The harm of tooth extraction anesthesia to the human body

I believe that many people are afraid of tooth extraction, because tooth extraction is to pull the tooth out of the human body's root, so the process will cause some pain. However, many dentists choose to play mahjong with patients when they are extracting teeth for them, which will make the patients feel less painful during the extraction process. But if a person is given anesthesia during tooth extraction, what kind of harm will it cause to his body?

Anesthesia for tooth extraction is harmless to the human body. The anesthesia is only local and will not affect other parts of the body under appropriate dosage and operation. Therefore, we don’t need to worry about the side effects of anesthesia for tooth extraction. So, what is local anesthesia? Local anesthesia is the use of local anesthetics to temporarily block nerve conduction in a certain area of ​​the body to produce an anesthetic effect, referred to as local anesthesia.

Local anesthesia is simple and easy to perform, safe, can keep the patient awake, has little interference with physiological functions, and has few complications. Suitable for small and medium-sized surgeries that are relatively superficial and limited. However, when used for large-scale and deep surgeries, the analgesia is often not perfect and the muscle relaxation is poor. When used for uncooperative patients, especially children, basic anesthesia or auxiliary anesthesia must be added. Therefore, its scope of application is subject to certain limitations.

Possible side effect of anesthesia for tooth extraction is fainting. Some patients suddenly experience dizziness, chest tightness, pale complexion, cold sweats all over the body, cold and weak limbs, a rapid and weak pulse, nausea, and even difficulty breathing and brief coma when receiving anesthesia injection. This is medically known as syncope. Syncope is generally caused by internal factors such as excessive fear, hunger, fatigue and poor overall health of the patient, as well as external factors such as pain and improper posture that cause temporary cerebral ischemia. Therefore, effective measures to prevent syncope include effective communication with doctors before and during surgery, understanding the treatment process, eliminating excessive tension, and avoiding surgery on an empty stomach.

It can be seen that generally speaking, there are no side effects of anesthesia for tooth extraction, because the dosage is very small and will not cause harm to the human body. However, if some people have weak constitutions or cannot absorb anesthesia, they may experience fainting or allergies. When this happens, you must seek medical attention in time. But generally speaking, there are no side effects of anesthesia during tooth extraction.
