This animation shows the posterior maxilla (the back part of the upper jaw) after multiple teeth have been extracted in one area – and what can happen without replacement or grafting.

What Happens to the Bone After Tooth Loss?

Posterior maxilla bone loss can occur after multiple tooth extractions in the back part of the upper jaw. When these teeth are lost and not replaced or grafted, the surrounding bone begins to resorb, leading to structural and functional issues.

Posterior Maxilla Bone Loss After Tooth Extractions

After tooth loss, the surrounding bone no longer receives stimulation from chewing. As a result, the body begins to resorb the unused bone. Over time, this leads to:

  • Shrinkage of the jawbone (resorption)

  • Expansion of the sinus into the space left behind (pneumatization)

  • Loss of structural support for adjacent teeth and facial contours

This process not only alters appearance but can also complicate future treatments such as dental implants.

Preventing Posterior Maxilla Bone Resorption

Fortunately, bone loss isn’t inevitable. At Britten Periodontics, we focus on preserving bone through proactive solutions like bone grafting and sinus augmentation. These treatments provide a stable foundation for implant placement and long-term oral health.

Moreover, understanding the early signs of posterior maxilla bone loss can help patients make informed decisions. If you’re facing tooth extractions or have already lost teeth, early consultation is key.
