<s>[INST] I was using an electronic toothbrush and I accidently hit my gum. Now I have a white pus. At first it was hurting for a week and now it doesnt hurt anymore even though the pus is still on my gum. Ive had this for about three weeks now. Should I go to the dentist to check to see if my nerves are not damaged? [/INST] Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have injury by electronic toothbrush don't worry this white pus discharge from gums due to Periodontal Abscess formation.  Don't worry you do warm saline gargle two - three times a day Do chlorhexidine mouthwash twice daily.  You can apply stolen gum paint on painful gums. Consult dentist for Oral prophylaxis and curettage. Hope this will help you </s>
