charge it if you lose it
  • Button placement could be improved as you may push them by accident

Apiker Oral Irrigator (Best with Large Water Tank)

For frequent water flossing or family use, check out the Apiker Oral Irrigator, our top choice for its large water tank. It is a good buy and comes complete with a wide range of multi-functional tips. 

Unlike bulky, cordless units that are often heavy in your hand and difficult to manoeuvre, this corded model has a slim, light and easy-to-hold head. As the tank is separate, you can tilt the head however you like, with no loss of water flow. You also have the advantage of needing to refill less often, thanks to its large 600ml tank – double the capacity of your standard cordless model. 

With its 10 adjustable pressure settings, simply turn the dial on the main unit to alter your water flossing pressure to suit your preferences and needs. Besides the three colour-coded classic jet tips, you also receive a periodontal, orthodontic, dental plaque, tongue cleaner and nasal floss tips. To ensure you have all of your accessories to hand and they stay in good, clean condition, this oral irrigator has the bonus of coming complete with a handy built-in tip storage compartment. 

As you would expect, given its large footprint, this power flosser unit is less suitable for small bathrooms. Also, it is fairly noisy to use and the water flow could be more consistent, as it can be a little jerky at times. 

Pros:

  • Large 600ml tank
  • Easy to hold and fully tiltable head
  • 10 adjustable pressure intensities
  • Built-in tip storage compartment 
  • Includes eight multi-functional tips

Cons:

  • Large footprint means it may take up too much space on your counter
  • Can be fairly noisy during use
  • Water flow is a little jerky and could be smoother

H2ofloss Rechargeable (Best for Beginner Users)

The H2ofloss water flosser is a good buy if you are looking for a cordless rechargeable model with an excellent battery life. It is also easy to use and great for beginner users. 

Thanks to its five easily selectable intensity levels, you can adjust the flossing water pressure to suit your needs. Choose soft when just starting out with an electric water flosser, or for gum massaging, then progress up to higher levels depending on your gum condition and sensitivity levels. 

The 300ml water tank can be completely removed for thorough cleaning. Thanks to the gravity ball design, this power flosser can be tilted at various angles without any loss of pressure or water flow. Combined with the 360-degree rotational nozzle, you can be sure that you’ll get a deep teeth clean even in those hard to reach areas like the back of your mouth or around tooth implants. 

Another great advantage of this particular model is its long-lasting 2,150 mAH battery that can go between 10-15 days before needing a recharge. Its USB charging cable can be used with regular plug adaptors, power banks and computers. 

Unfortunately, the water tank is difficult to take off, especially for the first time. Other areas for improvement include button placement. Currently, it’s too easy to accidentally press them, and there should be some information on when and how to use the various extra tips. 

Pros:

  • Five adjustable intensity levels
  • Gravity ball design
  • 360-degree rotational nozzle
  • Long-lasting battery
  • Removable 300ml water tank

Cons:

  • Product information could be improved
  • Button placement may be inconvenient for some users
  • Tank may be a little difficult to detach

Oral B Aquacare 6 (Best with Easy Refill)

If you are looking for a gentle introduction to water flossing, the Aquacare 6 by Oral B could be your ideal pick. It is very easy to refill and has a compact, easy to use design. 

Thanks to its three intensity settings, you can adjust the water flow pressure to suit your cleaning needs and gum sensitivity. Adjusting the pressure and changing the nozzle gives you six different cleaning programs, choose between sensitive, medium and intense, then select either the focused or rotational water stream nozzle. You can easily check your selected intensity level via the light-up front panel.

Thanks to its compact design, this electric water flosser is lighter and easier to handle than many other versions on the market. It also benefits from Oral B Oxyjet Technology which enriches your water with microfine bubbles of air. Complete with a charging station and nozzles, it’s a great starter kit that can be kept on its station to ensure you never run out of battery. 

On the downside, unfortunately, this Oral B water flosser is not very powerful, making it less suitable if you are switching from using another more higher-powered model. Also, bear in mind that at 145ml, the tank is a lot smaller than most others and you may find the angle of the water jet makes this version fairly difficult to accurately position. 

Pros:

  • Six cleaning modes
  • Three intensity settings 
  • Compact design
  • Oral B Oxyjet Technology 
  • Includes a charging station and two nozzles

Cons:

  • Fairly small tank capacity may need filling regularly
  • Water jet angle can make it a bit awkward to get the right position
  • May not be powerful enough for some

Uvistare Cordless

If you are looking for a good portable water flosser, then this model by Uvistare is well worth considering. It comes with all of the features and accessories that you need for a clean, healthy smile. 

Thanks to its five intensity settings, you can adjust the water pressure to suit your requirements. Start off on soft and progress to stronger settings as needed by simply pressing the mode button. Rated IPX waterproof, this model is suitable for use in your bathroom, including in the shower. 

To make it easy to clean plaque out those hard to reach areas of the mouth, such as teeth at the back of your mouth, this electric water flosser features a gravity ball design, so you can tilt it without losing pressure. It also charges up quickly and easily, in around five hours with a USB charging cable.

It comes with a handy travel bag and multiple tips included. A choice of six interchangeable jet tip nozzles come with this set, making this water flosser a great choice for anyone looking to improve their oral hygiene, including people with orthodontic appliances and gum sensitivity. The included toothbrush head also means you can use it as a stand-in toothbrush for your trips away.  

This cordless water flosser is, like most others, fairly bulky. Also, the button placement could be improved as it is easy to accidentally change intensity mid-flossing, plus the reservoir attachment points could do with being strengthened. 

Pros:

  • Five intensity settings
  • Gravity ball design
  • Removable 300ml water reservoir
  • Rated IPX7 waterproof
  • Includes travel bag and six interchangeable jet nozzles

Cons:

  • Some users may find it too bulky
  • Button placement could be improved to prevent accidental activation
  • Reservoir attachments could be stronger 

Waterpik Ultra Professional

One of the very best countertop water flossers around, if you are looking for a high performance model with a large water tank, then be sure to take a look at the Waterpik Ultra Professional water flosser. 

This Waterpik model is very easy to use thanks to its lightweight, easy-to-handle flossing unit that attaches to the reservoir via a cable. This allows you to angle it exactly how you need to without any loss of pressure. Use it on Floss Mode for maximum plaque removal, then switch to Hydro-Pulse Massage Mode to improve circulation and gum stimulation. 

Thanks to its 10 pressure intensity settings, it’s easy to find the right flossing level for your gums. Simply turn the dial on the main unit to adjust. The one-minute flossing time countdown with 30-second pacer helps you to floss for the recommended duration, ensuring you get your entire mouth sparkling clean.

Complete with a large 650ml removable water reservoir, for less frequent refills, plus on-board tip storage, this is a highly practical, well designed model. There are seven tips to choose from, including three classic jet tips, one toothbrush tip, as well as a plaque seeker, orthodontic and pik pocket tip. 

On the downside, as you would expect, this flossing unit has quite a large footprint given its generous water reservoir capacity. When in use it does tend to make quite a lot of noise and you’ll need a shaver socket nearby as the power cable is fairly short. 

Pros:

  • Two modes
  • 10 pressure intensity settings
  • Large 650ml reservoir
  • One minute timer
  • Includes seven tips

Cons:

  • Large footprint may take up too much space
  • Can be quite noisy during use
  • Power cable is quite short which may inconvenience some

Water Flosser Buying Guide

Now our water flosser reviews have come to an end, we thought you may be interested in how we chose the items on our list. Also known as oral irrigators, whether you’re new to water flossing or it’s time for an upgrade, here’s how to choose the best water flosser in the UK.

Cordless/Corded

After reading our electric flosser reviews and cordless water flosser reviews, you may be sold on the idea of a portable battery-powered model. Today’s cordless oral irrigators tend to have long battery lives and quick charge times of just several hours. However, some users prefer the extra power you can get from a corded version. 

While some people find corded irrigators to be more restrictive, they are more manoeuvrable and easier to angle around your teeth, plus they also weigh less in your hand when water flossing.

On the downside, you will need extra space for a larger corded unit. You will also need to ensure that you have a nearby socket available to plug it in near to your bathroom sink.

Reservoir Capacity

Countertop water flossers tend to have much larger water tanks that can last for a whole session. You may have to fill up handheld rechargeable models once or twice depending on your needs. As you will already be over your sink, don’t let the idea of refilling countertop models put you off too much. 

If you are looking for a small, travel water flosser, then models with a 150ml capacity will be smaller to pack. They will, however, need to be refilled several times. Larger handheld models tend to have tanks of around 300ml, whereas a countertop flosser starts at around 600ml. 

Intensity Settings

To ensure you get the pressure settings that you need, look out for water jet flossers with enough variety. Basic water flossers tend to have three pressure settings, with superior models offering anywhere between five to ten different levels. The best water flossers should have a water control button, a clear indication of what level you are at, as well as an easy way to adjust your power settings.  

Tips

Even the best water jet flosser around isn’t going to work wonders if you don’t have the right tips that work for you. Look out for special tips that offer a different way to clean your teeth, including orthodontic tips for dental appliances, toothbrush tips for brushing and flossing, plaque removal tips for extra effectiveness and multiple colour-coded classic jet tip if you are going to be using your flosser as a family.

Display

The more options that your water flosser has, the more useful you will find a clear easy to read display. You don’t want to get your settings mixed up, especially if you share your water flosser with another family member.

Cordless water flossers benefit from having a battery indicator on their display so you can tell at a glance just when you need to charge yours up. 

Do Dentists Recommend Water Flossers?

Given the number of water flosser reviews by dentists around, it’s easy to see that dentists do, in fact, often recommend water flossers.

Dentists often suggest getting a water flosser to improve oral health alongside an electric toothbrush and dental floss. Water flossers are an effective tool to prevent gingivitis and gum disease. When combined with regular flossing and brushing, oral irrigators are perfect for optimising your oral health routine and preventing any issues from occurring.

If you have any orthodontic appliances, have tightly spaced teeth, or need to clean more effectively around your gum line, then chances are your dentist has probably already recommended that you invest in a water flosser as opposed to interdental brushes.

As the saying goes, it’s better to be safe than sorry. So, even if you don’t currently have any oral health problems with your teeth or gums, but would like to make sure it stays that way, investing in oral irrigators is a tried and tested way to do so.

Do Water Flossers Work as Well as Regular Floss?

While your dentist may recommend you use an electric toothbrush and a water flosser, most will also recommend continuing to use regular dental floss every day. Here’s why using both types works best.

The best water flossers are a highly effective way to reduce flossing time and remove trapped food particles, plaque and debris from between your teeth. Depending on various elements, you may find that regular dental floss is tricky to use or maybe unsuitable for reaching certain areas. Water flossers can reach all areas of the mouth. True, they can be a little tricky to get the hang of at first, however, once you get to grips with your water flosser, you’ll be amazed how clean your mouth feels after using it. 

However, water flossers can be less effective than traditional floss at removing plaque. For this reason, you may want to give your teeth good flossing with dental floss, then to go over them with your water flosser to remove the plaque that you’ve scraped off completely, as well as any trapped debris. 

Even if you don’t regularly floss with traditional string and don’t really want to start, then using a water power flosser is still a great way to help protect against plaque and clean food debris from your gum line.

When used with regular dental floss and brushing, you have a fantastic three-stage teeth and gum care routine that works to prevent bleeding gums, gum disease and will ensure your smile is cleaner than ever. However, water flossing even without regular flossing is still better than not flossing at all. 

Conclusion

There are plenty of great models out there, but if you are looking for the very best water flosser in the UK, we recommend going for our editor’s choice the Panasonic Rechargeable Dental Irrigator. Providing high-quality performance from a name you can trust, this electric water flosser has all the features you need to improve your dental health.

With its two water jet types, Jet Mode and Air in Jet Mode, combined with three pressure intensity settings, you are sure to find your ideal setting for removing plaque and achieving a highly effective clean. This water jet flosser is also cordless for extra ease of use, so even if you don’t have a plug socket near to your sink, you can still benefit from all of the advantages that a water flosser can bring. 

Complete with a removable, easy to clean and refill reservoir, you can even place the water tank in your dishwasher for routine cleaning. It also comes with a handy charging station with a nozzle storage area to ensure your water flosser is always ready for use.
