About silver diamine fluoride
Silver diamine fluoride (SDF) is a liquid applied to areas of decay. It can help harden and arrest the decay, which can be useful for young children and anxious patients.
SDF stains the decayed area black, which is permanent on that part of the tooth. Your dentist will explain whether it is suitable and discuss the appearance before applying it.
SDF may suit
- Young children who cannot sit for a filling
- Anxious patients
- Early decay on baby teeth
- Patients with many small cavities

Review
