<s>[INST] Hi there. Im suffering with what I thought was/is a tooth abscess as I have what looks like a tiny open cut on my gum next to my molar and my face swells from time to time. Underneath and around my jaw is very painful when pressed and Ive just brushed my teeth and spat out blood. Ive had hot flushes all day too, any ideas as to what may this be? Im 19 years old. [/INST] Hi, Welcome to Chat Doctor forum.  As you describe it appears to be the wisdom tooth, means a 2nd molar tooth behind the 1st molar tooth. As the space there is little, it will tear the gums and stop for while, so cause the infection.  I advise you to consult a dentist, for diagnosis and treatment. If not cured by conservatory treatment, it is to be extracted by surgery.  Take more of green leafy vegetables, pulses, sprouts, and protein rich foods.  Wishing for a quick and complete recovery. Thank you. </s>
