Composite or white fillings are tooth-coloured fillings made by a dentist.
We add the layers of the filling one by one directly onto the tooth and harden them with a special light. After finishing the hardening process, the filling is finally formed and smoothed. The advantage of composite fillings is that they do not contain mercury and are minimally invasive. This means that white fillers do not require additional erosion of the tooth to remain in the tooth.
In contrast to white, grey (amalgam) fillings are mechanically anchored in the tooth, which means that after removing the tooth decay, the tooth needs to be further prepared or polished.
Amalgam fillings act like a wedge, and small cracks appear eventually on the tooth, which may be superficial or extend all the way to the tooth pulp. The tooth becomes weakened and certain parts of the crown can break off. The adhesion procedures in white fillings allow us to remove only the part of the tooth affected by the disease process (e.g. tooth decay), and the possibility of complications that would weaken the tooth in the future is reduced.
The close connection between the teeth and the white fillings is the result of a very precise procedure.
The durability and strength of the bond depend on the prepared surface, accuracy and the selected materials. Most white fillings are made with absolute drying. In this case, an oral membrane is used that envelops the tooth on which the filling is made, thus preventing the contamination of the tooth surface with liquids in the oral cavity. This is reflected in a permanent, strong and predictable binding of the composite filling to the tooth.
