Shopping at usmile? See all current usmile discount codes and deals, checked regularly.

usmile is an oral-care brand selling electric toothbrushes, portable water flossers and the refills to go with them. The UK range is compact, which makes it easy to shop: two water flossers, one flagship toothbrush, accessories and a set of bundles. The UK site lists a 1-year warranty and a 90-day money-back promise. It suits anyone who wants to start water flossing, people with braces or implants who find string floss fiddly, and anyone who travels a lot and wants kit that packs small.

What's worth a look

• usmile C10 Portable Dental Flosser: currently £62.69 in blue and £69.99 in the other colours, against a listed £99.98. usmile describes it as a compact flosser with a pull-out design, built-in storage for tips, four speed settings and a battery it says lasts up to 95 days. It's the model usmile suggests for first-timers and small bathrooms.
• usmile C30 Cordless Water Flosser: currently £72.45 in pink and £75.99 in black, down from £135. It's the newer of the two flossers and is also cordless and portable. It's worth comparing with the C10 if you want the latest model at a similar price.
• usmile Y20 PRO AI Electric Toothbrush: currently £99.99, listed at £149.99. It pairs with the usmile app to track your brushing, gives bone-conduction voice prompts for each zone, has four preset modes and up to 90 days of battery life. A good fit for gadget fans and anyone who suspects they skip the back teeth.
• usmile Y20 PRO AI Toothbrush x C10 Water Flosser: currently £161, against £239.97. It puts the toothbrush and the C10 together in your choice of colours, so it suits anyone upgrading both at once. More combinations are in the bundles collection.
• usmile Sonicare Toothbrush Head With Air Cushion 1.0: currently £16.99 for two or £31.99 for four. usmile says these fit all its toothbrushes, so they're the ones to stock up on if you already own a usmile brush.
