Former patients of a Brantford dentist are being urged to get tested for blood-borne infections after potential sterilization lapses, according to health officials. The alert was issued by the Brant County Health Unit following an investigation into infection control practices at the dental clinic.
Health officials issue urgent testing recommendation
The Brant County Health Unit has advised that patients who received treatment from Dr. John Smith at the Brantford Dental Centre between January 2023 and June 2026 should undergo testing for hepatitis B, hepatitis C, and HIV. The recommendation comes after an inspection revealed potential breaches in sterilization protocols, including improper cleaning of dental instruments.
“While the risk of transmission is low, we are taking a precautionary approach to ensure patient safety,” said Dr. Sarah Johnson, Medical Officer of Health for Brant County. “Anyone who may have been affected should contact their primary care provider or visit a testing clinic as soon as possible.”
Investigation details and scope
The investigation began after a routine complaint was filed in March 2026, prompting an unannounced inspection of the clinic. Inspectors found that autoclave sterilization logs were incomplete and that some instruments were not properly processed between patients. The clinic has since been temporarily closed pending further review.
Approximately 2,500 patients are believed to have been treated during the affected period. The health unit is working to notify all potentially impacted individuals by mail, but some patients may have moved or changed contact information.
Expert guidance on testing and symptoms
Blood-borne infections can remain asymptomatic for years, making testing crucial. Hepatitis B and C can cause chronic liver disease, while HIV weakens the immune system. Early detection improves treatment outcomes.
“Testing is simple and often free through public health clinics,” said Dr. Johnson. “We urge patients not to delay, even if they feel healthy.”
The health unit has set up a dedicated hotline and is offering free testing at local clinics. Patients are advised to bring any records of their dental visits.
Broader implications for dental care
This incident has raised concerns about oversight of dental infection control in Ontario. The Royal College of Dental Surgeons of Ontario is reviewing its inspection protocols.
“Patient safety is our top priority,” said a spokesperson for the college. “We are committed to ensuring all dental practices adhere to strict sterilization standards.”
