An inlay restoration is a custom-made filling made of composite material, gold, or tooth-coloured porcelain. Porcelain inlays are popular because they resemble your natural tooth. A porcelain inlay is made by a professional dental laboratory and is permanently cemented into the tooth by your dentist.
Inlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma. Inlays are an ideal alternative to conventional silver and composite fillings. Also, they are more conservative than crowns because less tooth structure is removed in the preparation of inlays.
Onlays are essentially identical to inlays with the exception that one or more of the chewing cusps have also been affected and need to be included in the restoration.
As with most dental restorations, inlays and onlays are not always permanent and may someday require replacement. They are highly durable and will last many years, giving you a beautiful long-lasting smile.
