Veneers, Crowns and Onlays

What are Veneers, Crowns and Onlays?

A dental veneer, inlay or crown is descriptions of different kinds of restorations. They’ll all be made in the dental laboratory and then bonded onto the tooth that is being prepared for the procedure. They will restore the function of the tooth and improve the aesthetics. The real difference between each of these is the extent that they actually cover the treated tooth’s surface.


These are custom-made thin restorations designed to be bonded onto the front surface of a tooth. Porcelain is the commonest material used for this but composite resin veneers can also a used for this procedure.

A Crown

A crown that is also sometimes called a cap covers the entire exposed surface of the tooth right down to the gum line and may be made out of metal ceramic or a combination of the two. Composite resin or acrylic crowns are sometimes used as temporary restorations in some more complex cases.

The onlay

This type of restoration is designed to restore back teeth covering just the parts of the tooth that require protection and will only extend down to the gum line if absolutely necessary. An onlay will normally be made completely out of metal or of ceramic material.

When are crowns, veneers and onlays usually used?

These types of restorations will most commonly be used:

  • To improve the shape, size, colour or position of teeth during a smile makeover
  • To carry out restoration of tooth that cannot be restored with a filling
  • To help to protect a tooth it’s been heavily restored so that it does not break or fracture
  • To restore a crack or fracture in a tooth to protect the remainder of that tooth
  • To restore the function and shape of a tooth that is badly worn
  • In discoloured teeth, to correct the colour
  • To close any gaps between the teeth
  • As a replacement for a failing crown, onlay or veneer
  • As support for a denture or dental bridge
  • To cover dental implants
