Could vancomycin hydrochloride help a tooth infection that one side of the face is swollen?

Vancomycin is a prescription drug used to treat a certain intestinal condition (colitis). This condition causes diarrhea and stomach/abdominal pain. When vancomycin is taken by mouth, it stays in the intestines to stop the growth of bacteria that cause these symptoms.

Oral vancomycin is poorly absorbed, and ingestion does not result in significant levels of the drug in the body. Therefore, oral vancomycin is limited to the treatment of infections that are limited to the gastrointestinal tract

This antibiotic treats only bacterial infection in the intestines. It will not work for bacterial infections in any other part of the body or for viral infections (such as common cold, flu). Therefore, it also wouldn't be able to have any healing effect on tooth infections.
