What causes the underlying jawbone to resorb or deteriorate after tooth loss?
Answer
The absence of the stimulus normally provided by biting and chewing
When a natural tooth is lost, the vital mechanical stimulus that results from biting and chewing forces traveling down the root and into the alveolar bone is consequently removed. The jawbone relies on this regular transmission of functional pressure to maintain its density and structure. Without this ongoing stimulation, the bone tissue begins a process of resorption, meaning it deteriorates and shrinks over time. This deterioration can lead to noticeable changes in a patient's facial appearance and alterations in their bite alignment.
