One more thing. Shortly after the crown was put on and I started feeling pain in the area around the root of that tooth.. It persisted. And it was scary, because having an infection there is very risky

My periodontist told me to swab the area with Peridex (Chlorhexidine Gluconate). I did that for a few weeks and it worked. But after I stopped the pain came back. So I started swabbing again, but for many weeks. When I stopped the pain never came back, I wish I could tell you how many weeks, but I didn't keep track. .
