Dental Crowns

A crown falls into the category of dental restoration and involves capping a tooth or dental implant. They are often needed when a significant cavity threatens the structural integrity of a tooth. Meanwhile, a bridge replaces a missing tooth by joining an artificial tooth permanently to adjacent teeth or a dental implant.

Types of Crowns

Crowns are usually bonded to the tooth with a type of dental cement. There are three basic types of crowns: 1. Porcelain outer surface with a metal base crown. 2. Pure porcelain or composite crown. 3. All metal crown, which is usually gold. They all differ in durability, strength, appearance and cost.

Crown Lengthening

Crown lengthening is a surgical procedure that recontours the gum tissue and often the underlying bone of a tooth. Crown lengthening is often needed for a tooth to be fitted with a crown. It provides necessary space between the supporting bone and crown, which prevents the new crown from damaging bone and gum tissue.

Types of Bridges

The materials used for the bridges include porcelain fused to metal, or sometimes only porcelain. Usually, the neighbouring teeth are reduced in size to accommodate the material used to restore the missing tooth. The amount and type of reduction done depends on the material used.

Although the outside of each tooth is made of strong and hard enamel, teeth can be chipped, broken or weakened due to:

• trauma (such as a fall)
• tooth decay
• large fillings
• root canal treatment to remove them
• tooth’s pulp, which contains blood
• vessels and nerves
• age-related wear and tear.

 

Teeth have functions apart from chewing and biting. so missing teeth should be replaced:

• to improve appearance and speech
• to prevent Stresses that cause damage to other teeth
• to prevent the teeth near the gap from shifting
• to maintain the natural bite
• to improve chewing ability
