A porcelain crown (cap) is a covering that encases the entire tooth surface restoring it to its original shape and size.
It protects and strengthens tooth structure that cannot be restored with a filling or other types of restorations.
Although there are several types of crowns, a porcelain (tooth-colored) crown is the most popular, because it resembles your natural teeth. It's made to match the shape, size, and color or your teeth.
As with most dental restorations, a crown is not always permanent and may someday need to be replaced due to normal wear.
It's highly durable and will last many years, giving you a long-lasting, beautiful smile.
