I have a 7 yr. old Blue Heeler. She was ran over 6 yrs ago. It was her face that took mest trauma. I have not had a problem with her teeth until this last two weeks. Now the right side of her upper face back by the muller is swollen. Her teeth are broke off by the gum line and is obviously infected. I cannot afford medical care at this time. Is there a home remedy I can help to draw out the infection?
