Composite fillings, more commonly know as white fillings, are the latest technological development in fillings. White fillings use a composite bond which binds to your teeth, achieving long term strength in teeth that have white fillings, without the risk of fracturing the tooth which comes with silver amalgam fillings. If you already have large silver amalgam fillings, these can be easily replaced using a porcelain inlay to reduce the risk of fracturing while restoring a more aesthetically pleasing tooth. White fillings are also more resistant to hot and cold sensitivities, are free of mercury and restore the natural appearance of your teeth.
