Daegu Dentist Booked After Patient Dies During Implant Procedure | South Korea News

A 69-year-old woman died following an implant procedure in Daegu, South Korea, and police are investigating the case, having booked the dentist in charge on charges of professional negligence. The Daegu Police Agency announced the booking without detention on February 5, 2026.

The incident occurred on February 28, 2025, at a dental clinic in Dalseo-gu, Daegu. The patient, identified as B, experienced cardiac arrest after receiving both narcotic sedatives and local anesthetics during the implant procedure. She was subsequently transported to a hospital for treatment but succumbed to her condition one week later.

Police are currently examining medical records from the time of the procedure to determine if negligence played a role in the patient’s death. A key focus of the investigation is whether the dosage of drugs administered during the procedure was appropriate. To aid in this assessment, the police have requested a review and evaluation of the medical records from a medical advisory agency.

This case echoes a similar incident that occurred in Seoul. On December 30, 2025, a woman in her 70s died while undergoing an implant procedure in Gangnam-gu, Seoul, and that case is also currently under police investigation.

Implant procedures, while generally safe, do carry inherent risks, as with any surgical intervention. These risks can include infection, nerve damage, and adverse reactions to anesthesia. The use of narcotic sedatives introduces additional considerations, as these medications can suppress respiratory function and require careful monitoring during and after administration.

The investigation in Daegu will likely center on establishing the standard of care expected in such procedures and determining whether the dentist adhered to those standards. Factors considered will likely include the patient’s medical history, any pre-existing conditions, the specific type of implant used, the techniques employed during the surgery, and the post-operative care provided.

The police’s decision to seek input from a medical advisory agency underscores the complexity of these cases. Medical experts can provide specialized knowledge to interpret medical records, assess the appropriateness of treatment decisions, and determine whether any deviations from accepted medical practice contributed to the adverse outcome.

The charges against the dentist in Daegu are currently classified as professional negligence, which generally involves a breach of the duty of care owed to a patient. The police opted not to pursue charges under the Act on the Aggravated Punishment of Specific Crimes, a decision reportedly based on the assessment that the task of granting a nomination falls under party affairs, not public affairs. This suggests a nuanced legal interpretation regarding the scope of the dentist’s responsibilities.

The outcome of these investigations could have broader implications for the practice of dentistry in South Korea. Increased scrutiny of implant procedures and anesthesia protocols may result, potentially leading to stricter regulations and enhanced training requirements for dentists. It could also prompt a reevaluation of the informed consent process, ensuring that patients are fully aware of the potential risks and benefits of implant surgery before undergoing treatment.

The Korea Herald, South Korea’s largest English-language daily, reported on the Daegu case, highlighting the ongoing police investigation and the concerns surrounding patient safety. The Korea Times also covered the police request for arrest warrants for a lawmaker and a former Seoul city councilor in a separate bribery scandal, also linked to the 2022 local elections.

These investigations serve as a reminder of the importance of rigorous adherence to medical standards and the need for thorough investigations when adverse events occur in healthcare settings. The focus remains on ensuring patient safety and maintaining public trust in the medical profession.
