PURPOSE: To obtain a nontoxic composition for oral cavity, having preventing action on aggregation of bacteria in formation of dental plaque, suitable for oral cavity, capable of exhibiting effects at a low concentration, containing an effective amount of a polysaccharide such as xanthan gum, tragacanth gum, etc. CONSTITUTION: This composition contains an effective amount of a polysaccharide selected from xanthan gum, tragacanth gum, guar gum, karaya gum, chondroitin sulfuric acid, polygalacturonic acid, sodium alginate,κ/λtype carrageenan. The polysaccharide is used in the concentration of about 0.0025 to about 4wt.% by weight/volume in the composition for oral cavity in an aqueous base. The composition is a substantially solid or pasty material such as a cream for teeth, a toothpaste or tooth powder.
