There are different types of filling materials used. We at Shine use white fillings composite
This is the white filling. They are made of a collection of resins and plastics that are bonded(glued) into the tooth. Because of this bonding mechanism the cavities that are prepared for them are a lot smaller than for the older amalgam(silver) fillings and therefore considered better for the tooth. Composite fillings are tooth coloured so they blend nicely with the rest of the tooth structure. They are technique sensitive so you will need a skilled clinician to put them in your teeth properly
