[|Human|] I had a tooth pulled three weeks ago and it seems to be ok , just saw dentist yesterday to have stitches pulled.  Also have gotten some kind of sinus thing that had subsided and come back worse a few days ago. I just looked in my mouth and the roof of my mouth is noticeably yellow.  Its towards the back and on the sides in the back.  What could this be?
[|AI|]  Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, you have undergone extraction, see what happened is after extraction healing of socket take time of 2 weeks, after extraction we have problem in maintain oral hygiene so as you said you have noticed yellowish at roof of mouth so, it can be opening of minor salivary glands, or it can be due to poor oral hygiene also So, you should do Chlorhexidine mouthwash 2 times a day, brush twice daily, do warm saline gargle, and if you feel some problem like burning sensation or pain at roof of then you consult dentist.  Hope this will help you. Wish you good health.
