Which irrigator to choose? A guide to the best models

Are you wondering, which irrigator to choose? The offer is huge, and the technical parameters can be dizzying. So let's check what to really pay attention to in order to buy a device that will actually help.

What is a dental irrigator and why is it worth having?

Dental irrigator it is a device that releases a pulsating stream of water under pressure. This allows it to reach places where a toothbrush cannot – between teeth, under the gum line, around bridges or orthodontic appliances. Teeth irrigation this is not a whim but an effective way to reduce plaque. Studies also show that regular use of a water flosser reduces bleeding and gum inflammation [1].

Key parameters – what to pay attention to?

Water pressure and pulsation

How to choose a water flosser in terms of power? Look for devices with adjustable pressure in the range of 40–110 PSI and a pulsation frequency of about 1500 movements per minute. Why is this important? If you have sensitive gums, too strong a water stream can irritate them and cause bleeding.

Meanwhile, for stubborn plaque you need more power to remove it effectively. ZENT® Stream+ offers exactly that range and additionally three operating modes: gentle for sensitive gums, normal for daily hygiene, and pulsating for deep cleaning.

Types of nozzles

A standard tip is enough for daily use. But if you wear braces, you need a special nozzle – water flosser for teeth and orthodontic appliances requires exactly such an accessory that reaches under brackets and arches. Meanwhile, flosser for gum pockets should have a thinner, gentler tip. It's good when you get several options in the set – just like with ZENT® Stream+, which has three specialized nozzles.

Battery and mobility

If you travel for business, choose a water flosser for teeth cleaning with long battery life. ZENT® Stream+ works for 35 days on a single charge (6 hours), has a foldable tank, and weighs so little you can fit it in your toiletry bag. That's real convenience.

Flosser for different needs

For children

Water flosser for children must be above all safe and easy to use. Choose models with gentle mode and lower pressure. Children from 8 years old can use the irrigator under your supervision – it's a good way to teach them proper hygiene before gum problems appear.

For people with braces

Braces are a challenge – food debris accumulates around brackets and wires, and the toothbrush cannot reach all the nooks. The orthodontic nozzle effectively cleans spaces around brackets, reducing the risk of cavities during treatment [2]. It's an investment that will help save on costly dental visits.

For people with gum problems

If you have bleeding or swollen gums, a periodontal pocket irrigator can bring relief. Start with the gentle mode – if bleeding persists for more than a week, consult a dentist.

A good irrigator is one you will actually use. So check if it has adjustable pressure (40–110 PSI), appropriate nozzles for your needs, and long battery life if you are often away from home. Pay attention to waterproofing (IPX7 allows using the device in the shower) and noise level – quiet operation means comfort. ZENT® Stream+ combines these features with a 5-year warranty, giving peace of mind for years.

FAQ – frequently asked questions

Can the irrigator replace brushing?

No. The irrigator removes food debris and plaque from places where the toothbrush cannot reach, but it does not replace mechanical cleaning of tooth surfaces. Treat it as a supplement, not an alternative.

How often should I use the irrigator?

Preferably once a day, in the evening before brushing. If you have braces or gum problems, you can use it more often – follow your dentist's recommendations.

Is the irrigator safe for sensitive gums?

Yes, provided you choose the gentle mode and do not use too high pressure. If you notice irritation, reduce the intensity.

Can I use mouthwash in the irrigator?

You can, but only if it is intended for irrigators. Thick liquids can damage the mechanism. Usually, plain water is enough.
