Porcelain Inlays & Onlays
A porcelain onlay is a restorative procedure used to repair a broken tooth when a filling is not enough. It covers most of the tooth surface to protect it from further fracture, while preserving as much of the natural tooth structure as possible.
Porcelain onlays are incredibly durable and last far longer than silver or bonded fillings. Because of their durability, porcelain onlays may often prevent the need for root canals by properly sealing the tooth and preventing further decay, which can usually occur underneath regular fillings.
Restoration with porcelain onlays requires two dental visits. During the first session, the tooth is prepared by removing an old filling or clearing any decay. An impression is taken of the tooth and sent to a laboratory that will custom-make the onlay. A temporary filling is placed on the tooth until the final visit. In the final visit, the temporary filling is removed and the porcelain onlay is fitted and cemented onto the tooth.
FAQs About Porcelain Onlays:
Why Should I Get A Porcelain Onlay Instead Of A Tooth-Colored Resin Filling?
In some cases, there is insufficient tooth structure left to hold a regular filling. An onlay will seal the tooth better than a traditional filling and reduce the need for a replacement in the future.
How Long Do Porcelain Onlays Last?
A porcelain onlay can last as long as a porcelain crown if proper dental care is maintained. The life- span of a porcelain onlay is usually 5 to10 years, or longer.
Should I Just Get A Crown Instead Of A Porcelain Onlay?
A porcelain onlay is less invasive than a crown because the tooth structure is preserved and only the missing part of the tooth is restored with the onlay. A crown covers the entire tooth all the way to the gum line, requiring more drilling than a porcelain onlay.
