Waterpik Ultra Professional (WP-660)

If you struggle to clean around braces, implants, crowns or tight interdental spaces, a countertop water flosser replaces fiddly string floss with a faster, easier routine that actually reaches below the gumline. This Waterpik Ultra Professional (WP-660) is the classic countertop choice for people who want clinical-level interdental cleaning without daily finger acrobatics; search terms you’ll use include "water flosser", "oral irrigator" and "best Waterpik for braces". ## What makes it worth it The WP-660 pairs a large 650–651ml removable reservoir with around 90 seconds of continuous flossing per fill, so you rarely need to stop mid-clean. It offers 10 pressure settings (Waterpik lists a 10–100 psi range) and a 360°-rotating tip for targeted cleaning, giving far more control than most cordless models that have limited power modes. Waterpik-backed clinical claims — removing up to 99.9% of plaque from treated areas and being significantly more effective than string floss for braces — mean the device isn’t just convenient, it’s demonstrably effective for the conditions it targets. ## Where it falls short At high pressure the unit is noticeably loud and some users report minor leaking if a tip isn’t seated correctly or the pump isn’t primed; it’s also a countertop appliance so it’s bulkier than travel or cordless options. If you have braces, implants, crowns or simply hate traditional flossing, buy this for reliable, clinic-grade interdental cleaning; if you need a quiet, pocketable or battery-powered flosser, look at cordless alternatives instead.
