Is slight yellowing of extraction site and light yellow oozing normal 3 days after tooth extraction? most oozing occurs when i sleep ,head elevated.

Normal: Any pain or inflammation and fever or headache .. If there is no other symptoms like that . It is ok . It is just a normal healing process .. Observe for any if the above symptoms and get a checkup if you experience any of the above symptoms.

It is normal : Tooth extraction is a surgical procedure and is not completely risk-free. Pain, swelling, bad breath and infection following surgery is usually at its worst 24 – 48 hours after surgery. After that it should subside more and more every day and after 7 days stop. See your dentist or an oral surgeon for post-op appointment and treatment. Take care.
