<s>[INST] Hi My gum at the back of my mouth smells like poo if I touch it, at the same side of my mouth my toncil is swollen, it has lots of small white spots on it then a large black like area. My throat is sore.What should I do? Doctor/ dentist or A and E with being weekend? [/INST] thanks for your query, i have gone through your query. the halitosis could be because of the gum infection like periodontal abscess ( because of pus discharge) or pericoronal abscess. it can also be because of the tonsillitis. consult your oral physician and ENT surgeon. you have to get your teeth cleaned and take a course of antibiotics. do saline gargling. i hope my answer will help you. take care. </s>
