question: I have had a problem with bleeding gums even though I floss daily.  Since using a new on the market toothpaste called Parodontax and continuing my daily flossing this condition has stopped.  Of course I see my hygenist three times a year for a cleaning.  The toothpaste contains 0.454% stannous floride.  My hygenist says I should not use a toothpaste unless it has ADA approval on the label.  This toothpaste does not.  Is this formula safe to use?g
