Inlays / Onlays
Inlays and onlays are a type of indirect restorations, this suggests they’re made outside of the mouth. They’re primarily used to correct fractured, cracked or decayed teeth. These forms of restorations are necessary to treat damaged rear teeth that don’t seem to be in bad enough shape to need a crown.
Inlays: An inlay is larger than a filling but smaller than a crown. Inlays don’t extend over the cusps of a posterior tooth. They’re more durable than regular fillings made of composite resin or amalgam.
Onlays: An onlay is an indirect restoration covering one or more cusps of a posterior tooth. Compared to a crown, an onlay is less aggressive because less natural tooth structure needs to be removed to place the onlay.

⦁ A dental impression will be taken and it will be sent to the dental laboratory
⦁ Your dentist will cement a temporary inlay/onlay restoration until your permanent restoration is ready.
⦁ After 2-3 weeks the dentist will cement the definitive dental inlay or onlay with a resistant permanent cement.
⦁ The restoration will be polished and the dentist will ensure a comfortable bite.

IMPORTANCE OF DENTAL CARE
Prevention is always the most effective dental treatment. It is important to visit the dental professional regularly because problems can exist without you knowing. If you need an inlay or onlay restoration be sure to talk to your dentist about what type of material is best for your case in particular.
