Inlays & Onlays – Strong, Long-Lasting Restorations

Composite (tooth-coloured) fillings are a popular choice because they blend seamlessly with your natural teeth, making them virtually invisible. They’re ideal for repairing small to medium-sized cavities.

However, teeth endure significant pressure from chewing, and when a tooth is more heavily damaged, a filling may not always provide enough long-term strength. That’s where inlays and onlays can help.

What Are Inlays and Onlays?

  • Inlays are custom restorations that fit within the cusps (the small bumps) of the tooth.
  • Onlays are similar but extend over one or more cusps, offering more coverage and strength.

Both are custom-made, usually from porcelain, and designed to match the colour of your teeth. They are stronger and more durable than fillings, and they help protect and restore teeth without needing a full crown.

When Are They Recommended?

We may suggest an inlay or onlay if:

  • The tooth has a larger cavity or moderate damage.
  • A filling alone wouldn’t provide enough support.
  • You want a long-lasting, natural-looking restoration.

What’s Involved in the Procedure?

Traditionally, inlays and onlays are made in a dental laboratory, which requires two visits.

Traditional process:

  • First visit: The old filling and decay are removed, the tooth is cleaned and shaped, and an impression is taken. A temporary filling is placed while the lab creates your custom restoration.
  • Second visit: The temporary is removed, and the final inlay or onlay is fitted and cemented in place.

  • No temporary filling needed.
  • A permanent, tooth-coloured onlay is made and fitted on the same day.
  • You leave with your tooth restored in a single visit.

Advantages of Inlays and Onlays

  • Stronger and longer-lasting than fillings.
  • Matched to your natural tooth colour.
  • Can last 10+ years with good oral hygiene and regular dental visits.
  • Preserve more tooth structure compared to crowns.

Disclaimer: All dental procedures, including inlays and onlays, carry risks. Outcomes can vary depending on individual circumstances. A consultation with your dentist is necessary to determine the most appropriate treatment for your needs.

Inlays & Onlays – Frequently Asked Questions

With proper care and regular dental check-ups, inlays and onlays can last 10 years or more. Good oral hygiene, such as daily brushing, flossing, and routine professional cleans, will help extend their lifespan.

Most patients are comfortable throughout the procedure. Local anaesthetic is used, so you shouldn’t feel pain during treatment. Some mild sensitivity may occur after the procedure but usually settles quickly.

  • Fillings repair smaller cavities.
  • Inlays repair moderate damage within the cusps of the tooth.
  • Onlays cover one or more cusps, giving extra strength and protection.

No. The porcelain or ceramic used will not respond to teeth whitening. If you’re considering whitening, it’s best to complete that before having an inlay or onlay so the restoration matches your natural teeth.
