Accessory oral frenulum

What it means

Extra fold of tissue extending from the alveolar ridge to the inner surface of the upper or lower lip.

This finding is assessed by gently retracting the oral mucosa from the alveolar ridge. Typically there is a single maxillary and a single mandibular frenulum located in the midline between the two central incisors. Abnormalities of the alveolar ridges may accompany accessory frenula, but these should be assessed separately.
