What role do defective restorations play in periodontal disease?

Defective restorations can significantly contribute to periodontal deterioration by creating conditions that favor the accumulation of plaque and bacteria around the gumline. When restorations are improperly fitted or damaged, they can form gaps, irregular surfaces, or rough areas that encourage the retention of food particles and bacteria. This leads to plaque formation, which can irritate the gums, promote inflammation, and, if not managed, advance to periodontal disease.

Furthermore, the presence of defective restorations may compromise the overall stability and health of the surrounding periodontal tissues. Over time, this can result in bone loss, gum recession, and increased pocket depths, all of which are characteristic of advanced periodontal disease. Addressing restoration defects is essential for maintaining periodontal health, as it helps create a more favorable environment for oral hygiene and reduces the risk of periodontal complications.
