Does drilling teeth kill nerves?

Drilling holes in teeth is a common method of repairing and filling teeth. We know that as dentists, we generally do not kill the dental nerve easily. Only when the dental disease is more serious, such as severe pulpitis, severe apical periodontitis, etc., it is necessary to kill the dental nerve. In this regard, we must pay attention and not kill the dental nerve easily to avoid adverse effects on health.

Under what circumstances should the tooth nerve be killed?

1. Pulpitis: The dental pulp becomes inflamed due to bacterial infection. The dental pulp is in a sealed pulp cavity and is generally not infected by bacteria. When a tooth has a hole due to caries and the hole is too deep, external bacteria will invade the pulp cavity and infect the pulp.

2. Apical periodontitis: After the dental pulp is infected by bacteria, the bacteria will invade the alveolar bone through the apical foramen, causing inflammation of the tissues around the root apex. As long as the infected pulp is removed, the apical inflammation will subside.

3. The tooth is broken and the dental nerve is exposed.

4. When making porcelain teeth, some teeth are not in the normal position. For example, the teeth are too protruding. When the teeth are pulled inward, the outer side of the teeth will be ground too much and may be worn through.

Oral experts said that tooth filling kills nerves, that is, devitalizes the dental pulp, and is used to treat acute or chronic pulpitis. It uses drugs to devitalize the infected dental pulp before performing root canal treatment or plasticization treatment.

Traditional tooth fillings kill nerves and, due to the imperfections in technology and anesthetic techniques, will inevitably cause contact during the operation, which will inevitably lead to pain problems. Nowadays, with the continuous improvement of tooth filling technology and the development of anesthesia technology, tooth filling and nerve killing can be performed completely painlessly. In addition, whether tooth filling and nerve killing are painful or not is closely related to the dentist's skills and the patient's physical condition.

Here, experts point out that when filling a tooth, you must choose a professional and regular dental hospital to avoid infection during the filling process, and this is also very helpful for the effect of the filling.
