Sensitivity and soreness in the teeth after tooth extraction is a common food reaction, which is more likely to be caused by local inflammatory stimulation or by damage to adjacent teeth caused during tooth extraction, and this condition may cause such problems to appear. If the adjacent tooth is injured during extraction, it can cause severe edema and local lesions, resulting in inflammation, redness, swelling, pain, and even soreness of the local gums. Once the tooth is damaged, it will be sensitive and sore. In this case, timely observation can be carried out, and the pain and swelling can be effectively relieved by certain anti-inflammatory treatment, and then symptomatic treatment of the tooth can be carried out, and if the loosening is more obvious, it needs to be treated with drugs, which can effectively reduce the occurrence of tooth soreness and sensitivity.
