  • Patent number: 5284648
    Abstract: The invention relates to alcohol-free, oral pre-rinse and rinse emulsions containing cleaning and coating compositions that are non-irritating and low foaming thus allowing a residence time sufficient to condition teeth and gums and disruptively affect the plaque matrix. Such disruption allows for the reduction of plaque build-up by either of two efficacious and convenient mechanisms: (1) immediate removal of disrupted plaque matrix by normal brushing or (2) interruption of plaque forming activity in the mouth by frequently cleaning out plaque and plaque precursors, coupled with reduced attachment of plaque by altering the tooth surfaces with the coating compositions.
