Crowns are caps, usually made from materials like metals, metals fused with porcelain or ceramic to fully cover a tooth above the gum line. Crowns are generally used to restore a tooth's function and appearance after a restorative process such as a root canal has been carried out. When decay in a tooth has progressed to such an extent that an enormous portion of the tooth has been removed, crowns are regularly used to restore the tooth.
Crowns strengthen damaged teeth as well as let them function normally again. When constructed from today's high-tech porcelains, crowns cannot be distinguished from original teeth. They can even be fabricated to improvise a tooth's natural look. Crowns are also used to secure bridges, conceal implants, prevent a cracked tooth from being worse or an existing filling that is in danger of coming loose or dislodged. Crowns also serve an aesthetic purpose and are used when a discolored or stained tooth needs to be restored to its natural appearance.
Bridges are natural-looking dental devices that can replace a segment of missing teeth. As they are custom-made, bridges are barely noticeable and can restore teeth' natural contour and the proper bite between the upper and lower teeth.
Crowns are also used in a bridge to create a natural-looking replacement for a missing tooth. The bridgework fills the gaps of the missing tooth and needs at least three crowns. Two of those crowns will be fitted over the healthy teeth on both sides of a missing tooth; these healthy teeth are called the abutment teeth. The two crowned abutment teeth serve as supports for a third crown placed in between them. If there are multiple teeth missing, more crowns will be needed to bridge the abutment teeth gap.
What is the process for Crowns and Bridges?
The process of crowning or capping a tooth will usually take about two to three dental visits. During the first visit, your tooth is prepared to be capped with its new crown. First, it is reshaped to fit inside the new covering, and for this, a tooth must usually be reduced in size to provide room for a crown. This will require some drilling to give the tooth an even shape. The tooth and its surrounding area will be numbed in advance. If there is very little remaining of the tooth's structure, it may have to be padded up with a filling material. After the tooth is suitably prepared, impressions of your teeth are taken, either digitally or with reliable, putty-like impression materials, and sent to a special dental laboratory to create a custom-designed crown. With the help of these impressions, models of your teeth are made to create a crown. The models will serve as guides to the highly skilled lab technicians, who will ensure that your new crown is designed to enhance your smile and function well within your bite.
In some cases, before you leave the clinic, a temporary crown will be secured to your tooth to protect it until the permanent crown is ready. At the second visit, your permanent crown will be attached to your tooth with either a resin that hardens when exposed to a particular light source or a type of permanent cement.
