MarketplacePeriomed RinsePosted on January 24, 2010. Can I put on my teeth periomed directly in a drawer while I sleep? Thank you in advance!? Periomed says you have to dilute it in water, and should be used as a rinse. It has a high content of fluorine that is beneficial for teeth. Yes, you must dilute it first or you have sensitive teeth CommentsThere are no comments.Leave a Comment | Popular My Friends |
