Why don't you use anesthesia when drilling teeth

Everyone knows that treating teeth is very painful. If the dental disease is serious, you need to go to a dental hospital for treatment. Usually the doctor will give the tooth anesthesia to relieve the pain, but anesthesia cannot be used when drilling, because the doctor cannot accurately find the correct position of the tooth. The correct method must be found through feedback from the patient. Let me give you a detailed introduction below.

When filling a tooth, we usually need a high-speed mobile phone, that is, an electric drill, to remove the decayed parts of the tooth. This punishment is an important reason why many people would rather die than see a dentist. In traditional oral medicine concepts, in order to implement the principle of living pulp preservation, anesthesia should not be used in treatments that do not involve the pulp, because the patient's reaction can provide necessary reference for subsequent treatment plans. If patients are given anesthesia for any caries condition, it may lead to misjudgment by the doctor and delay treatment.

If your tooth is not only sensitive but also very painful when the doctor is drilling, it means that your tooth has been rotten to the dental nerve and you will need root canal treatment to save the tooth. This treatment must be performed under anesthesia.

If there is a risk of nerve rubbing, this is a case of deep caries. In cases of deep caries, the carious tissue is very close to the pulp and the healthy dentin is very weak. The pulp will have a clear response to various stimuli in the caries cavity. During the process of preparing the hole and removing the caries, the patient will also be very sensitive.

In cases of acute caries, the decay often progresses deeper than it appears, but because the disease is short-lived and progresses rapidly, bacteria are generally not present in the deepest parts of the softened dentin. For such cases, if it is judged that the pulp is about to be perforated, a small amount of soft tissue can be appropriately preserved for conservative treatment. Even if the pulp has been perforated, since the perforation point is often in a sterile state, direct pulp capping treatment can be tried with a pulp capping agent.

In cases of chronic caries, due to the long course of the disease, even if the decayed matter can be removed completely, if the remaining dentin is too weak, bacteria and toxins may have already entered the pulp cavity through the dentinal tubules. The prognosis of such cases is often worse than that of acute caries. If pulp perforation occurs in chronic caries cases, the effectiveness of direct pulp capping cannot be guaranteed.

From this we can draw two conclusions:

1. In fact, it is not important whether the nerve is reached or not. In other words, what is really important is to judge whether the pulp has preservation value and hope at this time.

2. Even if all the doctor's operations are in compliance with the regulations, there is no guarantee that the pulp of a tooth with deep caries can be preserved, regardless of whether anesthesia is used or not.

Therefore, more and more doctors have begun to accept the idea that anesthesia can be used when filling teeth and preparing holes.

There is no doubt that after anesthesia, the patient will feel less pain, be more cooperative, and it will be easier to remove the deadly matter and prepare the ideal cavity shape. At the same time, because the patient is unable to respond, the doctor's judgment is required to prepare the hole for anesthesia.

With the continuous development of medical technology, painless treatment has become a trend. Therefore, when filling a tooth, if the patient cannot bear it, we can also use some anesthetics to treat it.
