The present invention relates to a new and inventive composition for implant cleaning and/or debridement of hard surfaces in the oral cavity, which comprises optimally activated nanoparticles of TiO2, having a mean particle diameter (D50) of about 10-100 nm at a concentration between 0.5-500 g/L, and H2O2, at a concentration of at the most 7.5% by volume, said composition being antibacterial, without causing microbial resistance, and anti-inflammatory, and wherein said composition further comprises solid microparticles, having a mean particle diameter (D50) of about 100-200 μm at a concentration between 0.5-300 g/L, for improved mechanical debridement and/or cleaning of rough surfaces in the oral cavity and/or on an implant.
