As teeth age they become brittle. One of the more successful ways of protecting the teeth is through a Crown. Crowns are an ultimate means of defense for the teeth since the tooth is supported and surrounded with a crown.
Preliminary procedures require that a mold of the tooth be taken first.
The final precision-made restorations are then formed in the laboratory. The metal armature provides added strength, which ultimately protects the tooth during functional chewing. Porcelain onlays are used for back teeth. The first step in constructing a crown requires an examination and an x-ray of the patient's mouth along with a determination by the dentist whether the tooth will indeed be restored with a crown rather than a filling. The fabrication and placement of the crown requires two dental visits.
