Irrigating and lavage compositions

A method for scaling and debriding teeth in the oral cavity of a living animal to remove hard calculus from a subgingival area of said teeth comprising the steps of:

• softening said hard calculus by applying to said area, an oral gel composition comprising:
• an effective amount of water,
• from about 0.05 to about 1.0 percent by weight of a calculus solvating surfactant having a molecular weight of from about 100 to about 400,
• from about 0.4 to about 1.5 percent by weight calcium chelator, and
• scaling and debriding said softened calculus from said area with a scaling tip after said oral gel composition has been applied through a needle passage having a diameter on the order of 0.009 inch without clogging the passage to said area for at least about 2 minutes, whereby said softened calculus is removed from said area.

A method of using a viscous liquid for scaling and debriding to remove calculus and endotoxin from a subgingival area of teeth roots in the oral cavity of a living animal comprising the steps of:

• softening said calculus by applying from a syringe through a needle passage having a diameter on the order of 0.009 inch without clogging the passage to said subgingival area a viscous oral gel composition comprising
• an effective amount of water,
• from about 0.01 to about 5.0 percent by weight of a calculus endotoxin solvating surfactant having a molecular weight of from about 150 to about 250
• from about 0.4 to about 1.5 percent by weight calcium chelator, and
• scaling and debriding said softened calculus from said subgingival area with a scaling tip after said oral gel composition has been applied to said subgingival area for at least 2 minutes, whereby said softened calculus and endotoxin are readily removed from said subgingival.

A method to remove calculus and endotoxin from a subgingival area of teeth in the oral cavity of a living animal comprising the steps of:

• applying from an ultrasonic scaling tip passage having a diameter on the order of 0.009 inch without clogging the passage to said area a liquid oral composition comprising:
• an effective amount of water,
• from about 0.01 to about 5.0 percent by weight of a calculus and endotoxin solvating surfactant having a molecular weight of from about 150 to about 250,
• from about 0.1 to about 5.0 percent by weight calcium chelator, and
• scaling and debriding said area while said oral composition is being applied to said area, whereby calculus and endotoxin are removed from said area.

A method for scaling and debriding teeth in the oral cavity of a living animal to remove hard calculus from a subgingival area of said teeth comprising the steps of:

• softening said hard calculus by applying through passage having a diameter on the order of 0.009 inch without clogging the passage to said area, a liquid oral composition comprising:
• an effective amount of water,
• from about 0.01 to about 5.0 percent by weight of a calculus solvating surfactant having a molecular weight of from about 150 to about 250,
