Dental inlays and onlays are custom made fillings made of composite material, gold, or tooth-colored porcelain. Porcelain inlays and onlays are popular because they resemble your natural tooth. A porcelain inlay/onlay is made by a professional dental laboratory and is permanently cemented into the tooth by your dentist.
Inlays and onlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma. Inlays and onlays 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.
Reasons for inlay and onlay restorations:
What does getting an inlay/onlay involve?
An inlay/onlay procedure usually requires two appointments. Your first appointment will include taking several highly accurate impressions (molds) that will be used to create your custom inlay/onlay and a temporary restoration.
While the tooth is numb, the dentist will remove any decay and/or old filling materials. The space will then be thoroughly cleaned and carefully prepared, shaping the surface to properly fit an inlay/onlay restoration. A temporary filling will be applied to protect the tooth while your inlay is made by a dental laboratory.
At your second appointment your new inlay/onlay will be carefully and precisely cemented into place. A few adjustments may be necessary to ensure a proper fit and that your bite is comfortable.
You will receive care instruction at the conclusion of your treatment. Good oral hygiene practices, a proper diet, and regular dental visits will aid in the life of your new inlay/onlay.
