I am a 27 year old female who has hypothyroidism and PCOD. The conditions are well under control. However, I have been noticing plaque on my teeth in the past few weeks. I brush twice a day and I don't understand why I've got the bacterial-food film. Now, there are two questions I want to ask. 1- Is the plaque due to thyroid or the medications I am taking. 2- Is teeth cleaning/ scaling now the option for me? HELP!
