Three best oral irrigators

Kailey Fralick

Oral irrigators are excellent tools for removing plaque below the gumline.

You probably brush your teeth twice a day like you're supposed to. But if you're not flossing, you could still end up with cavities or gingivitis. For most people, flossing is an inconvenience, and for those with braces or arthritis, it may be next to impossible. In that case, an oral irrigator is your next best option. If you're new to these products, here's a quick overview to explain what they are, how they work, and how to choose the right one for you. We've also included our picks for the three best oral irrigators on the market.

Considerations when choosing oral irrigators

Oral irrigators provide a concentrated stream of water that powers away plaque and other debris caught between your teeth. They come in two main types: countertop or portable.

Countertop models are larger and, as the name implies, they sit out on your countertop. They plug into an outlet, and the oral irrigator itself is attached to its base and the water reservoir via a tube. You never have to worry about charging these irrigators, and they usually operate longer on a single tank of water than portable models. However, they don't travel well.

Portable oral irrigators are more compact, and they generally use standard batteries or replaceable batteries. The water reservoir is built into the unit, so the reservoir is often much smaller and runs out faster. Portable models tend to be more affordable than countertop oral irrigators.


Once you've chosen the type of oral irrigator, you have to decide which features matter the most to you.

Water reservoir size

The larger the water reservoir, the less often it will need to be refilled and the longer you will be able to use the oral irrigator at a time.


Many oral irrigators come with multiple speed settings, so you can choose the level of pressure that's right for you.

Flossing tips

Some higher-end oral irrigators come with multiple flossing tips that are designed for different applications. Some also have color-coded tips, so different members of your household can each have their own flossing tip.


If you don't feel that you floss for long enough, look for an oral irrigator with a built-in timer.

Noise level

Some countertop oral irrigators can be quite loud, especially on higher settings.


Q. Do oral irrigators work as well as floss?

A. A dentist would probably tell you that an oral irrigator isn't quite as effective as manual flossing for keeping the areas between your teeth clean. However, if you don't floss at all or if you struggle to use regular floss, either because you have braces or a condition like arthritis that makes it difficult, an oral irrigator is certainly a good addition to your dental regimen.

Q. Regular floss irritates my gums. Will an oral irrigator do the same?

A. Many oral irrigators come with several settings so that you can choose the strength of the water pressure. While everyone is different, many people who try oral irrigators find that they are gentler on their gums and cause less bleeding and irritation than manual flossing.
