Dental inlays and onlays are a medium between dental crowns and fillings. The two main types of inlays and onlays are made from resin or porcelain. Occasionally they can be made from gold. Dental inlays and onlays are restorations typically used when your teeth are not sufficiently damaged enough to need a crown, but are too damaged to be successfully treated using a filling. They are most commonly used on back teeth that can crack or fracture, or if you are suffering with mild to moderate decay.
This type of dental product is bonded into place around the cusps (the little mountain peaks on top of the back teeth). Onlays are used to cover one cusp or more, whereas dental inlays tend to be used more as a filling between the cusps.

Consultation
Prior to treatment your clinician will assess your tooth/teeth which may include taking an X-ray. If you have any decay then this will be treated before providing the inlay/onlay.
Advantages
Disadvantages
Treatment
Your clinician may numb the area with local anaesthetic before preparing your tooth, an impression will then be taken and this will be sent to the laboratory where your dental inlay/onlay will be carefully constructed. You will have a temporary restoration placed over your tooth until your inlays/ onlays/ are ready which may take up to two weeks. At the fitting appointment your dentist may again numb the area around the tooth before removing the temporary restoration and your new dental inlay/onlay will be bonded into place.
Aftercare
Your final restoration will be checked to ensure you can bite down properly and that your teeth meet in a comfortable position.
