Jawbone

The jawbone could refer to the upper jaw (maxilla) or lower jaw (mandible), though it usually refers to the lower jaw only. This bone keeps your teeth held in place. In the case of dental implants, the jawbone secures the screw that integrates with the bone and allows the implant to function like a real tooth.

The jawbone is sensitive in terms of neuromuscular connections, which means it is very receptive to pain. Additionally, the size and position of the lower jaw has a significant impact on breathing and sleeping habits, which is why many people with jaw issues encounter symptoms like sleep apnea.

When bone density is lost in the jawbone, possibly as a side effect of missing teeth for a prolonged period, the patient’s face can appear “sunken,” with a chin that appears to protrude too far. With proper nutrition and support from teeth or implants, the jawbone can be preserved to prevent this issue.
