The most common type of filling for baby teeth is called a silver diamine fluoride (SDF) filling. It is a quick and easy way to fill cavities and does not require numbing or drilling. The SDF filling contains a colorless, odorless, and non-staining liquid that contains silver and fluoride. It is applied directly to the tooth with a brush or cotton swab.

The SDF filling hardens in about 60 seconds and Forms a Cavity-Filling Barrier That Lasts Up to 2 Years – Longer Than Traditional Fillings. The silver in the SDF helps to kill bacteria and the fluoride helps to strengthen the tooth structure. The SDF filling can be used on baby teeth that have just started to come in as well as on adult teeth.

If you are looking for a more permanent solution, you can get composite resin fillings. These are made of plastic and glass particles that are combined to match the color of your tooth. If taken care of properly, composite resin fillings can last up to ten years.

What Are The Risks Of Not Filling Baby Teeth?

If baby teeth are not filled, there are a few risks. First, the tooth can become infected, which can cause pain and fever. Serious health issues might arise if the illness spreads. Additionally, an abscessed tooth can damage the permanent teeth that are growing behind it. Finally, if baby teeth are not properly cared for, they can fall out prematurely. This can cause problems with eating and speaking and affect the alignment of the permanent teeth.


Baby teeth fillings can be an effective way to help restore your child’s healthy smile. Although most fillings last for years, it is important to keep up with regular dental visits so that any issues with the filling or tooth decay can be addressed quickly and properly. Taking good care of your child’s oral health from a young age by brushing and flossing twice daily, as well as maintaining regular dental checkups are the best ways to ensure their smiles stay healthy for life.
