What I used to do is take a single high dose (2000mg) of amoxycillin one hour before cleaning. I don't remember where I got this idea, but the periodontist went along with it.

My new primary care physician told me not to do this. So I stopped. Now I wish I had never listened to her. Because now I cannot simply run out to the periodontist because I'm having trouble. I have other ongoing health problems which make travel very difficult, so I have to arrange for a caregiver. I also have to decide if it's worth it, because half the times the travel wipes me out and puts me into bed for days.

My periodontist wants an endodontist to have a look at this, and luckily he was able to recommend one closer to me. I'm trying to get an appointment now.

Also, I just want to add my thanks here for the information and follow-up on all my questions.
