How long does it take to recover from limited mouth opening due to wisdom teeth?

Generally, limited mouth opening caused by wisdom teeth improves within one week to one month. The details are as follows:

After wisdom tooth extraction, swelling and pain in the mouth commonly occur during the first few days following surgery, leading to restricted mouth opening. This is a normal physiological response. Additionally, because the extraction procedure involves oral muscles and joints, mouth opening may be limited for several days after surgery. Typically, the third to seventh day after extraction represents the peak period of restricted mouth opening. If the patient has good overall health, performs proper postoperative care, and avoids inflammation at the surgical site, recovery may occur within about one week, with resolution of limited mouth opening. However, if the patient has poor physical condition and fails to maintain good oral hygiene, resulting in inflammation at the extraction site, the duration of limited mouth opening may be prolonged and could take up to one month to resolve.

To help relieve restricted mouth opening, applying ice packs during the first few days after surgery is recommended. Patients should rinse their mouth several times daily but avoid vigorous rinsing. Additionally, dietary adjustments such as eating soft foods and minimizing chewing of hard items can reduce extra strain on the oral muscles. If a patient experiences severe difficulty in opening the mouth, prompt medical consultation is advised to rule out possible complications.
