Best oral irrigator for everyday gum health

By Editorial Team | April 2026

Intro: If you hate fiddly string floss or you have braces, implants or tight gaps, a countertop water flosser actually gets below the gumline where flossing often fails. Our top pick for that problem is the Waterpik Ultra Professional (WP-660) because it pairs clinic-backed effectiveness with a large tank and fine pressure control — the features that matter when you need a real clean, not a gimmick.

Best overall: Waterpik Ultra Professional (WP-660)

Waterpik Ultra Professional (WP-660) — £69.26

If your goal is to stop bleeding gums, clean around brackets or keep implants plaque-free, this unit makes that routine fast and reliable. The WP-660 scores 8.2 in our testing and focuses on two practical advantages most people notice immediately: runtime and control.

Why we picked it:

• 650–651 ml reservoir (~90 seconds per fill) so you finish a full mouth clean without stopping to refill.
• Ten pressure settings (≈10–100 psi) plus a 360° rotating tip for targeted cleaning — useful for sensitive gums and stubborn plaque alike.
• Backed by Waterpik clinical claims (up to 99.9% plaque removal in treated areas; better performance than string floss for braces), so this is effectiveness you can measure, not marketing speak.

The trade-off: it’s a countertop unit — noticeably loud at high pressure and bulkier than cordless models, and a mis-seated tip can leak.

If you want a dependable countertop flosser that actually cleans where string floss struggles, the Waterpik Ultra Professional (WP-660) is the practical buy for £69.26.

Best upgrade: Philips Sonicare Cordless Power Flosser 3000

Philips Sonicare Cordless Power Flosser 3000 — £170.85

Paying up gets you a sleeker, cordless design with QuadStream nozzle technology (four narrow jets) that covers more area between teeth quickly, plus decent battery life and IPX7 waterproofing. It’s quieter and more travel-friendly than most countertop units while still offering strong cleaning performance.

Worth it if: you want a quieter, more compact flosser you can use on the go and value a refined nozzle that speeds up full‑mouth coverage. (Philips Sonicare Power Flosser 3000)

Best budget pick: Ordo Hydro Sonic Water Flosser

Ordo Hydro Sonic Water Flosser — £39.99

This is a genuinely usable cordless option at a low price: up to 2,000 pulses/min, three pressure modes and a 260 ml removable tank make it far more practical than tiny travel units. You lose the continuous power and tank size of a countertop model, but you get portability and a device you’re actually likely to use daily.

Worth it if: you travel a lot, dislike cords, or want the simplest route to daily interdental cleaning without spending much. (Ordo Hydro Sonic Water Flosser)

How we chose

We prioritised three things that change outcomes: continuous tank life (so you can finish a cleaning session in one go), adjustable pressure (sensitive gums vs heavy plaque), and clinical evidence or consistent test results. Recommendations were checked against Wirecutter, Electric Teeth, dentist commentary and current UK prices to find options that actually suit braces, implants and daily gum care.

Frequently asked questions

Do water flossers replace string floss? For targeted areas (around braces, implants and periodontal pockets) water flossers are clinically shown to outperform string floss; however, some dentists still recommend combining both methods for full interdental contact depending on your oral health. Use the flosser daily and consult your dentist about adding string floss for tight contacts.

Is the WP-660 worth £69.26? Yes — for its intended users. The price buys a large reservoir, 10 pressure settings and clinical backing that meaningfully reduce plaque in treated areas. If you need portability or a quiet device, the price isn’t the right comparison point.

How often do I replace tips and how do I maintain it? Replace tips every 3–6 months or sooner if worn. Empty and air‑dry the reservoir after use, run plain water through the system weekly, and descale with vinegar or manufacturer-recommended cleaner every 3–6 months depending on local water hardness.
