This morning I woke up with a yellow bump on the socket where my wisdom teeth were removed (3 years ago). It was so big it couldnt bite down without it hurting and touching the upper teeth.  After about an hour of being up it began to ooze.  Im not sure what though.  I have had gauze on it all day and it is starting to shrink I am just wondering what it is.
Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have mentioned that you have yellow bump after removal of wisdom tooth after 3 years it can be due to Periodontal problem, may be formation of periodontal access, yellow bump can be Sinus opening, For this you should consult dentist and go for investigations IOWA X-ray and go for treatment, Do warm saline gargle two - three times a day Hope this will help you.  Wishing you good health Regards
