You may want to go back to your dentist and get it checked out. A course of antibiotics and strong pain medication may be needed. Unfortunately it takes time for it to heal and there's no real way to speed up the healing process.
I wish I had an answer for you, but I am writing to you to see if you have any news on how to treat this, because my husband is going through the same thing. The only thing that has worked for him is a first aid kit for dry socket we bought at CVS last night, but he is still in extreme extreme!! pain. Also can't sleep and not sure who is more frustrated now, me or him! I hope the First aid kit works for you, we are going back to the dentist this week, but he has been back and forth to the dentist for over 1 week now, and they apply this gell (clover oil) but does not do a thing!!! so that is why we did our own research and found that clover oil helps, but has to be done like 4 times a day.....try that.
if you have any other helpful news please tell us. He had his tooth removed 3 weeks ago, and we are still going back and forth. the only promising thing I see is the antibiotics he is on, and this tooth kit we have at home.
