I had all of my top teeth extracted and now have a denture. I noticed aout 3 days after the surgery that i have about 10 whit ebumps on the inside of my cheek. I am really wondering what this is. I have been on Cephalexin to get rid of an infected extraction and perhaps wondering if this is somehow a reaction from the extractions or the medication. SOmeone please help, I only want to go to the doctor if absolutely neccessary. Thank you.
