Hello, I suggest that you consult a dentist and be placed on an antibiotic to control the spread of an infection. Take some anti-inflammatory medication such as Tylenol or Advil to reduce swelling and decrease discomfort. You can continue with chlorahexidine use. You may be shifting your bite or clenching your teeth as a reaction to your discomfort. Something caught in the gum, once rinsed and removed, may take a few days to feel better, but with your symptoms increasing, I suspect there is an untreated infection source that has not yet been diagnosed. This could be a fractured tooth or abscess not yet visible on an X-ray. Once diagnosed, temporary treatment and medication may allow you to return home to complete a more involved dental procedure. You could visit a doctor for an antibiotic prescription and most likely, from your description, be referred to a dentist for additional treatment. Thank you for your inquiry. I hope that you find my suggestions useful and feel better soon.
