Whether or not to anesthetize the extraction of a baby tooth should be decided according to the degree of looseness of the baby tooth. If the looseness of the milk tooth is relatively loose, and the pain during extraction is relatively small, anesthetic drugs can be considered to be coated on the extraction site, without the need to use injection into the anesthetic; if the looseness of the tooth is low, or there is inflammation at the root apex, which is prone to cause a greater sense of pain when extracting the tooth, the use of injections to hit the anesthetic should be considered.
1. Loose milk teeth: If the milk teeth to be extracted are loose, or the new teeth have already erupted and the roots have been resorbed, the difficulty of extracting the teeth is low, and it will not cause greater pain to the children, surface anesthetics, such as bupivacaine, can be used to apply on the labial side of the milk teeth, and there is no need to inject anesthetics into the teeth.
2. Low looseness of milk teeth: If the milk teeth to be extracted are not yet significantly loosened, or there is obvious inflammation at the root tip of the milk teeth, the pain caused by tooth extraction is high, and the simple application of anesthesia drugs can not be effective in stopping the pain, it is necessary to consider local infiltration anesthesia to inject anesthesia drugs into the labial and lingual side of the milk teeth, in order to reduce the pain when extracting the teeth.
When extracting milk teeth, you should go to a regular dental institution, complete the pre-extraction examination, and choose the appropriate anesthesia method under the guidance of the physician, so as to reduce the pain caused by tooth extraction and successfully complete the extraction of milk teeth.
