Due to missing teeth, the jawbone is no longer burdened and subsequently recedes (bone loss). In periodontology, the alveolus is the bony part of the periodontium.
"Alveolus" is the name for the upper jaw-bone cavity and lower jaw-bone cavity. The alveolus is the tooth socket of the tooth root (lat. small hollow, tub). Between it and the tooth root lies the joint-like periodontal gap with Sharpey fibers. The alveolar ridge is a cavity shaped like the root of the tooth, which is elastically suspended in it. If the tooth has more than one root, there may also be more than one alveolus. Single-rooted teeth such as the front teeth and canines are very deeply embedded in the jawbone at the beginning of root formation, multi-rooted teeth are not very deeply embedded in the alveoli.
