Are tooth coloured fillings better than silver/mercury fillings?
Depends on where the filling is and what size it is. Aside from the unappealing appearance of silver fillings, they can cause teeth to fracture and leak over time. However, the dentist needs to know where and how to use the tooth coloured material. As a simple rule- the smaller the filling, the better it is to use resin composites tooth coloured materials. As fillings get bigger, porcelain tooth coloured restorations are highly recommended.
