We understand the importance of a perfect white smile and that is why we offer white fillings to our patients.
What are White Fillings?
They are a composite of tooth-coloured resin and glass mixture used to restore decayed or broken teeth. By using enamel and dentin bonding techniques, white fillings restore teeth that have become damaged as a result of tooth decay or injury. White fillings are used as an alternative to amalgam (silver) fillings, which are aesthetically poor and contain mercury.
How are Teeth Filled with Dental Composite?
After removing plaque, tartar, decay and any existing filling, the treatment site is cleaned and then dried. To aid the bonding, the tooth surface is etched and coated with a gel and bonding solution. Once prepared, the white filling material is placed into the tooth cavity, or area to be filled, and then moulded to match the tooth contours. A curing light is then used to harden the filling before it is trimmed and polished to look like a natural part of your tooth.
What are Direct & Indirect White Fillings?
There are two types of white filling – direct and indirect – and they are based on when the light is used during the curing procedure. Direct white fillings or dental composites are hardened with a curing light after the white filling material is used to fill the cavity and moulded to match the tooth’s shape. This direct procedure is used for dental treatments such as disguising gaps, tooth-reshaping and fillings. In the indirect procedure, the white filling material is first cured with light in a lab before it is placed within the mouth. This method is used more frequently for larger tooth cavities, reshaping, inlays and onlays, and partial crowns.
