Periodontal disease is recognized as a significant contributor to tooth loss, particularly after the age of 35. This connection is primarily due to the deterioration of the supporting structures of the teeth, which includes the gums and bone. The disease progresses through various stages, and as it advances, it leads to the breakdown of these foundational tissues, ultimately resulting in tooth mobility and loss.

This relationship underscores the importance of preventive care and early intervention in managing periodontal health, as untreated periodontal disease can significantly affect an individual's oral health and overall well-being. Recognizing the link between periodontal disease and tooth loss helps dental professionals prioritize treatment plans aimed at preserving natural dentition through effective periodontal therapy.

The other statements do not accurately represent established facts about periodontal disease. While antibiotics can aid in specific cases of acute necrotizing ulcerative gingivitis (ANUG), they are not universally applicable to all forms of periodontal treatment. Occlusal trauma can lead to tissue changes, but it does not specifically cause clefts or fibrous thickening of marginal gingivae in the manner described. Furthermore, periodontal pockets cannot all be detected through x-rays; clinical examination is essential for a complete assessment. Hence, the information supports the conclusion that periodontal disease significantly contributes to tooth loss in older adults
