Multiple issues: These symptoms are most likley not related, and its a bit too complex to sort out in a short answer online forum. Although these don't sound dangerous, I think you should see your primary care provider for a more complete evaluation. Hope this helps!

2 separate problems: in fact, you have 2 or more separate problems and they need to be addressed separately. 1.A chronic dental abscess. An untreated dental abscess can be life threatening and should not be taken lightly. 2. Multiple medical problems, Treatments for multiple medical problems must be diagnosed and managed together by your PCP.
