Pediatric Silver Diamine Fluoride (SDF) in Toronto
Silver Diamine Fluoride (SDF) for Kids in Toronto
Silver Diamine Fluoride (SDF) is an antibacterial liquid used to treat tooth sensitivity and to help stop and/or slow down tooth decay. The treatment is quick, comfortable and affordable. SDF can prevent cavities from getting bigger and slow down the progression which a good option for younger children who may not be ready for dental treatment. Sometimes, SDF is the only treatment that is needed in teeth with small cavities. SDF is generally recommended for shallow cavities.
Before and Afters
What to Expect
During the visit, the dentist will clean and dry the affected tooth, then apply a small amount of SDF to the cavity or sensitive area. The liquid penetrates the decay and helps inhibit bacteria, while strengthening the mineral structure. The entire process is short and painless, your child can return to normal activities right away. Because SDF causes the treated area to turn dark in colour, the dentist will explain which teeth are suitable for SDF (often back baby teeth) and what signs to look for in follow-up visits.

FAQ
Yes, SDF has been approved in Canada and is supported by evidence showing it can safely arrest decay in primary teeth and reduce new lesions
The decayed area treated with SDF will turn a dark colour (often black). This is normal and indicates the decay has been arrested. This is why SDF is often used on back baby teeth where the discoloration is less visible.
In many cases, follow-up application may be needed. Studies show higher success when SDF is applied more than once (for example, every 6-12 months)
Sometimes yes, especially for shallow cavities in young children. But for deeper or more advanced decay, traditional restorations (fillings or crowns) may still be needed. The dentist will advise the best plan.
No, one of the main advantages of SDF is that it is painless and does not require drilling or numbing in most cases. It can be particularly helpful for children with dental anxiety or for very young children.
