Waterpik® Water Flosser: Significantly More Effective than Sonicare® Air Floss Pro for Improving Gum Health

Efficacy of two interdental cleaning devices on clinical signs of inflammation: a four-week randomized controlled trial.

Goyal CR, Lyle DM, Qaqish JG, Schuller R. J Clin Dent 2015; 26:55 – 60. Study conducted at All Sum Research Center, Mississauga, Ontario, Canada.


To compare the Waterpik® Water Flosser to the Sonicare® Air Floss Pro (model HX8341) for the reduction of bleeding, gingivitis, and plaque over a four week period.


Sixty-nine subjects completed this four week, randomized, single blind, two group parallel clinical study. Subjects were assigned to one of two groups; Waterpik® Water Flosser plus a manual toothbrush; or Sonicare® Air Floss Pro plus a manual toothbrush. Subjects were instructed on the proper use of each based on manufacturer’s directions. Subjects brushed for two minutes each day and used their assigned interdental cleaning device once in the evening. Gingival health was evaluated by measuring for bleeding on probing (BOP) and using the Modified Gingival Index (MGI). Plaque scores were recorded using the Rustogi Modification of the Navy Plaque Index (RMNPI).


The Waterpik® Water Flosser was significantly more effective than the Sonicare® Air Floss Pro at reducing gingival bleeding for all areas measured. Notably, the Waterpik® Water Flosser was significantly more effective, improving BOP by 54%, MGI by 32%, and 28% RMNPI after four weeks compared to the Air Floss Pro.


The Waterpik®Water Flosser is significantly more effective than Sonicare® Air Floss Pro for improving gingival health.
