SDF - a tooth decay treatment option

Silver Diamine Fluoride (SDF) is a non-invasive treatment option for some cavities that uses a liquid medicine that is painted on the tooth instead of a drill and fill approach.  Our Lorne Park Dental team is always looking for ways to improve how we do things in order to benefit our patients.  We're excited to be using this treatment in our office.

Now available in Canada, Silver Diamine Fluoride has been used as an agent to stop tooth decay and tooth sensitivity in Japan, China, Germany and other countries for many decades.


  • quick, easy, odourless, painless
  • relieves tooth sensitivity
  • remineralizes your natural tooth structure
  • is the only product available to stop decay in an already formed cavity
  • can be used on both permanent and primary teeth
  • prevents bacterial plaque biofilm from adhering to the tooth surface
  • prevents cavities
  • can help avoid or delay more invasive fillings or restorations
  • ideal for high risk, cavity-prone patients
  • ideal for root surface or difficult to treat cavities
  • can be used if all cavities cannot be treated in one appointment
  • beneficial to patients who require behavioural or medical management
  • no post-treatment limitations for the patient
  • stops 80% of cavities from growing when applied twice year


  • permanently stains cavities black
  • cavities (holes) that trap food may still require a restoration
  • not an option for deep cavities
  • 20% of cavities continue to grow
  • SDF is a treatment for cavities, not a cure

*Proper diet and oral hygiene, including daily between teeth care, are critical for long-term success
