Periodontal attachment loss due to applying force by tongue piercing.

This report describes lingual cortical plate loss of the two lower central incisors with second degree mobility in an 18.5-year-old patient. Seven millimeters of clinical attachment losses were detected. For the last 4.5 years, the patient has worn a tongue ornament. The spheres were pressed directly against the periodontal lesion. The metal bar was bent as empirical evidence of the excessive force. Dental practitioners should educate their patients about the risk of oral piercing.
