Soft-tissue injury post-op (no warning to patient/parent)
What it is
After local anesthesia (especially mandibular blocks in children), the clinician does not warn the patient/parent that the lip/cheek/tongue may stay numb for hours and can be bitten without pain, causing self-inflicted soft-tissue trauma (swelling, ulceration, bleeding). This is preventable with clear instructions and supervision. AAPD explicitly states: Postoperative instructions should include the expected duration of anesthesia and strategies to reduce risk of biting the lip, cheek, or tongue.
Why it happens
• Patient/child explores the numb area ("feels funny") and chews or sucks the lip/cheek • Parent not told to supervise closely until numbness resolves (kids may bite during eating/play) • Clinician doesn't try to minimize residual soft-tissue anesthesia in high-risk patients (young children, special health care needs) • Lack of a standardized post-op script/handout in the clinic workflow
