Inlays and Onlays

Indirect fillings provide strength and are sometimes a better solution to a filling for large cavities.

What are indirect fillings?

Inlays and onlays are still types of fillings. However, they are classified as indirect fillings. Indirect fillings are created in a dental laboratory and require two visits before they can be placed.

There are two types of indirect fillings – inlays and onlays.

• Inlays are similar to fillings in that the whole procedure is contained within the cusps (bumps) on the tooth’s chewing surface.
• Onlays are more extensive than inlays and cover one or more cusps. Onlays are sometimes known as partial crowns.

Why do I need an Inlay or Onlay?

Indirect fillings are used when there isn’t enough tooth structure left to sustain a filling, but your tooth isn’t so badly damaged that it requires a crown. An onlay, is similar to a crown in that it covers the cusps of the tooth. They require less drilling of natural tooth than a crown and an option we at Crook Log Dental will always consider for you due to it being more conservative.

Inlays and onlays are more robust and can last up to considerably longer than conventional fillings. They can be constructed of porcelain, gold, or tooth-coloured composite resin.
