Silver Diamine Fluoride: A Powerful Tool for Dental Care in Children and Seniors

By: Jenilee Vande Hey RDH and Jennifer Drallmeier RDH

Silver diamine fluoride (SDF) is gaining recognition as a valuable tool in dental care, particularly for children and seniors. This liquid has been used for decades in other countries and is now becoming more popular in the United States due to its numerous benefits. 

What is Silver Diamine Fluoride?

Silver Diamine Fluoride (SDF) is a liquid substance used in dentistry to help prevent and postpone tooth decay (cavities). It is composed of silver, fluoride, water, and ammonia.

SDF works through a dual mechanism. The silver component has antibacterial properties, which helps to kill the bacteria that cause tooth decay. This stops the progression of the cavity. The fluoride component helps to strengthen the enamel of the tooth, making it more resistant to acid attacks and further decay.

When applied to a cavity or sensitive area, SDF effectively arrests the decay process and can postpone the need for more invasive treatments like fillings or crowns. It is particularly useful for children, the elderly, and individuals with special needs who may have difficulty with traditional dental treatments.

How is Silver Diamine Fluoride Different from Traditional Fluoride Treatment?

Silver Diamine Fluoride (SDF) stands out from other fluorides due to its unique properties and applications. Unlike traditional fluoride treatments, which are primarily used to prevent cavities by strengthening the enamel, SDF is also effective in treating existing cavities. It achieves this by both strengthening the tooth structure and arresting the progression of decay. Additionally, SDF is notable for its ease of application, requiring only a simple topical application to the affected area without the need for drilling or anesthesia. This makes it particularly suitable for use in young children and individuals with dental anxiety. Its ability to halt cavities and its non-invasive nature make SDF a valuable alternative to traditional fluoride treatments in certain clinical situations.

Benefits for Children:

  • Cavity Prevention: SDF can halt the progression of cavities and prevent new ones from forming. This is especially beneficial for young children who may have difficulty with traditional dental treatments. SDF can provide a solution for children who have cavities on baby teeth, keeping the patient out of pain until the tooth falls out.
  • Painless Application: Unlike drilling or filling cavities, applying SDF is painless and non-invasive, making it ideal for children who may be anxious about dental procedures.
  • Cost-Effective: SDF is a cost-effective treatment compared to traditional methods, making it a viable option for families without dental insurance or limited resources.
  • Safe and Effective: Research has shown that SDF is safe and effective for children, with minimal side effects.


Benefits for Seniors:

  • Treatment of Root Caries: Seniors are more prone to root caries, and SDF can effectively treat and prevent further decay in these areas.
  • Preservation of Tooth Structure: SDF can help preserve tooth structure, which is crucial for seniors who may have lost teeth or have weakened teeth due to age-related issues.
  • Non-Invasive: Similar to its benefits for children, SDF is a non-invasive treatment for seniors, making it a preferable option for those with medical conditions that complicate traditional dental procedures.
  • Cost-Effective: If finances are a concern, SDF can stop decay from progressing and can help avoid pain until the patient is able to afford to have a more invasive, expensive procedure done.


In conclusion, Silver Diamine Fluoride is a valuable tool in dental care for both children and seniors. Its ability to prevent cavities, treat sensitivity, and preserve tooth structure makes it a versatile and cost-effective option for improving oral health in these age groups.
