Why does it still hurt after the tooth nerve is removed?

When there is a problem with the teeth, people usually go to a doctor for treatment. In many cases, the doctor decides the specific treatment method based on the condition of the teeth. In fact, one method is to remove the dental nerve. Many people are more accepting of this because in everyone's impression, if the dental nerve is removed, the tooth will no longer hurt. In fact, this is not the case. If the dental nerve is removed, the tooth will still hurt.

Why does my tooth still hurt after having the dental nerve extracted?

This indicates that there is pulp leakage at the root of the tooth, that is, when the dental nerve was cleaned, residual pulp was retained at the root, and the root apex may be infected. Generally, the tooth loses its vitality after the nerve is extracted, and there is usually no pain, but the apical area can still feel the nerves. If the gums are still swollen and painful one week after the operation, it is most likely caused by incomplete root canal treatment. Once apical periodontitis occurs, root canal treatment must be repeated.

What is the relationship and difference between endodontics, dental nerves and root canal treatment?

In fact, the dental nerve is only a part of the dental pulp. The pain comes from inflammation of the dental pulp, and root canal treatment is to extract the diseased dental pulp, which is the so-called "killing the nerve". In addition, the root canal treatment steps include the "killing the nerve" link. If there is no dental pulp disease or necrosis, root canal treatment is not necessary. In other words, your cavities can still be filled.

Care after dental nerve removal

1. The tooth that you used to treat the dental nerve will become less hard, so do not use this tooth to eat hard food. Normally, rinse your mouth immediately after eating, especially after eating sweets or drinking milk. When brushing your teeth, use the correct brushing method. The BASSS brushing method is now recommended.

2. Another method is to put a protective cap on the tooth and then put a crown on it after root canal treatment. The main purpose is to protect the tooth. This is because although root canal treatment kills the necrotic material inside the root canal, preserves the tooth and avoids tooth extraction, it does not mean that the treated tooth is exactly the same as the previous "good tooth". Because root canal treatment not only kills necrotic substances during the treatment process, it also kills the dental nerves and blood vessels in the root canal. As a result, the tooth will not get sufficient nutrition, and will be more fragile and lack toughness than other teeth.

3. Once you encounter stones while eating or chew something hard, this fragile tooth is likely to crack. If the crack is serious, the only option left is to extract the tooth. Therefore, in order to make the teeth more durable, it is common to have an inlay or crown placed on the teeth after root canal treatment.

4. Inlay only fills the defective part, while the crown is put on the whole tooth. If the area of ​​caries is not that large and the remaining part of the tooth is still in good condition, it is best to do an inlay. Inlay can reduce the amount of tooth tissue removed, retain more healthy remaining tooth tissue, and significantly enhance the tooth's resistance to fracture. But if the damaged area is large, a crown must be made. After the crown is made, an inlay cannot be made.
