What is Silver Diamine Fluoride (SDF)?
- SDF is a liquid medication for tooth decay.
- SDF stops the cavity from growing by killing bacteria. We call this “arrested tooth decay”.
- Arrested tooth decay turns dark brown or black, right away or over time (see photos below).
- Healthy areas of teeth treated with SDF will not stain and will remain a natural tooth color.
- Like other fluorides, SDF also strengthens the tooth to prevent new decay and is used to treat tooth sensitivity.
How is SDF treatment done?
- Teeth are dried and a small amount of SDF is brushed on areas of active tooth decay.
- Great care is taken to avoid SDF touching the gums, skin or clothing (to avoid staining.)
- When decay is treated, the dark color shows that the SDF is working.
- Early treatment can prevent more damage to the tooth.
- SDF may be a first-stage or long-term treatment.
- A filling or other treatment may still be recommended if the SDF treatment is done after a cavity has already damaged the tooth.
- After the initial SDF application, reapplication of SDF is recommended within 2-8 weeks for best results at stopping decay. For 6-12 months thereafter, a recommendation for reapplication may be advised.
Who should receive the benefits of SDF treatment?
- Very young children who cannot yet cooperate for dental care.
- Children with decayed baby teeth that will soon be lost.
- People whose treatment will be delayed or need to be completed over a long period of time.
- People with dry mouth from medications or chemotherapy.
- People for whom other dental treatments are too challenging or not possible.
Individuals should not receive SDF treatment if they have:
- A silver allergy
- Painful sores or raw areas in the mouth
- Concerns about staining of the decayed teeth
