The best water flosser for cleaning up your oral hygiene (2025)

Long gone are the days of lying to the dentist about whether you floss regularly or not (and trust us, they always know when you're lying). Because flossing has had an upgrade in recent years. These days, it's all about water flossing.

For those who don't know, the water flosser — or oral irrigator to use the technical term — is having a TikTok moment. Indeed, it's the latest trend in hygiene — a TikTok trend that's actually good for you. It will also keep the dentist off your case.

Look, we know the struggle. You're not alone. Flossing can be a hassle, but it is an essential part of maintaining a healthy mouth. For those who can't commit to traditional flossing methods, we recommend checking out water flossers.

Do you actually need to floss?

We're sorry to burst your brushing bubble, but good dental hygiene involves more than just brushing your pearly whites. Brushing is obviously an important part of the process, and still helps to remove plaque and prevent cavities, but you need to do more to keep your teeth healthy and prevent gum disease. Flossing is the answer, because it get in between your teeth to lifts and removes plaque. Flossing helps keep your mouth squeaky clean by reaching all the places that your electric toothbrush can't access. Brushing can only clean the front and back of your teeth, so what about the sides? If you don't clean these areas, you're asking for plaque buildup and gum disease.

How do water flossers work?

It's clear that flossing is absolutely essential, but can you get away with just using a water flosser? The experts at Oral-B state that it's "not recommended to replace traditional flossing with water flossing." Instead, you should incorporate both traditional and water flossing to your daily routine.

Water flossers shoot a stream of water into your mouth to remove food particles and plaque build-up. They get into the periodontal pockets — the gaps between teeth and gums — which prevents gum disease. Another advantage is convenience. There's no fumbling around with slippery floss. They're also great for anyone who wears braces.

How do you use a water flosser?

Water flossers are easy to use, but we'll still breakdown the process so there are no doubts. We're nice like that. Here's a step-by-step guide:

  1. Add water — OK, this might seem obvious, but you'll need water to use your water flosser. Simply fill the reservoir with lukewarm water. Water reservoir capacities will vary model to model.

  2. Aim — Don't start your water flosser without first placing the nozzle firmly in your mouth. We wouldn't want you to spray water all over your bathroom. Aim the device away from your target area rather than directly against your teeth and gums.

  3. Find your perfect pressure setting — At this point you can play around with the water pressure. The pressure should be high enough to actually get the job done, but always start with the lowest pressure setting and work your way up. Water flossers tend to have a selection of pressure levels to chose from.

  4. Direction — Work your way around your mouth, targeting one tooth at a time. Direct the water at your gum line and at the areas between your teeth. There's no golden rule for how long on each tooth, but two seconds is more than enough. Most flossers come with a selection of jet tips that each have a specific cleaning function.

  5. Remove water — We've come full circle, and at this point you just need to turn off the device, remove the nozzle, and drain the remaining water from the reservoir. Don't skip this step — leaving water in your reservoir can result in bacterial growth.

  6. Cleaning — This whole process is about improving your oral hygiene, so it would kind of defeat the point to not clean your water flosser’s reservoir after every session.

Follow these steps and your dentist is going to ask you for tips.

Panasonic DentaCare Series 6000

Best For Healthier Gums

£124.99 Amazon

The best water flosser for cleaning up your oral hygiene (8)

The Panasonic DentaCare 6000 Series might be a bit pricier compared to other options on this list, but it's worth the money. That's because this water flosser is all about premium power and features.

It uses ultrasonic jet technology, which essentially uses a nozzle and water pump combo to create water vapour bubbles. These bubbles then burst on your teeth and gums, making a shock wave that boosts the cleaning power.

You also get five levels of water pressure, four nozzles, and the kind of dexterity you need to get into periodontal pockets. Overall, it's geared towards healthier gums. If there's one drawback, it's the smaller water tank.

The best water flosser for cleaning up your oral hygiene (17)

The Panasonic DentaCare Travel Oral Irrigator is a fairly basic model with just two pressure level settings and a mid-sized water reservoir that will give you up to 35 seconds on constant (not the biggest on this list but not the smallest either). The real bonus is this water flosser's portability.

It has a clever design that allows you to slide the main body into the water reservoir, transforming this flosser into a handy little bundle that you can throw into your bag. In portability mode it measures just 15.4 cm.

It may be small but that doesn't mean you have to skimp on performance. It's still made to get deep between your teeth and get those periodontal pockets clean. That means healthier gums and brighter teeth — even on-the-go.

Waterpik Ultra Professional

The best water flosser for cleaning up your oral hygiene (20)

The Waterpik Ultra Professional Water Flosser lives up to its name. In water flosser terms, this is pro-level stuff. It has a pressure control system with 10 different settings, along with a bigger water capacity that delivers 90 seconds of continuous use. That gives you a very thorough floss indeed.

It also comes with seven jet tips, which includes a selection of tools that have varying teeth cleaning functions.

The only real downside is that it's a bit of a unit. It's mains powered and designed to stay on your countertop. That means this will be a permanent fixture in your bathroom. But with all the power and versatility this model offers, it will be a welcome addition.
