Jaw Bone Loss and Deterioration

When a tooth is removed and not replaced, the jawbone in that area no longer receives the necessary stimulation, leading to resorption. Bone loss occurs most rapidly within the first 18 months but continues throughout life unless treated.

Gum disease gradually destroys the bone that supports teeth. Gingivitis, the earliest stage, can progress into periodontitis, which causes significant bone and tissue loss. Without treatment, this can lead to loose teeth and eventual tooth loss.

Traditional dentures rest on the gum line but do not stimulate the underlying bone, leading to gradual resorption. Over time, this can make it difficult for dentures to stay in place, affecting speech and chewing. Bridges, while supported by adjacent teeth, do not provide stimulation to the area of the missing tooth, which can result in localized bone loss.

Injuries that result in knocked-out or severely damaged teeth can prevent the jawbone from receiving proper stimulation, leading to deterioration over time. Bone grafting can help restore lost bone in these cases.

Teeth that do not have an opposing structure can over-erupt, causing strain and bone deterioration. TMJ disorders, abnormal bite forces, and lack of treatment for misalignment can also contribute to bone loss over time.

This bacterial infection affects the jawbone and bone marrow, causing inflammation and reduced blood supply. Treatment often requires antibiotics and removal of the affected bone, followed by bone grafting to restore function.

Both benign and malignant tumors may necessitate jawbone removal. In such cases, reconstructive bone grafting is often required to restore jaw function and structure.

Some congenital conditions result in missing portions of the jawbone. Bone grafting can be used to restore lost bone structure and improve function.

When upper molars are removed, the sinus cavity can expand due to air pressure, reducing available bone for implants. A sinus lift procedure can restore sufficient bone for implant placement.
