Causes of limited mouth opening after tooth extraction

It may be due to tissue damage in the oral cavity caused by tooth extraction, resulting in alveolar bone defects, which could affect oral function and lead to limited mouth opening. In addition, alveolar bone defects can compromise tooth stability; unstable teeth may also contribute to restricted mouth opening. Inflammation or hematoma following tooth extraction can impair oral function and cause limited mouth opening. Patients should pay attention to oral care after tooth extraction to prevent the occurrence of restricted mouth opening.
