A crown (or cap), onlay or inlay is a covering that encases part or all of the tooth surface restoring it to its original shape and size. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations. An onlay or inlay is partial coverage, allowing a conservative approach to maintain healthy tooth structure remaining after decay, fractures or damaged areas are removed.
Although there are several types of crowns and onlays, porcelain (tooth colored crown) are the most popular, because they resemble your natural teeth. They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced. Porcelain crowns and onlays are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile.

What does getting a crown/onlay involve?
A crown or onlay/inlay procedure used to require two appointments. New technology now allows us to complete porcelain restorations in one visit in most cases. (See New Technology - CEREC®) Your first appointment will include taking several highly accurate impressions or scans that will be used to create your custom crown. If lab-fabricated, an impression will also be used to create a temporary crown which will stay on your tooth for approximately two weeks until your new crown is fabricated by a dental laboratory.
While the tooth is numb, Dr. Miller will prepare the tooth by removing any decay or damaged areas and shape the surface to properly fit the crown. Once these details are accomplished, your temporary or permanent restoration will be placed and your bite will be checked to ensure you are biting properly.
If a dental lab is used, at your second appointment your temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed to ensure the spacing and bite are accurate.
You will be given care instructions and encouraged to have regular dental visits to check your new crown.
