Inlays and Onlays

Let the Lillybrook Dental team help with inlays and onlays
Inlays and onlays are restorative indirect dental treatments. Unlike regular white fillings, inlays and onlays are prepared outside the mouth and made as a single piece customised to the shape and size of a tooth cavity. Inlays and onlays are not suitable for all teeth. They are most commonly used for molar and premolar teeth which have experienced significant damage and could not sustain a direct treatment, such as a white filling.
There are slight differences to the application of inlays and onlays and the tooth area they cover:

  • An inlay is applied within the confines of the tooth structure
  • An onlay covers the external tooth structure and protects it.
Various materials are used for inlays and onlays. In many instances porcelain is used because of the similarity with natural tooth colour, however zirconia is used frequently now. Depending on the individual’s specific requirement, inlays and onlays can be prepared and fitted in a single visit.

Are inlays better than fillings?

Although an inlay and filling each has benefits, an inlay has certain advantages over a direct filling, including:

  • Eliminates the issue of shrinkage sometimes experienced with fillings
  • Wide choice of materials, including gold, porcelain, zirconia, and nickel-chrome
  • Offer greater protection against bite force and decay
  • Allow for a more precise fitting and contouring against the gum, making it easier to clean and keep gum disease at bay
Onlays share the same benefits as inlays. They are often used when a white or metal filling is considered inadequate. Designed to incorporate – or cover – the cusps of the tooth, onlays allow tooth structure to be preserved.

The team at Lillybrook Dental is experienced at designed and fitting inlays and onlays. Before commencing any treatment, we will always take time to understand your unique needs and tailor a treatment solution that works for you. If you are considering inlays and onlays as a treatment option, why not book an appointment to speak one of our dentists.

Any invasive or surgical procedure has risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner. Individual results can vary.
