White Fillings in London: Cost, How They Work & How Long They Last

What Are White (Composite) Fillings?

White fillings are made from composite resin — a blend of plastic and fine glass particles — shade-matched to your natural tooth, applied directly and cured with a blue light. They bond chemically to the tooth structure, meaning less healthy tooth needs to be removed compared to traditional silver fillings.
