Causes include infection, inflammation, periodontal disease and possibly autoimmune disease. Keep an eye on her and if she is rubbing, place an e-collar (cone) on her to prevent further rubbing or trauma. Ideally, she should be physically examined by your veterinarian to diagnose the underlying cause. Infection can be treated with a course of antibiotics. PeriodontaI disease will need to be addressed with a complete dental cleaning. If necessary, your vet can biopsy the area to collect samples for pathology.
