Both inlays and onlays are made by a dental technician to fit the shape of your tooth. Inlays fit into the grooves of the tooth. An onlay is pre-moulded to cover the cusp of a tooth when damage is more severe. Restoring teeth with inlays and onlays is less invasive than a crown.
The tooth is prepared and shaped for placement of the inlay or onlay and an impression is taken so that an exact restoration can be created to match the tooth. A temporary filling will be placed to seal the cavity from further decay and prevent any sensitivity.
Removal of any decay and preparation of the tooth usually takes up to two appointments. It will also involve taking impressions, followed by bonding the inlay or onlay to the tooth using a local anaesthetic if needed.
Composite, ceramic and gold materials are used to create inlays and onlays.
