I went to fill my teeth several times, and the tooth that had been cut out of the nerve still hurt

First of all, there are two ways to remove the nerve, one is the inactivation method and the other is the pulp extraction method.

In the case of the deactivation method, the effect of posterior tooth deactivation may be poor due to the action of the deactivator, and it will take several times.

In the case of pulp extraction, it is not painful if the pulp is completely removed, but sometimes there are lateral root canals, or the pulp may not be completely removed.

The above are all methods based on the correct diagnosis of pulpitis by the dentist.

It is recommended that you first use an electronic dentist to diagnose whether it is pulpitis or not, **find it in my space.

If the diagnosis is apical periodontitis, a root canal** is required.

In addition, cotton may be a deactivator or a disinfectant. It depends on the doctor's method.

Don't know what the condition of your teeth is before you see the doctor, what is the diagnosis? What tests were done to you before **?

If it is a tooth extraction nerve, it will generally hurt the first two times, but it will not be in the future, so it is recommended that you change doctors and go to a regular hospital. Remember to bring a case.

It does take 1 to 3 times to draw the nerve, and there will be pain during this time, but the pain is not severe, it is slight. Generally, it is tolerable, but as you described, it should be deliberately asking for your money, cotton stuffed in your teeth, one is anti-inflammatory, and the other is to prevent debris from entering, it is recommended that you change to a dentist to take a look. After all, a toothache is hard to bear.

Tooth decay does not affect the tooth at first.

The tooth god bai meridian of the ministry will not hurt. If the tooth nerve is infected with a little deeper, there will be typical symptoms such as soreness from eating hot and cold things, radiating pain, and night pain, which is pulpitis.

When the dental nerve is infected and necrosis occurs, it will not be painful for a period of time, but the bacteria will invade to the bottom of the tooth root through the canal of the dental nerve, and the gum bone will be infected, forming "apical inflammation". If it is severe, it will form an abscess in the gum bone, swollen gums, slightly loose teeth, floating, persistent paroxysmal pain, very severe bite pain (that is, it hurts very much when touched), these are all very typical symptoms of "acute apical abscess", and this is the case for you now.

Because the doctor cleaned the root canal lumen for you, but did not do a perfect root canal** and filled it directly. A large number of bacteria infect the apical alveolar bone inside, and then it is filled again, and the infection causes a large amount of purulent exudate to hold in and cannot be discharged, and that's it...

It is recommended that you do not go to the doctor, the tooth must now be re-filled and drained to relieve the pain.

After that, it is necessary to completely seal the medicine and reduce inflammation, and fill the root canal lumen through which the fine needle passes before the tooth can be filled. This process must be followed up at least three times before it will be thorough (open drainage - 3 7 days - sealing and disinfection - 1 week - root canal preparation - 1 week - root canal filling and filling).

The symptoms of pain may last for about 3-5 days after filling, but it also depends on the patient's individual situation, if the medical technology is better, the degree of pain can be reduced, if the pain is more uncomfortable, you can take some painkillers first, or take anti-inflammatory drugs to control the infection, which can also reduce the symptoms of pain. During this period, you should pay attention to your diet and do not eat too hard and spicy food, which will cause aggravated pain.

If the tooth does not have a nerve, it will become fragile and need to be repaired with a porcelain tooth.

According to your situation, the first is indeed a cracked tooth and a porcelain crown restoration is required; Second**It does not completely cause apical inflammation and needs to be restarted**, and it is best to check it according to X-rays to determine the final result.

If you start to bite painfully just after filling, see if there is a high point in the occlusion, and you can adjust it. If it appears after a period of use, it is best to go to a follow-up examination to see if there are any lesions such as hidden fissures and apical periodontitis.

Dental x-rays are taken to check the condition of the apex of the painful tooth and rule out apical inflammation.

If not, it is recommended to repair the porcelain crown.

It should be that the root of the tooth is inflamed, try flap curettage.
