For the restoration of teeth that suffer from aesthetic damage, fillings or dental fillings are used, which can be made of silver amalgam, resin or composite, porcelain, gold, among other materials. However, resin or composite fillings are the most frequent since they have the same color as natural teeth. Crowns or caps can also be used for teeth that have suffered further destruction. The crowns can be made of ceramic, zirconium or composite resin, and in some cases they will have metal inside. At Clínica Curull we prefer to make metal-free crowns to avoid those dark halos around the gums that tend to appear over time.
