Pain when opening mouth after tooth extraction

It is normal to experience pain when opening the mouth after tooth extraction. The main cause of this pain is injury to the alveolar bone and gums, which may lead to toothache or gum pain. Patients can take several measures to relieve the discomfort: 1) Take anti-inflammatory medication promptly after the extraction to alleviate pain; 2) Avoid consuming hot or cold beverages for several days following the procedure to prevent worsening of the pain; 3) Maintain good oral hygiene after tooth extraction to prevent gum infection.
