<s>[INST] I have these pockets of pus marks developing on my gums and the inner part of my mouth. I am fighting a bad cold right now. I also broke out with a rash all over my body so I thought it may be from the same thing...a large puss mark just broke on my gum should I see a doctor or a dentist? [/INST] Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have pus formation in your gums, when there is Access formation, may be toothed is carious, then Periapical access is there, or may be there is Periodontal problem then it is Periodontal Access is there so, You should go to dentist then go for proper investigations done IOWA (Intro oral periapical radiograph) , and go for proper treatment Root canal treatment or Scaling and root planning properly, Do warm saline gargle two - three times a day, you will get relief Hope this will help you.  Wish you good health. </s>
