Oral chemical burns result due to ingestion of a chemical accidentally into the mouth, causing burns in the oral mucosa, esophagus, stomach, and upper digestive tract if swallowed. Oral chemical burns mainly happen in children. The current case report describes a rare case of a child who ingested POTASH (potassium hydroxide (KOH) (a caustic chemical used as a detergent in clothes washing in law socioeconomic standard Egyptian places) at home and developed chemical burns that resulted in total ankyloglossia. This case was further complicated through mishandling by a general dentist. This case report describes a detailed protocol for the management of such cases.
