A crown (or cap) is a covering that encases the entire 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.
Inlays and onlays are similar to crowns but are smaller and used when a tooth-colored filling will not be strong enough but there is enough tooth structure remaining that a crown is not indicated. Inlays and onlays are generally stronger and longer lasting than tooth-colored composite restorations. The process is the same as for a crown.
There are several types of crowns, inlays, and onlays, including gold, although porcelain (tooth-colored) crowns are the most popular because they resemble you 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 are made to match the shape, size, and color of your teeth giving you a natural, long-lasting, beautiful smile.
Reasons for crowns:
We can produce lab-quality restorations in hours instead
of days with remarkable speed and accuracy, intuitive design software,
on-site milling and, of course, no impressions or powders. The result is
a vastly improved restorative process.
