<s>[INST] I got my wisdom teeth removed last Friday, April 8. It is now Tuesday April 12. I just put some gauze in my mouth to cover the site but decided to take the gauze out to clean it with a salt water solution. When I took the gauze out, there was like some green and yellow pus on it. Earlier this morning, I accidentally hit the site with my electric toothbrush. It caused some bleeding but stopped after a while. Is the pus some kind of infection or something? [/INST] Thanks for using Chat Doctor. Read your query. The date mentioned is not applicable, as April is a long time back. If you mean August it becomes more logical. The greenish and yellow discharge mentioned in the query suggests infection in the extracted socket. I would advise you to not keep the gauze for the long period as mentioned in the query. This will make the food eaten to get lodged in the place consequently leading to infection. Continue with the salt water gargling. If the pain or swelling increases, consult your dentist. Antibiotics like amoxicillin 500 mg and metro lag will be required on prescription. Hope this was useful. Thanks and regards. </s>
