Re: Another question for Jennifer about pain after filling
The nerve is definitely traumatized, but that doesn't mean it has died yet or is dying, especially since cold still bothers it. It's best to let the nerve die on it's own instead of rushing into a root canal procedure. I know it's frustrating and you just want the pain to be gone. It's perfectly understandable. The main thing is to make sure it's known, without a doubt, exactly which tooth is causing the problem. When the nerve has become irritated, it does take some time to heal. The nerve will either heal itself or it will die, but you need to give it some time. The fact that the tooth is causing so much trouble, the pain is off and on, is a good sign that the nerve is still very much alive in it.
You do not want to have root canal treatment until you absolutely have to. The nerve supplies moisture and nutrients to the tooth. A root canal procedure involves removing the pulp tissue (nerve), sterilizing the inside of the tooth, and then filling the inside of the tooth. Once the pulp tissue is gone, the tooth dries out and becomes brittle over time. This is why many dentists recommend having a crown placed on a tooth. This is one of the reasons why it's best to give the nerve a chance to heal and only having the root canal when there is no hope for the nerve.
It is possible that the nerve is dying in the tooth and a root canal will be needed. The pain that travels through your jaw to your ear can mean that an abcess is brewing, but it's not always the case.
Consult with an Endodontist. They can do a variety of tests to determine how alive the nerve still is and whether or not a root canal is needed at this time.
