Catalan police, known as the Mossos d’Esquadra, dismantled two clandestine dental clinics in Esplugues de Llobregat and Olesa de Montserrat, arresting five individuals on charges of professional malpractice and fraud. Investigations revealed that the suspects, who lacked legitimate dental qualifications, operated with unsanitary, rusted equipment and expired medical supplies, causing significant physical harm to patients.
How the Investigation Unfolded
The operation began in April when the Mossos d’Esquadra received reports of suspicious activities at the two facilities. According to local reports from ElCaso.cat, police conducted a two-month surveillance operation to monitor the clinics. Evidence collected during this period included testimonies from patients who paid substantial fees for dental procedures that were either incomplete or performed incorrectly. Following the collection of this evidence, authorities executed a search warrant at both locations, where they discovered the full extent of the fraudulent operations.
The Risks of Unqualified Dental Care
The primary health concern identified by investigators was the severe lack of hygiene in the clinics. Police reported finding medical instruments covered in rust and the use of expired pharmaceutical products. In clinical dentistry, the use of non-sterile equipment poses a high risk of bloodborne pathogen transmission, including hepatitis and HIV, as well as severe localized infections.
Professional dental practice requires rigorous sterilization protocols, such as the use of autoclaves, to ensure patient safety. The use of expired supplies further jeopardizes health, as these products may lose their efficacy or become chemically unstable, potentially leading to adverse reactions during or after treatment.
Charges Faced by the Suspects
The five arrested individuals, aged between 32 and 60, face multiple criminal charges. According to the official police statement, these include:

- Illegal practice of medicine (intrudismo profesional)
- Fraud and criminal deception
- Usurpation of identity
- Abuse of power
- Physical injury resulting from medical malpractice
The suspects, who had no prior criminal records, are currently undergoing judicial proceedings. The police seized computer records and patient registries during the raid, which are now being used to identify additional victims who may have suffered long-term health consequences from the procedures.
How to Verify Dental Credentials
To prevent falling victim to similar scams, patients should always verify that their practitioner is registered with the relevant national health authority. In Spain, this is the Consejo General de Dentistas.
Key steps to ensure safety include:
- Check Registration: Search the official registry of the local College of Dentists (Colegio de Odontólogos).
- Verify the Clinic: Ensure the facility displays an official health registration number required by regional health departments.
- Demand Transparency: Legitimate clinics provide clear treatment plans and documentation regarding the materials and products being used.
Authorities continue to analyze the seized digital evidence to determine the full scope of the financial and physical damage caused by this network. Patients who believe they received treatment at these locations are encouraged to contact the Mossos d’Esquadra to report their experiences and seek medical consultation to address any potential health issues.
