Patient: Description of the condition (onset time, main symptoms, hospital, etc.): I was injured three months ago, the first one on the right side was partly knocked out, the second one was completely knocked into the gum, the third one was knocked out Now the right two teeth are pulled out, ready to set porcelain teeth, after the film examination, the doctor said the right two teeth nerve damage, need root canal treatment, currently did a root canal treatment, the adjacent teeth began to have some pain, and now it has been a week. It’s been a week now, and I still feel that the gums are not suitable. Please ask the doctor: will the root canal treatment hurt the neighboring teeth, is it normal to have pain in the neighboring teeth, if we stop the root canal treatment now, (once done, the doctor said it needs 3 times, the nerve is not finished), and directly set porcelain teeth (4 pieces. (Right 1, 2, 3, 4) is not possible, what will be the effect. I feel that this tooth is not inflamed, there is no need to do root canal treatment, and I am afraid of hurting the neighboring teeth. Beijing Stomatological Hospital Endodontics Ling Jianjun: Root canal treatment will not affect the adjacent teeth, porcelain teeth must be perfected before root canal treatment. Adjacent tooth pain may be a symptom of trauma that did not respond at the time and appeared afterwards, which is very common. Patient: Thank you for your guidance. Some people say that doing root canal treatment, if the tube under too long, will hurt the gums of adjacent teeth and cause oral inflammation, is this view correct. What is the color of a normal nerve after removal? Is it normal to have a pure white one? A live nerve is white, but usually there is blood on the surface and it needs to be rinsed out to be seen. If the nerve is necrotic, it turns gray and has an unpleasant smell. Patient: My nerve was white when I had it extracted. The doctor showed me and told me that a normal nerve is red and I didn’t see any blood (and I don’t know if the milky white thing he showed me was a nerve) and said that this white one of mine was necrotic. According to you, the white one is normal, I have a big loss, I have 3 teeth damaged, the right 3 was knocked out, the right 2 was completely knocked in the nerve without necrosis, the right 1 was knocked in a little nerve necrosis, is this situation possible. I really regret that I did not understand clearly before treatment. Thank you very much for your help, thank you very much! In addition, I do 4 porcelain teeth right 1 2 3 4, of which 3 is the one that was knocked out, 2 has been loosened, 1 and root canal treatment will become brittle, only 4 is good teeth, porcelain teeth will not be strong, will not affect the use of it! As for the tube is too long, I also saw this statement on the Internet, and I do not know what it means. It may be that the root canal file under the long bar, once again to your help to say thank you! Ling Jianjun, Department of Endodontics, Beijing Dental Hospital: No thanks, your understanding is wrong. Under normal circumstances, there must be blood and other tissues around the nerve, so bleeding will accompany the nerve extraction. When the nerve is necrotic due to infection, it will necrolyze and decompose, this process will appear no blood, the nerve gray-white, and then after that it will carbonize and decompose to take out the complete nerve. In addition, even if the nerve is alive now, there are many cases where it must be removed due to trauma or other reasons. It is not possible to determine the damage to a tooth by the appearance of trauma. It is also common for a tooth to appear to be minimally damaged, but the nerve may also have problems. There is obviously no contradiction between what you consulted and what I answered, and what the doctor said to you I did not feel any contradiction with his treatment, because your own lack of medical knowledge, lack of full understanding of what I said, and even more distrust of the doctor, caused your own troubles and more misunderstanding of the doctor, just what I very much do not want to see. If your consultation is to popularize knowledge and answer questions, I am willing to communicate with you, if it is to question the doctor’s treatment plan and practice, I will stop the follow-up communication, this platform is not a place to create conflicts between doctors and patients, if you have questions about the doctor’s practice, why not choose a new medical unit or change the doctor? Without mutual trust, medical treatment is going in the wrong direction. Patient: Thank you for your reply and criticism. Due to my lack of medical knowledge and understanding, and also due to my hope for health (holding a fluke for this tooth, hoping that it is not broken), which caused distrust of the doctor, I am deeply ashamed of this, and I will accept your criticism humbly, thank you! Beijing Stomatological Hospital Endodontics Ling Jianjun: You do not mind, I understand your feelings, although the medical profession is emphasizing the general environment is not good, the policy support is not enough, the treatment of doctors is too low, etc., no matter what the reason, some hospitals, doctors do have their own problems. I don’t mean to criticize you, but I don’t want my answers to cause unnecessary misunderstandings or disputes between you and your doctor if you don’t fully understand the situation. I especially hope that this consultation site is a platform and channel for doctors and patients to communicate and understand each other, rather than creating disputes and distrust, especially in the current medical environment so lack of trust in the era, the need for doctors and patients to work together to reconstruct trust, which has so that doctors can put down the burden of dedicated work, patients can put down the burden of peace of mind to enjoy the fruits of medical treatment.
