Waterpik Cordless Express Water Flosser vs Waterpik Cordless Plus Water Flosser

Both are ADA-accepted Waterpik cordless flossers that remove up to 99.9% of plaque bacteria, so the choice comes down to power and tips. The Cordless Plus is the better buy for most people: it is rechargeable, runs up to 45 seconds per fill, includes 4 tips and a 360-degree rotating tip, and has a far larger owner base (4.2 from 5,332 ratings). The Cordless Express is lighter at 0.73 lb, runs on three AA batteries, and suits travelers who want no charger, but it gives only 30 seconds per fill and 2 tips.

• Choose the Cordless Express if you want a light, shower-safe flosser that runs on AA batteries with no charging and you refill often.
• Choose the Cordless Plus if you want a rechargeable flosser with longer flossing time, more tips and a rotating tip for back teeth.
