Buying advice
Our pick
Best overall: Binefia Water Flosser for Teeth Cordless with 5 Modes, 360° Oral Irrigator (£21.84). A portable water flosser for home and travel, with a USB-charged battery, five pressure settings and different jet tips for everyday use, braces and gum care. The model is the HF-2 in black and white.
What is in the box
The Amazon UK listing names these included components: 1 Binefia water flosser, 2 classic jet tips, 1 orthodontic jet tip, 1 periodontal jet tip, 1 toothbrush jet tip, 1 USB charging cable, 1 user manual and 1 waterproof carrying bag. The flosser is listed at 6.5 x 23 x 4.5 cm and 550 g, with a built-in lithium battery included. The country of origin is China.
What the Amazon UK listing says
Five modes: Soft, Gentle, Normal, Strong and Pulse, so you can set the pressure to suit your mouth. Binefia says it is designed for sensitive teeth and that children can use it too.
Pulses and tank: the brand quotes 1,100 to 1,800 pulses per minute, a 300ml water tank and a 360-degree rotating tip.
Jet tips for braces: a toothbrush jet tip with dense bristles for cleaning around braces, implants and veneers, plus orthodontic and periodontal tips.
Gravity ball and waterproofing: the water tube uses a gravity ball so it keeps drawing water at different angles, and the flosser is rated IPX7, which Binefia says makes it safe to use in the shower.
Battery and timer: a 2,500 mAh battery that Binefia says lasts up to 35 days after a 3-hour charge, a built-in 2-minute timer and a memory function.
The listing also makes awards and plaque-removal claims. We have not checked those, so we do not repeat them here.
What the NHS says about cleaning between your teeth
The NHS says to brush twice a day for about 2 minutes with fluoride toothpaste, and that regular flossing may reduce gum disease, tooth decay and bad breath by removing plaque along the gum line. It says it is best to floss before brushing, that interdental brushes can be used instead of floss, and that your dentist or hygienist can advise you on the best way to clean between your teeth.
Things to check before you buy
Brush as well: a water flosser is extra to brushing, not a replacement for it.
Bleeding gums, gum disease or dental work: if your gums bleed, you have gum disease, braces, implants or have just had a tooth out, ask your dentist or hygienist whether a water flosser is right for you and which setting to start on.
Children: Binefia says children can use it. The NHS says children need help or supervision brushing until they are at least 7, so supervise younger users.

Frequently asked questions
Are water flossers better than floss?
The NHS says regular flossing may reduce gum disease, tooth decay and bad breath, and that interdental brushes can be used instead of floss. It recommends asking your dentist or hygienist about the best way to clean between your teeth, so if you are choosing between floss and a water flosser, ask them what suits your teeth.
How do you use a water flosser?
For this model, fill the 300ml tank, fit a jet tip, choose one of the 5 modes (Soft, Gentle, Normal, Strong or Pulse) and aim the tip along the gumline and between your teeth. The built-in 2-minute timer helps you pace it. Start on a low setting and follow the user manual.
Should I use a water flosser before or after brushing?
The NHS says it is best to floss before brushing your teeth. The NHS also says not to rinse your mouth straight after brushing so the fluoride from your toothpaste stays on your teeth, so many people use a water flosser before they brush.
Are water flossers good for braces?
Binefia includes an orthodontic jet tip and a toothbrush jet tip, which the listing says are for cleaning around braces, implants and veneers. If you wear braces, ask your orthodontist or dentist how they want you to clean around them.
Can you use mouthwash in a water flosser?
The Amazon UK listing does not say whether mouthwash can go in this flosser's tank, so check the user manual or ask Binefia before trying it. The NHS also advises not using mouthwash straight after brushing, as it washes away the fluoride from your toothpaste.
