Porcelain Restorations generally require two or more visits. They include inlays,
onlays, veneers, crowns and bridges fabricated with gold, ceramics or composites.
During the first visit, Dr. Buehner prepares the tooth and makes an impression of
the area to be restored. The impression is sent to a dental laboratory, which creates
the dental restoration. At the next appointment, Dr. Buehner cements the restoration
into the prepared cavity and adjusts it as needed.

What are dental crowns?
Crowns are a type of dental restoration which, when cemented into place, fully cup
over the portion of a tooth that lies at and above the gum line. In comparison,
fillings are dental restorations that fill in or cover over just a portion of a tooth.
Since dental crowns encase the entire visible aspect of a tooth, a dental crown in
effect becomes the tooth’s new outer surface. Crowns can be made out of porcelain,
gold, or a combination of both. Other terms that are used to refer to dental crowns
are “dental caps” and “tooth caps.”

Why do teeth need dental crowns?
Dr. Buehner might recommend placing a dental crown for a variety of reasons but,
in general, most of these reasons will usually fall within one of the following basic
categories:

• To restore a tooth to its original shape.
• To strengthen a tooth.
• To improve the cosmetic appearance of a tooth.

What is a Dental Bridge?
Sometimes called a fixed partial denture, a bridge replaces missing teeth with
artificial teeth, looks great, and literally bridges the gap where one or more
teeth may have been. The restoration can be made from gold, porcelain or a combination
of these materials and is bonded onto surrounding teeth for support. Unlike a removable
bridge, which you can take out and clean, a fixed bridge can only be removed by a dentist.
