I had a tooth extraction performed a week ago, it appeared to be healing as I expected. I just had a large brownish bad smelling lump pop out of it, i felt an instant relief of pressure (not that I was aware of this sensation until now) but now the extraction site is sensitive and a throbbing sensation is there. What has happened?
Hello and thank you for your question. What you had pop out was either the blood clot that had formed when you had the tooth extracted or old food debris.  This is the same way the other parts of your body shed a scab.  This one happened to be in your mouth.  You are experiencing the sensitivity and throbbing because now you have raw tissue exposed to the outside environment.  This is a normal part of healing.  I would suggest rinsing your mouth out with warm salt water to help keeping the area clean and reduce the swelling.  10oz warm water, 1/2 tsp salt swish and spit 4-6 times a day especially after eating.  Also, you can take NSAIDs such as ibuprofen, at this point I would take 600\u00a0mg every 6 hours as needed for pain.  If the pain continues or gets worse, go into your dentist to be evaluated for infection formation. Best wishes and good health
