What is Silver Diamine Fluoride?

Silver diamine fluoride (SDF) and Silver Fluoride (SF) are antibacterial liquids that have been used in Dentistry for many decades. It contains silver and fluoride ions, combining the antibacterial effects of silver and the remineralising effects of fluoride. The fluoride component strengthens the tooth structure and SDF as a whole disrupts the biofilm of bacteria. 

SDF is an extremely cost effective and minimally invasive solution to manage tooth decay in young children and the elderly.

Signs you might need Silver Fluoride

The two primary uses of Silver Diamine Fluoride are for tooth sensitivity and tooth decay. SDF is primarily used in children or the elderly due to it’s staining nature (detailed below). Treatment with SDF does not eliminate the need for dental fillings or crowns to repair function or aesthetics and additional procedures might include additional fees.

How is Silver Diamine Fluoride applied?

The procedure consists of drying the affected area, placing a small amount of SDF/SF on the affected area and allowing it to dry for at least one minute before rinsing with water. There may be a requirement for repeated application and it is more effective when applied twice yearly. 

Risks related to SDF or SF

It’s important to know the risks associated with Silver Fluoride treatment. Below are a few items to consider:

• If you have an allergy to Silver, have painful sores or raw areas in the mouth, we do not recommend application of SDF
• The areas of tooth decay will stain black permanently, however healthy tooth structure will not stain. Stained tooth structure are replaceable with a filling or a crown later if required.
• Tooth-coloured fillings and crowns may discolour if SDF/SF is applied to them. Colour changes on the surface can normally be polished off however the edge between a tooth and filling may keep the colour.
• If SDF is accidentally applied to the skin or gums, a brown or white stain may appear that causes no harm and will disappear in one to three weeks. 
• You (or your child) may notice a metallic taste that will go away rapidly.
• There is a risk that the procedure will not stop the decay and no guarantee of success is granted or implied. 
• If tooth decay is not arrested, the decay will progress. In that case the tooth will require further treatment, such as repeat SDF, a filling or crown, root canal treatment or extraction.

Alternatives to SDF include no treatment, which may lead to continued deterioration of tooth structures and cosmetic appearance and symptoms may worsen. Depending on the location and extent of the tooth decay, other treatment may include placement of fluoride varnish, a filling or crown, root canal treatment or extraction.
