How long does it take for tooth extraction anesthesia to wear off?

Wisdom teeth are the last teeth in the dental arch and the third molar. Most people grow out between the ages of 16 and 25, so they are called wisdom teeth. Dental experts believe that nowadays people like to eat a delicate diet, which causes the height, width and length of the alveolar to decrease to varying degrees. Therefore, the space allocated to the wisdom teeth is insufficient, resulting in abnormal eruption of the wisdom teeth. When wisdom teeth become deformed, they usually need to be extracted, otherwise it will cause dental disease.
