- Is the MySmile LP221 worth it over string floss?
- It reaches between teeth and along the gumline with a water jet, which many people find easier than string floss, especially with braces. It costs more up front and needs charging, so it is a convenience purchase rather than a cheap one.
- How does it compare with a countertop water flosser?
- It trades pressure and tank size for portability. A plug-in model gives stronger, steadier flow and a larger reservoir; the LP221 runs on a battery and needs frequent refills.
- How long does the battery last per charge?
- MySmile does not publish a firm runtime for the LP221, and real use depends on pressure and session length. Expect several days of once-daily use between charges, and charge it before trips.
- What is in the box?
- The bundle includes the LP221 flosser unit and refill jet tips. Check the listing for the exact tip count and whether a charging cable is included.
- Is it waterproof enough for the shower?
- The body is listed as waterproof, so splashes and shower use are fine. Do not submerge it or leave it sitting in water.
- When is the price lowest?
- Cordless flossers tend to dip during holiday and oral-care sales events. The current best new price is $55.99 at Nordstrom as of November 7, 2026, across three stores.
