In stage 4c, which part of the tooth is typically more affected?

In stage 4c dental disease, the root of the tooth is typically more affected. This stage is characterized by severe periodontal disease where significant destruction has occurred not only to the supporting structures but also to the root itself, which may include loss of attachment and bone. As the periodontal disease progresses, the infectious process often extends deeper, affecting the root and surrounding bone significantly. The severity of this condition leads to potential tooth mobility or even tooth loss if not addressed.

In contrast, while the crown of the tooth may show signs of wear or damage, it tends to be less impacted compared to the root during this stage of periodontal disease, where the focus is largely on the deeper structures supporting the tooth. The periodontal ligament space may also be affected due to inflammation and infection, but the primary concern in stage 4c is the condition of the root and the extent of periodontal attachment loss.
