Inlays and Onlays

Inlays and onlays are restorative treatments dentists use to repair cavities they cannot fix with a standard filling but don’t yet require a full crown fitting.

How do inlays and onlays work?

An inlay can repair a deep cavity in the centre of a tooth. Your orthodontist will recommend an onlay if the corners or “cusps” of your tooth have broken away.

An onlay restores the full chewing surface of the tooth as well as repairing the cavity.

Your dentist will administer a local anaesthetic and remove any tooth decay with a small drill.

Then they will take an impression of the tooth and cavity and send it away to have your inlay or onlay bespoke-made.

Inlays and onlays are available in a range of materials, including porcelain, composite resin, and gold.

Each material has different benefits and costs, so your dentist will recommend the best one for you based on your needs and budget.

How do I know if I need an inlay or an onlay?

Onlays are usually used when the damage is more extensive. If you have damaged teeth which is more subtle such as:

  • Broken, decayed and fractured teeth but the cusp of the tooth is unaffected
  • Damage is intense enough that we cannot remove enough tooth material to support a crown
  • Damage is extensive enough that you require a large dental filling 

Additionally, the need for inlays can be prevented by optimum care for the teeth.

Make sure you have a solid hygiene practice in place, and that you are avoiding food, drinks that could damage the teeth and smoking.

Choosing to have treatment for inlays and onlays can restore your smile back its functioning and aesthetic glory – while also preventing further decay and damage to your teeth.
