Our Favorite Water Flosser
Braces, crowded teeth and kids who swear they flossed: string floss rarely happens in a busy bathroom. The water flosser we chose is the AquaSonic Aqua Flosser: it's cordless and rechargeable, simple enough for an 8-year-old, and comes with five jet tips so a couple of kids can share the handle. Here's the one we chose, plus a few others we seriously considered.

AquaSonic Aqua Flosser – Cordless Rechargeable Water Flosser for Teeth – Waterproof, Portable Oral Irrigator for Dental Cleaning with 5 Jet Tips – Braces Home Travel
This is the water flosser we actually keep on the counter. It is easy enough that even our 8-year-old uses it, the tank holds plenty for a couple of kids in a row, and it makes flossing something they will actually do.
Check price on AmazonBefore you buy, check four things: Cordless or countertop, because a cordless flosser goes anywhere and travels, while a countertop unit has a bigger tank and steadier power. Tank size, since a small tank runs dry halfway through a mouth of braces. Pressure settings, so a younger kid can start gentle and a teen with braces can turn it up. Extra tips, because each person in the house needs their own, and orthodontic tips help with brackets.
If several people share one bathroom, a countertop model with a big reservoir is easiest. For one person, travel or a small counter, a cordless handheld does the job.
The AquaSonic Aqua Flosser at the top is the one we chose. Below it are the others we considered: the Waterpik Aquarius if you want the classic countertop flosser, the Waterpik Cordless Advanced for a trusted cordless option, and a couple of compact travel flossers that fit in a dopp kit.

Traditional flossing and our children have never gotten along. Ask any of the six to run string between their teeth and you get dramatic sighs, half-effort, and a tangle abandoned on the counter. Our oldest, especially, has back teeth that catch everything, and getting him to floss consistently felt like a lost cause — until we tried handing the job over to a stream of water instead of a stubborn string.
The tool that finally clicked was the COSLUS Water Dental Flosser C20, and the fact that it is ADA Accepted gave Mom the confidence it was doing real work, not just spraying water around. It is easy for the kids to aim, it clears out the spots their toothbrush misses, and it turned a dreaded chore into something they will actually do because it feels more like a gadget than a lecture. For a house where getting cooperation is half the battle, that shift alone made it worth it.
We compared it to the big countertop water flossers, but those hog space we simply do not have with this many people sharing one sink, and they cost quite a bit more. The COSLUS C20 is compact, refills quickly, and charges up to last a good while between plug-ins, which suits our crowded bathroom perfectly. At around thirty-three dollars it was an easy yes, and it has held up to daily use from multiple pairs of not-especially-gentle hands. It does the one job we needed — cleaner teeth with far less arguing — and for us that is the whole point.
