question: Dear Doctor,I had four wisdom teeth removed 7 days ago. (Bottom/Top).I am still in lots of pain, Ive had a tingling tounge since the surgery and the last two days have experienced a burning sensation so bad, I cannot sleep. Ive also noticed a strange pressure on the front part of my gums...its getting worse.I also have a whit substance that has formed on my lower and upper gums, it looks like it could come off easily but I dont want to touch it. Do you know what it is? Is it a sign of infection?I havent had a follow up yet. Any feedback?Many ThanksPK
