Waterpik Ultra Professional Water Flosser WP-660UK

The Waterpik Ultra Professional is the gold-standard countertop water flosser: a pressurised, pulsing jet of water that cleans between teeth and below the gumline, clinically shown to be up to 50% more effective than string floss for improving gum health. For the millions who own floss and never use it, it converts a fiddly two-minute chore into a 60-second rinse that people actually stick with. Ten pressure settings run from gentle first-week gums to a high-pressure massage that experienced users swear by, and 1,400 pulses per minute do the dislodging work. The 650ml reservoir holds 90+ seconds of capacity — a full mouth with margin — and seven included tips cover the household: classic jets, orthodontic tips for braces, plaque seekers for implants and bridgework, and a tongue cleaner. It's the flosser dentists and hygienists name first, particularly for braces, implants, crowns and tight contacts where string floss fails or simply doesn't happen. The trade-off is a corded countertop unit that needs a mains socket and a corner of worktop. At £64.99 with 4.3 stars, it's the proven pick for turning gum-health advice into an actual habit.
