Local anesthesia in Dentistry

Numbness of the gums during treatment is one of the most important treatments in dentistry. Considering the level of therapeutic sensitivity and the pain caused by cuts and wounds, it is necessary to numb the teeth. Almost all dental treatments require local anesthesia. Local anesthesia reduces pain during treatment. But this operation requires high precision. Because injecting anesthesia in the wrong area doubles the pain.

Types of local anesthesia in Dentistry

The most common type of local anesthesia is its injection. By knowing and identifying the desired area and injecting it, the patient will feel less pain. Sometimes, depending on the type of treatment and type of anesthesia, no pain will be felt. In some more painful treatments, with sedation anesthesia, the person is conscious. But if the dose of the injected drug is higher, the person will be between wakefulness and sleep. No pain will be felt in this type of treatment. This medicine will slightly confuse the patient.

In some milder treatments, Valium tablets work. This pill is taken one hour before starting the treatment. A more intense type of treatment is required to use strong drugs such as sedation. In such treatments, the person is awake as mentioned. But by injecting a high dose of medicine, a person may fall asleep. But he wakes up with a small movement. Because this drug is an anesthetic between sleep and wakefulness. One type of anesthesia commonly used in treatments is general anesthesia. The patient will become completely unconscious by inhaling the anesthetic or injecting it into the veins. In this case, due to the person’s deep sleep, blood pressure and vital signs should be monitored.

Also, due to the severity of the treatment, the person will experience pain after the anesthesia wears off. For this reason, at the end of the treatment, another anesthetic is injected for post-operative pain. According to the desired treatment and the patient’s tolerance level, the dentist determines the type of anesthesia. Sometimes people have a lower pain threshold. In these cases, by stating this issue, the dentist thinks of measures for him.

Dental local anesthetic injection

This type of anesthesia is used in two shots. The term shot is used for the type of injection in dentistry.

The first type is needle injection in the desired area. This identified area will have the least amount of irritation. The pain caused by the injection lasts only a few seconds.

The second type is to direct the needle to the desired area. It means inserting the needle in the final possible part by applying pressure to the dentist. Often this type of injection causes more intense pain.

Patient’s condition during anesthesia

The person is ready to be injected by sitting on a chair. The patient’s head and heart should be parallel to the ground. Also, the position of the legs should be slightly upwards. Sometimes, due to the doctor’s diagnosis, this type of placement will be different. But often this is a fixed type of posture for anesthesia injection.

How to inject anesthesia

The dentist first injects a few drops of anesthesia. After a few seconds, by touching that area, you will notice the exact injection location. Then he injects a certain dose of anesthetic depending on the type of treatment. The drug should be injected slowly. Because otherwise, the gum tissue will react inversely.

When does anesthesia not take place?

Some people have a weaker ability to numb for different reasons. Nerves in people have different functions. These agents cause a difference in the symptoms of anesthesia. But for almost everyone, there are anti-inflammatory drugs with different dosages. It means that the lack of effect of anesthesia can be treated in all people.

Consequences of Anesthesia in Dentistry

  • Increasing the concentration and precision of the dentist’s work while doing the work
  • Absence of feeling pain in the patient and as a result, the proper position for treatment
  • Absence of sudden movements caused by pain by the patient
  • Better identification and treatment in the desired areas
  • Numbness at the end of the treatment and lack of new pain in the patient
  • Increasing results and efficiency of treatment

Does local anesthesia have complications in dentistry?

Local anesthetics often have complications. Although it is almost impossible not to use them. Because treatment is only possible with anesthesia. But its complications are also inevitable. Next, we will examine the side effects of local anesthetics.

  • After the effects of anesthesia, the patient has a disorder in his speech and facial movements. This is normal for several hours.
  • Visual problems occur in the first few hours after the injection.
  • Dizziness and headache, when the anesthesia wears off, are other side effects.
  • Lack of coordination in the muscles and their lack of control is a common complication.
  • Nausea after anesthesia is one of the most common complications.
  • Symptoms of skin allergies are observed in some patients.
  • Bleeding in the injection area is another side effect.
  • Negative effects on the function of facial organs for several hours are also common.

Effective Factors in reducing local anesthesia in Dentistry

Anxiety is always one of the most common causes of negative effects in anesthesia. Uncontrolled anxieties can undo the effects of anesthesia. It also makes the treatment more difficult for the patient and the dentist.

People who have a history of panic attacks often experience repeated attacks with anesthesia injections. Because the injection reminds them of attacks in the past.

People will feel suffocated during the injection. This feeling occurs due to oral anesthetics. But oral anesthetics will not have such consequences.

People with addiction are also often unable to be affected by anesthetics. But dentists in Toronto also think of measures for such people.
