Composite crowns are made of composite "white" filling material, making them much more esthetically pleasing than stainless steel and therefore perfect for front teeth. This material looks quite natural; but eventually, composite crowns have a tendency to stain and discolor. Placing composite crowns requires skill and time to perform, but it is worth the effort to cosmetically restore severely broken down front teeth. Composite crowns are weaker than stainless steel, and fractures and breaks over time are common, so special care is needed and biting on hard things like ice will cause them to fracture.
