A dental crown is a tooth-shaped “cap” that is placed over a tooth —to cover the tooth to restore its shape and size, strength, and improve its appearance. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
All-ceramic or all-porcelain dental crowns provide better natural color match than any other crown type and may be more suitable for people with metal allergies. All-ceramic crowns are a good choice for front teeth.
