They usually contain a combination of polishing agents, humectants, surfactants, binders, flavorings and fluoride-containing and antimicrobial agents.
  • polishing agents usually contain a combination of polishing agents, humectants, surfactants, binders, flavorings and fluoride-containing and antimicrobial agents.
  • tooth cleaning agents are mainly offered in paste, cream and translucent or transparent gel form.
