SDF, or sodium diamine fluoride is a liquid antimicrobial that is applied at the dental office to stop the progression of small cavities. It is a conservative approach to managing dental decay. When applied to a cavity, it can remineralize, or strengthen the cavitated tooth structure. The procedure only takes a few minutes. It’s quick, and doesn’t require any anesthetic.

Frequently Asked Questions

What situations may SDF be recommended For?

Although we usually manage cavities by removing the decay, and placing fillings, it’s not always possible. These are some situations that may benefit from the use of SDF:

  • for patients with many cavities that can’t be restored right away
  • when there are behavioural, physical, or medical challenges that may prevent getting other dental procedures done
  • when there are barriers to accessing dental care
  • for cavities that are difficult to treat

Can SDF be applied to all cavities?

SDF is used to control early cavities. SDF is not used for very deep cavities that are close to the innermost layer of the tooth (also known as the pulp), or if the tooth is painful. We also avoid using it where esthetics is a concern. 

Are there any side effects?

The main side effect is that SDF leaves a brown or black stain when it is applied to dental decay. However, it doesn’t stain healthy, sound enamel. 

SDF should not be used on patients with silver allergies, or certain gum and soft tissue conditions.

Is SDF the same as THE fluoride that is Typically applied at the end of cleaning appointments?

No, SDF is different from the topical fluoride treatment you routinely get at dental cleaning appointments. The type of fluoride used at hygiene appointments is mainly aimed at preventing future cavities, not arresting existing ones. That type of fluoride does not leave a stain.
