Phantom pain: When nerves are injured there is sometime a condition where there is "memory" and if the nerve is gone, the rest of the nervous system remembers the nerve and there is the sensation of pain. This is a complex and poorly understood conditon. It happens with loss of limb as well. It also could be inflammation in the root canal itself. Discuss with your dentist or endodontist. ...Read more

I have a sharp pain on my lower gum, same area where I had a root canal and crown done about 2 years ago. Do I need to get the root canal done again or should I rather just take pain medication to suppress the pain as it is not daily.

I have a sharp pain on my lower gum, same area where I had a root canal and crown done about 2 years ago. Do I need to get the root canal done again or should I rather just take pain medication to suppress the pain as it is not daily.

Pain: Pain is nature's way of telling you something is wrong. I definitely would not just take pain medication when needed and wait it out. Over 35 years of experience tells me that at some point this will probably flare up and you will be sorry for waiting. Only a dentist who personally examines you and takes x-rays can determine cause and suggest treatment. Make an appointment asap! ...Read more

I didn't have the advised root canal treatment and now experiencing a painful wobbly tooth. Is it too late to get it done?

Maybe: You might have split the tooth. If that is the case, then it cannot be restored and will need to be extracted. If the infection has worsened, this may have caused increased pain and looseness of the tooth. Should this be the case, then it may not be too late. See the specialist -- the endodontist. Good luck.

Why would i still have pain after a root canal therapy?

Healing: When the root canal is cleaned out by the dentist, the files the dentist uses can go past the apex of the tooth, irritating the bone tissue under the tooth. This may cause some pain following completion of the root canal. Also, if there was an abscess at the tip of the root, this must heal. Such an abscess causes swelling in the bone, which is painful. Once this heals, the pain should subside. ...Read more

Need an opinion about a root canal!? I had a root canal about 4 years ago. The dentist never put a cap/crown on it. Yesterday it started feeling very sensitive to cold. It does not hurt to chew on that side, doesn't hurt when i push on it and heat doesn't

Because : Because the nerve in the tooth was removed during the root canal procedure the tooth is unable to respond to changes in temperature. Though every root canal treated tooth does not need a crown, root canal treated teeth are more prone to fracture due to increased brittleness. Fractured teeth typically cause pain on biting pressure or increase the risk of infection as bacteria can migrate down the fracture. I would look at adjacent vital teeth as the source of your discomfort to changes in temperature either due to root exposure of decay. See your dentist as this is a sign that some treatment is required. ...Read more
