First let me say, I'm a big chicken when it comes to dentists. Many bad experiences. My lower back tooth is infected again. Hard to bite down. Don't believe it's abcessed. I don't feel any swelling, but the last time it was infected, I went to a dentist and I got an antibiotic to get rid of the infection. I was supposed to go back to have it pulled... and didn't. It comes and goes, the infection under the tooth goes up and down making it hard to bite down on that side. I rinse, floss good back there etc. Trouble is, for 1-2 weeks, I've been having stomach pain. I have IBS anyway, but it's been worse. I had an abdominal/pelvic CT scan this week and showed minor diverticulosis. Doctor today gave me an anti spasm drug called Chlordiazepoxide and Clidinum, a benzo used to treat spastic colon and other intestinal problems. Since this tooth is infected again, can that infection go into my stomach and cause these problems or make my IBS worse? I'm at my wits end because I can't miss any more work. Can the tooth be making these problems? HELP!
