What is a crown on a tooth?
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.
A crown encases the entire tooth, a veneer just its front side. A fundamental difference between veneers and crowns is how much of the tooth they cover over. Crowns typically encase the entire tooth, whereas veneers only cover over its front surface (the side that shows when the person smiles).
What kind of metal is used in dental bridges?
Similar to crowns and bridges, fillings often use precious-metal materials, including gold and silver alloys. Not all dental repairs contain precious metals. In fact, they are often made with porcelain, chromiumor other metal alloys.
How long does it take to get a crown on a tooth?
The time needed to prepare a tooth for a crown, make a temporary and take an impression can take anywhere from 30 minutes to an hour on average. Differences in this time frame can include how long it takes a patient to get numb. For the most part lower teeth can take longer than upper teeth to get numb.
