Brief summary: The aim of this study is to evaluate the efficacy of a new interdental cleaning device (Soft-Picks Advanced), as compared to a leading brand floss; and, how ease of use can promote the establishment of a hygienic routine of cleaning interproximal spaces.

Detailed description: The Soft-Picks Advanced has a new curved design allowing a user to easily access to difficult interdental sites, such as spaces between premolars and molars. This study is a single center with parallel design, single blinded, which will randomize eligible subjects into two treatment groups.
