It is a common concern that the jaw might be dislocated during wisdom tooth removal. This perception often arises from the significant pressure and wide mouth opening required for the procedure. This article aims to clarify what actually occurs with jaw movement during wisdom tooth extraction and how any resulting discomfort is managed.
Understanding Jaw Movement During Wisdom Tooth Extraction
Purposeful jaw dislocation is not a standard part of wisdom tooth extraction. The procedure requires the mouth to be held open wide for an extended period, often using a bite block for access. This sustained opening applies considerable pressure and stretching to the temporomandibular joint (TMJ), which connects the jawbone to the skull, and the surrounding ligaments and muscles.
The TMJ allows for the complex movements of the jaw, including opening, closing, and side-to-side motions. During extraction, the condyle, the rounded end of the jawbone, remains within its socket, though it may move to the anterior limit of its normal range. While this can create an intense or unusual sensation of strain in the joint and muscles, it is distinct from a true dislocation, where the condyle completely displaces from its socket. A genuine dislocation is a rare, accidental complication that can occur if the jaw is opened excessively or unexpectedly, not a deliberate step in the extraction process.
Managing Jaw Discomfort Post-Extraction
Jaw soreness and stiffness are common experiences following wisdom tooth extraction. This discomfort is a normal physiological response to the prolonged opening of the mouth, the pressure applied during the procedure, and the subsequent inflammation in the surgical area. The muscles involved in chewing and jaw movement can become fatigued and tender.
To manage this discomfort, applying ice packs to the outside of the jaw for 15-20 minutes at a time during the first 24-48 hours can help reduce swelling and alleviate pain. Consuming soft foods that require minimal chewing, such as soups, yogurt, and mashed potatoes, helps rest the jaw muscles and allows the surgical site to heal without undue strain. Gentle jaw exercises, like slowly opening and closing the mouth within a comfortable range, may be recommended by the oral surgeon after a few days to prevent stiffness and improve mobility. If jaw pain becomes severe, persists for an extended period, or if there is a feeling that the jaw is truly locked or out of place, contacting the dental professional promptly is advisable.
