Mark the possible cause of the gingival recession.

• A. oral respiration
• B. atypical swallowing
• C. high insertion of the lower lip brake
• D. low insertion of the lower lip brake

Answer: (C)

A gingival recession in this context is best explained by a high insertion of the lower lip frenum. When the frenal attachment sits at or above the mucogingival junction, the lip movements produce a continuous pull on the labial gingiva. This mechanical traction stretches and can erode the gingival margin over time, especially on the lower anterior teeth, leading to recession. A low frenum insertion doesn’t exert that pulling force, so it’s less likely to cause recession. While mouth breathing or atypical swallowing can contribute to other periodontal or alignment issues, they don’t directly account for this localized recession pattern caused by frenal pull. In such cases, addressing the frenal attachment (frenectomy or frenuloplasty) helps eliminate the traction and allows periodontal healing.
