Which factor most likely caused the gingival recession observed on teeth #8 and #9 in the reported patient?

• A. Brushing technique
• B. Gum recession due to tooth malposition
• C. Sucking on acidic lozenges
• D. Hormonal changes

Answer: (C)

A habit that keeps acidic material in contact with the gum margin can cause gingival recession. Sucking on acidic lozenges continuously exposes the gingival tissues around the upper front teeth to low pH, leading to chemical irritation and tissue breakdown at the margin over time. When the recession is localized to adjacent teeth like the upper central incisors, it points to a local irritant exposure rather than a generalized mechanical issue. The acids soften and damage the gingival epithelium and connective tissue, promoting recession. Brushing technique tends to cause wear patterns related to how and where brushing is done and usually affects broader areas or follows a specific brushing habit, not just two neighboring teeth. Tooth malposition would create recession tied to alignment and bone support, often with periodontal crowding or thin buccal bone. Hormonal changes can influence gingival inflammation generally rather than producing isolated recession on two teeth.
