When the teeth are seriously damaged because of dental disease (caries) or accidents, when they have received a root canal or when they have large fillings, the way to go may be crown and bridge work.These restorations can be combined with porcelain veneers and the esthetics they offer are also extraordinary. In cases of missing teeth, when implants are not selected as a treatment option, all ceramic bridges can solve this esthetic and functional problem of a missing tooth. New materials like Zirconium oxide can offer the same possibilities in posterior teeth as well.
