You are seeing a 30-year-old female in a GP setting who has presented with toothache. On questioning, the patient informs you that the pain has come on suddenly over a few hours and has caused her to wake from sleep. She describes the pain as an intense throbbing pain and is also complaining of a fever, an unpleasant taste in the mouth as well as pain when opening her mouth. You examine the area and note facial swelling, regional lymphadenopathy, gum swelling and signs of a decaying tooth. Her observations are as follows: BP 115/80, HR 123, RR 33, O2 saturations 99% on room air and a temperature of 38.4 degrees. What is the most appropriate next step in this patient’s care?
