Pain due to anesthetic?

Dear Doc,

I have been having pain on one of my upper teeth for a few months already but I kept on ignoring it because of bad dental experiences. During my past dental works, I've experienced lots of pain because my teeth could not get numbed. My face, half of my tongue and lips would get numbed but not my teeth and entire jaw. I had oral surgeries where I woke in the middle of the procedure and the pain was horrible.

The pain was excruciating so I decided to visit a new dentist. Based from the x-ray, my wisdom tooth was growing toward my molar and had a large cavity in it. I was advised to visit an oral surgeon to have the wisdom tooth removed and to an endodontist to get a root canal treatment in the molar.

I went to the endodontist first. I informed him about my past dentist's problem in getting me numb enough to complete the necessary work. He said he will put me into a deeper sedation. The root canal treatment was carried out successfully. However, few hours after the procedure, I had extreme pain which had spread to the back of my tongue, jaw and up to my ears. The pain seemed to come from the area where they gave me the numbing injection. I was told that the numbness will wear off in a few days but it wore off after a few hours. I was in a lot of pain for 10 days.

After about three weeks, I went to the oral surgeon to have my wisdom tooth removed. A few hours after the extraction, I also had pain in the exact spot it was injected. The ache in my ear and tongue become worse. I can't seem to stand the pain! I am now again afraid to go back and have my stitches removed.

Do you think I could be allergic to the anesthetic or there might be something else which is causing the problem? Please help me! I do not know what to do. I would be forever grateful for your help!

You might be right in your mind about allergy to local anesthesia but i often do not see such patients in routine clinic practice. Allergic reaction is mostly also associated with developing skin rashes, itching, erythema and sometime also breathing difficulty. If you don't have such things after local anesthesia then probably you can rule out allergy. Sometimes pain after local anesthesia might be associated with heating major blood vessel with syringe while injecting, which can cause localized swelling over the injection site (common with upper jaw injections). Other possibility might be remaining infection at the site of extraction.

Effect of local anesthesia usually last for minutes to hours depending on type of anesthesia used. Something you might want to consider for your next procedure to decrease anxiety level is Nitrous oxide. Dentists here in US often use with anxious pt and it works very well. Deep sedation (oral and IV) usually third option dentists considers. And if nothing works out then some surgeons also choose general anesthesia (not often though). I would suggest to talk to your oral surgeon and explain all your symptoms associated with local anesthesia. Best!
