Q. Dear Dr Moore — I was given Corsodyl today by my Dentist to help in the healing of minor gum surgery. He told me to mix my Corsodyl with water (okay so far); and to rinse with the mixture prior to brushing. I am a bit confused as the information I am finding on-line indicates that I should brush first and then rinse. Which protocol is correct? …and does it really matter? Thanks in advance for your help. Kate
