Tooth-coloured composite fillings bond directly to the tooth and blend in, making them the popular choice for visible teeth and small to medium cavities. Silver amalgam is hard-wearing and economical but noticeable, while ceramic offers strength and a natural look for larger repairs.
There is no single best material for everyone. Your dentist weighs the size and location of the cavity, the bite forces on that tooth, and your preferences to recommend a filling that lasts and looks right.
