Our take on the Sejoy Water Dental Flosser Cordless Oral Irrigator

The Sejoy Cordless Water Dental Flosser is a rechargeable oral irrigator that uses a pulsed water stream to clear food and plaque between teeth and along the gumline. It weighs about 10 ounces, so it is light enough to hold one-handed at the sink and to pack for travel. It suits people who want a portable flosser without a countertop unit, though it holds less water and runs fewer pressure settings than larger plug-in models. Expect a shorter reservoir and simpler controls than premium rivals, which is the usual trade-off at this end of the market.

Questions and answers

Is a water flosser as good as string floss?
It removes loose food and plaque between teeth and massages gums, but dentists still recommend flossing or interdental brushes for tight contacts. Many people use both.
Can I use it with braces or implants?
Yes. A directed stream is useful around brackets, wires and implant margins. Start on the lowest setting and aim along the gumline.
How often should I refill the reservoir?
The tank is small, so expect to refill once or twice during a full clean. Fill with lukewarm water; add mouthwash only if the manufacturer allows it.
Does it need special water or tablets?
No. Plain tap water works. Some users add a capful of mouthwash, but check the manual first because some additives can clog the pump.
Is it good for travel?
It is cordless and light, so it packs easily. There is no travel case, and the reservoir should be emptied before packing.
