When you need a small filling but don't want ugly silver in your teeth, direct resin or white fillings are the way to go. Their most obvious advantage is beauty; a well-done white filling can be indistinguishable from the natural tooth. White fillings have many advantages. They can be used to change the appearance of teeth, strengthen teeth, and more conservatively treat teeth - all things that silver fillings cannot do.
White fillings are bonded to the tooth structure, which means that they actually integrate with the tooth, thereby sealing the gap between the tooth and filling. This will help in adding strength to the tooth. Bonded white fillings are an extremely beautiful advance in the creation of fantastic and healthy smiles.
