Report Question about antibiotics in PANS / PANDAS (Lyme included) Posted July 16, 2011 I haven't been on here in ages - probably a year! - but was looking through some posts and figured I would get on this one to reply. My ds7 had issues with loose teeth, particularly when they would hang out in there for a while. We started bribing him to just yank them out, and that seemed to help. With respect to antibiotics, we consulted some dentists and our doctors and were told that clindamycin was best for tooth-related bacterial stuff. So each time he he's gotten a loose tooth since we figured that out, we've switched to clindamycin for a couple of weeks. Worked great for us.
