A complete nerve transection will leave an area totally numb. The distribution of the numbers depends upon where the nerve was cut. A partial nerve injury may leave the area tingly or incompletely numb. Finally even if the nerve is not cut the swelling and bruising to the tea can affect the nerve as well. Usually we consider sharp penetrating injuries as likely having nerve lacerations when sensation is lost. A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend ...Read more
Root Canal: I do not believe so. Sometimes injections can cause very mild short term damage if the anesthetic is placed directly on or into the nerve but this is rare and it is short term. How long has it been? Have you seen your md or seen the dentist again; I would. Please get a proper diagnosis and see your md or dds. ...Read more
“will the nerve damage from root canal complication (effusion of sodium hypochlorite) be healed on its own? How long? ” ive been really worried. I'm afraid it will be permanent. Pls help me. Thank you
Possibly...: It will depend on how much was extruded into the tissue, what tooth was being treated, when was it first know that it happened, what therapy was initiated to mitigate the effect. It will take some time for the damaged tissues to recover. ...Read more
Depends where it is: Dentists attempt to remove the entire nerve tissue. If any nerve tissue remains in the coronal portion (closest to the mouth), that is less critical than leaving tissue in the root tip area. If tissue is left in the root tip area, it has the potential to cause the root canal to fail and you would need to have the tooth retreated or extracted. ...Read more
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

Proper evaluation: The first step in treating hypersensitivity is to determine if the condition is reversible or irreversible. Reversible conditions can be treated with various methods like topical Fluoride applications, etc. Irreversible conditions require root canal therapy. I suggest you return to your dentist to have a detailed examination and diagnosis. Good luck. ...Read more
Tooth Nerves: Unfortunately, infected tooth nerves will not heal themselves. When the nerves are infected it usually means that the nerve is dead or dieing. You can control the infection for a short time with a series of antibiotics. However, this will only control the infection temporarily. You will either need a root canal or you will need to remove your tooth. I would try to save your tooth if you can. ...Read more
Had 1st part root canal. That nite got several waves intense, felt like nerve pain. W/ nerve gone has is possible? Now feels uncomfortable, achy.
Possible: If infection had spread into the bone surrounding the tooth, inflammation could cause pain.

1st part root canal, nerve removal 2 weeks ago. Lingering discomfort when put pressure on tooth. Concerned will stay. How long is normal? Pull tooth?
If you are still uncomfortable call the Dentist or (hopefully) Endodontist (Specialist) that is treating you and report your concerns. Without examination we can't adequately diagnose your situation.
Do not fear.: 99% of root canal procedures are painless. The local anesthetics used today are very effective at eliminating pain and patients never feel anything. The only exception is if you have a severe infection with swelling and most dentists will treat you with antibiotic prior to the procedure to insure you will be comfortable during the procedure. ...Read more

Since there won't be as much drilling to get to the nerve, will that make the root canal go any faster?
Failed RCT: A failed root canal can become infected and infections can spread in bone and cause destruction to surrounding bone and tissues. Therefore, it requires prompt treatment-- either re-treatment, surgery or extraction of tooth. See an Endodontist for an evaluation and to discuss treatment options. ...Read more
Sometimes when I drink something cold, my tooth, or what feels like it, shoots a nerve that lasts a good five seconds. Does that mean root canal?
Temporary filling very close to nerve starts hurting months later - should you wait to see if antibiotics cure the pain or go ahead with root canal?
Do you think I should avoid a root canal or a crown by doing a laser nerve treatment for my tooth?
No: If you have an tooth infection or an irritated tooth you must either have root canal therapy or an extraction. Not all, but many teeth will need a crown after root canal treatment. Your dentist will advise you. Laser nerve treatment is a newer way to perform root canal treatment. It's not very popular and by definition it's still root canal treatment. ...Read more
Had a root canal a few years ago, general dentist found a nerve root left, very small infection, should I be concerned?
Unfilled RCT: Small infections can become large infections and cause problems not only to the tooth but your general health. Seek a consult from an Endodontist and General or Restorative Dentist regarding your options. I would not just leave it untreated even if there is no pain or other symptoms present. ...Read more
Every tooth that gets worked on. Ends up being a root canal. Due to hyper sensitivity. Why do I prevent hyper sensative nerves?
Speak with dentist: Have the dentist explain the depth and location of the cavity prior to treatment. Have the dentist show you the full mouth series of x-rays and explain to you, what they anticipate. This way you are fully prepared for the treatment needed. After any restoration, it is a good idea to have temperate foods and beverages, until any sensitivity subside. ...Read more

Yes: This is typically the procedure.Get a more detailed answer ›
How does a tooth survive in the mouth and stay alive after a root canal if there is no nerve left... Wouldn't the tooth die and fall out?
Tooth structure: The tooth is held in place by periodontal ligamentfibersthat run from the tooth to the bone. A root canal does not effect these fibers. However the tooth will fall out if you looses these fibers. This would be caused by periodontal or gum disease and is the reason for good brushing, flossing and regular dental cleanings. The tooth itself is not vital or alive. ...Read more
I was just suffering from sensation, a doctor without educating me about the root canal she has done root canal therapy. Will nerve regrow?
No -It wont.: Without educating? You should go to a teaching hospital if you want to be educated. I am sure the treatment was done with consent. If you were forced to do it talk to your doctor about it. ...Read more
Had 1st part root canal. That night got episodes intense spontaneous pain-like nerve pain. How/why can this happen if nerve removed? Now tooth aches.
Can you tell me about signs and symptoms for a root canal. So I am confused about this. How can my tooth nerve be dead if I didn't even feel anything?
Many signs: Root canal therapy is recommended for 2 reasons. First, when the pulp (nerve) is inflamed. Common signs are extreme sensitivty to cold or unprovoked pain. Second, if the pulp is dead. These are typically painless at first, but can progress to an abscess which could be painful with or without swelling. Either case can be biting tender. It is best to treadt it before it becomes an emergency. ...Read more
Having a root canal today. Now I know Xanax (alprazolam) is not dangerously interacting with local anesthetic could it be reacting with meds used to kill the nerve?
The tooth's nerve root should be dead after my root canal 6 months ago. So, how did I get a dental abcess if all the canals were perfectly done?
Is laser nerve treatment or pulp capping for toothache better alternative than having a root canal? I do not want a root canal! It is a front tooth
Root canal is better: Than pulp capping. Pulp capping will only work if there is a pin point exposure of the nerve and it is still healthy. Tooth ache means the nerve is no longer healthy and root canal treatment (with or without use of a laser) is indicated. See a root canal specialist - endodontist. ...Read more
Neuropraxia is defined as a temporary loss of function of the nerve. Some nerves are purely sensory while others carry both sensory and motor fibers. Traumatic contusion injuries to nerves or nerve compressions can cause Neuropraxia. Sensory nerves like sural nerve in the leg or mixed sensory and motor nerves like the median and ulnar nerves in the forearm & hand ...Read more
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
