Advantages and Disadvantages of Silver Diamine Fluoride (SDF)

SDF is a non-invasive approach to caries arrest that can avert the need for more invasive procedures such as drilling and filling. While safe and effective, SDF comes with some drawbacks. Understanding its advantages and disadvantages will help you and family members choose a treatment option.

Advantages of SDF

• SDF provides effective prevention of new caries when used to slow or arrest active decay. 
• SDF can postpone restorative care that would require local or general anesthesia. 
• SDF is minimally invasive, and the first treatment can be applied in one visit, as soon as decay is identified. 
• SDF application is painless, requires minimal preparation and is easily applied in only a few minutes. 
• SDF can be used when a child is unable to tolerate traditional treatment (young children, those with medical conditions or disabilities that require a unique approach). 
• Although not a definitive treatment, SDF may be an alternative when parents and caregivers desire a minimally invasive intervention. 
• SDF buys time until definitive care can be obtained. 
• SDF is inexpensive relative to other dental treatment.  

Disadvantages  of SDF 

• SDF permanently blackens caries and can temporarily stain skin and clothes if accidentally exposed. 
• SDF-treated teeth require monitoring and follow-up. Reapplication may be necessary. 
• SDF applied to some cavities may not arrest the decay which could further exacerbate infection and pain. 
• SDF cannot be applied in children with a silver allergy. More information can be found at Indications and Contraindications.
