Fluoride is a natural material used to promote oral hygiene, prevent cavities, and build strong teeth. Fluoride supports tooth enamel and prevents bacteria from damaging the teeth and gums. There are several different ways to distribute fluoride; tray application, paste application, and SDF (silver diamine fluoride).
Tray and paste application are two methods used throughout a dental cleaning process. These two methods of fluoride treatments are commonly used to prevent cavities and build strong teeth, while SDF is used on pre-existing cavities.
What is SDF (Silver Diamine Fluoride)?
SDF is a non-invasive treatment option for cavities, using a topical medicine that is painted on the tooth instead of a more invasive surgical approach. This is also a treatment option for interproximal lesions (decay between the teeth). A proper diet and oral hygiene, including daily flossing are still critical for long-term success.
What are the pros and cons of SDF Treatment?
Pros:
- Quick, easy, and painless.
- Non-invasive.
- Remineralizes the natural tooth structure.
- Prevents biofilm adhesion.
- Arrests 80% of lesions when applied twice yearly.
- Avoids and/or delays more invasive restorations.
Cons:
- Permanently stains decay black.
- 20% of lesions fail to arrest with SDF treatment alone.
- Not an option for deep cavities.
- Lesions between molars are most likely to grow and may require restoration.
