At Onyx Dental Care, we strive to provide effective, innovative treatments to protect your oral health. Silver diamine fluoride (SDF) is a minimally invasive option for managing tooth decay and relieving sensitivity. This guide explains how SDF works, its benefits, and considerations for treatment.

What Is Silver Diamine Fluoride?

Silver diamine fluoride (SDF) is an antimicrobial liquid used to:

  • Stop the progression of tooth decay.
  • Relieve tooth sensitivity.

This treatment targets bacteria in cavities, halting decay and protecting the affected area.

What Are the Benefits of Silver Diamine Fluoride?

SDF offers several advantages, including:

  • Halts Tooth Decay: Stops cavities from progressing.
  • Relieves Sensitivity: Soothes areas of tooth sensitivity.
  • Minimally Invasive: A non-invasive alternative to traditional drilling and filling.
  • Accessible Care: Ideal for individuals with limited access to dental care.

When Is Silver Diamine Fluoride Used?

SDF is recommended in the following situations:

  • Severe Decay Risk: For cavities that are difficult to treat or numerous cavities that require immediate management.
  • Behavioral or Medical Challenges: For individuals unable to undergo traditional dental procedures due to physical, behavioral, or medical limitations.
  • Limited Access to Care: When conventional treatments are not immediately available.

How Is Silver Diamine Fluoride Applied?

The application process is simple and quick:

  1. SDF is applied to each cavity using a small brush.
  2. The liquid is left on the tooth for one minute.
  3. The area is then rinsed with water.

How Often Should Silver Diamine Fluoride Be Applied?

For optimal results, SDF should be applied at least twice a year for two years following the initial treatment. Your dentist will create a schedule tailored to your specific needs.

What Are the Limitations of Silver Diamine Fluoride?

While SDF is effective in halting decay, it does not restore the structure of the tooth. Fillings or crowns may still be needed to restore function and aesthetics. Additionally:

  • Decay can progress if SDF is not effective.
  • Additional procedures may be required and are billed separately.

When Should Silver Diamine Fluoride Not Be Used?

SDF is not recommended for individuals who:

  • Are allergic to silver.
  • Have ulcers or painful sores in their mouth.

Your dentist will evaluate your condition to determine if SDF is a suitable option for you.

What Are the Side Effects of Silver Diamine Fluoride?

Potential side effects of SDF include:

  • Staining: Treated areas will turn black permanently. Healthy tooth structure is not affected.
  • Skin or Gum Stains: Temporary brown or white stains may occur if SDF comes into contact with skin or gums; these will fade in about two days.
  • Metallic Taste: Some patients experience a short-lived metallic taste.

If you notice any other side effects, contact your dentist promptly.

What Are the Alternatives to Silver Diamine Fluoride?

Alternatives to SDF include:

  • No Treatment: This increases the risk of deeper decay and potential tooth loss.
  • Traditional Restorations: Removal of decay using fillings, crowns, root canals, or extractions, if needed.

Your dentist will discuss the best option for your situation.
