How to use anaesthetic for tooth extraction

It depends on which tooth is extracted and what kind of anesthetic we use. The injection method varies according to the situation. Generally speaking, if the upper anterior teeth or the lower anterior teeth are to be extracted, we can do local infiltration anesthesia on the labial side and lingual side. If the posterior teeth are to be extracted, then the buccal side of the upper jaw can do local infiltration anesthesia or local block anesthesia. The posterior teeth of the mandible should be extracted. We normally use block anesthesia of the mandible. The lower alveolar nerve, buccal nerve and lingual nerve are anesthetized together. We call it Trinity block anesthesia.
