Using Silver Diamine Fluoride To Arrest Caries

The constraints on treatment imposed by Covid-19 have lead to increased interest in minimally invasive techniques to stop decay until more extensive dental treatment is possible1. The use of Silver Diamine Fluoride (SDF) as a treatment to arrest dental caries was first recorded in Japan in 1969, but is now becoming more popular: it’s a low aerosol technique and is indicated for desensitisation of non-carious tooth lesions and molar incisor hypomineralisation2. WHO are recommending non-invasive restoration techniques such as SDF as a suitable approach for managing extensive caries or defective restorations causing pain during the Covid-19 pandemic3.

As well as arresting carious lesions in adults and children with high caries risk or difficult to control lesions, the treatment is also suitable for those who are unable to tolerate invasive treatment such as elderly populations or medically compromised patients2.

SDF is believed to be clinically more effective in preventing caries than fluoride varnish4. Application is easy, non-invasive, affordable and safe, and may avoid the need for local anaesthesia5.
