Short Answer
Yes. Tooth or gum swelling should be separated before interpreting the pain as jaw-function related.
How to think about it
Swelling, pus, fever, severe tooth pain, or loose teeth can point toward dental or periodontal problems. Jaw pain can occur around those problems, but the dental source should be checked first.
