[|Human|] A few days ago, I had a terrible toothache.  It was on a tooth that already had a root canal done on it. The tissue surrounding the tooth was very swollen, especially on the roof of my mouth.   It was on the weekend and I could not stand the pain, so I visited the ER.  In the ER, the Dr. gave me a shot to numb the area (just like at the dentist), a rx for anti-biotic and pain pills.  The tooth pain went away and was replaced with a severe raw feeling on the roof of my mouth on the side where the toothache was.  I also have a canker sore on the inside of my lip and 2 cold sores trying to form on my upper lip.  I am in so much pain!  Help!
[|AI|]  Thanks for your query, I have gone through your query. The pain and swelling over the gums can be secondary to tooth infection or gum infection. This can be because of improper root canal treatment, or it can be because of deposits causing gum infection. Nothing to be panic, consult an oral physician and take a radiograph to confirm the diagnosis. Once it is confirmed, it can be treated with root canal treatment or scaling and root planing. The soreness over the lip can be an authors ulcer secondary to stress. Nothing to worry, you can take topical anesthetic and analgesic like lidocaine and choline salicylate respectively. I hope my answer will help you, take care.
