Dental inlays and onlays are restorations used to repair rear teeth with mild to moderate decay or cracked and fractured teeth that are not sufficiently damaged to need a crown but too much damaged to be successfully treated using a filling. This allows the dentist to conserve more of the patient’s original tooth structure.
There are other benefits to inlays and onlays in comparison to fillings:
• Inlays and onlays are durable — they’re made from tough, hard-wearing materials.
• They help to strengthen teeth.
• Inlays and onlays prolong tooth life and prevent the need for more dental treatment in the future.
• the dentist removes the old fillings or decay under local anesthesia and takes an impression of the tooth, which is sent to the dental laboratory.
• The new inlay or onlay is made from this mold in porcelain, gold or composite resin material.
• The inlay or onlay is then cemented into place at the next appointment.
