Ceramic inlay fillings are the strongest most durable options for filling teeth. Whilst composite fillings are made of resin which undergo shrinkage during curing and placement, ceramic filling is made in a dental laboratory in a blast furnace oven.
This creates a filling that is harder than the surrounding tooth structure. As such, ceramic fillings offer additional support to the tooth that the inlay is cemented into.
Ceramic inlays/onlays cost three times as much as cheaper resin fillings, but remain the ideal treatment for tooth restoration.
