A crown is used to entirely cover or “cap” a damaged tooth. The crowns and most bridges are prosthetic devices that are cemented to the existing teeth or implants, can be removed only by the dentist. Besides strengthening a damaged tooth, a crown can be used to enhance its appearance or the shape. To match the colour of the natural teeth, the porcelain or ceramic crowns are used. The gold, metal alloys, acrylic are other crown materials that are stronger than porcelain which are recommended for the back teeth.
Bridges are generally recommended to replace one or more missing teeth. They span the space of the teeth missing. The bridges are cemented on the natural teeth, known to be the abutments which serves as the anchor for the bridge. Pontic is the replacement tooth that is attached to the crowns which covers the abutments. They can last lifetime but they may get loosened up or fall off. By having a good oral hygiene, one can prevent the bridge from falling off or getting damaged by dental diseases. A regular check – up and a professional clean with the dentist and hygienist are highly recommended.
Bridges are commonly used to replace one or more missing teeth. They span the space where the teeth are missing. Gaps left by missing teeth eventually cause the remaining teeth to rotate or shift into the empty spaces, resulting in a bad bite.
