<s>[INST] 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 [/INST] Hello, Thanks for consulting Chat Doctor Read your query as you have wisdom tooth removal one week ago now you feel pain and tingling sensation on tongue this can be due to lingual nerve injury during anesthesia and deposition of white substance on gums can be material Alba deposition of food debris on gums.Don't be worried so much for this I will suggest consulting oral surgeon for follow-up visit and examination of socket. In meantime do warm saline gargle don't do vigorously, and Betadine rinses. Follow postextraction instructions and take proper course of medicine prescribe by your dentist. Hope this will help you. </s>
