What condition does stage 5 of tooth resorption indicate about the dental health of the affected tooth?

Stage 5 of tooth resorption is characterized by the complete loss of hard tissue, which includes the enamel, dentin, and cementum of the affected tooth. At this stage, the tooth is largely replaced with inflammatory tissue, leading to a loss of structural integrity and function. This indicates a severe dental condition where the tooth is no longer viable and typically results in the need for extraction. Recognizing this stage is crucial in dental practices as it helps guide treatment plans for the animal, ensuring appropriate intervention is taken to manage the condition and prevent further complications. Other conditions, such as minor periodontal disease or the presence of healthy gums, would indicate better dental health and do not encompass the severity of stage 5 tooth resorption. Similarly, the notion of potential for recovery is not applicable, as stage 5 typically denotes irreversible damage to the tooth structure.
