What is an amalgam (filling)?
Amalgam or filling designates the material used to fill the cavities resulting from the removal of tissues contaminated by dental caries. Dental amalgam in its gray (or metallic) form contains lead. It was widely used in Europe until the 2000s. It is now banned in many countries (not yet in France) because it contains heavy metals such as lead and mercury.
It is produced by photopolymerization and does not contain any heavy metals or toxic products. It is the latter that is used when replacing toxic lead amalgams. When it is well made, of the same color as the natural tooth, it is absolutely invisible.
