CROWNS and ONLAYS

When a cavity becomes too extensive to be predictably restored with a conventional filling, a dental crown or onlay is often the most appropriate solution.
These restorations are also highly effective for teeth that have fractured or have previously undergone root canal treatment.


FAQs
What are crowns and onlays?

Crowns and onlays are precision-crafted restorations, typically fabricated from high-quality porcelain, designed to protect and strengthen compromised teeth. Each restoration is custom-made to restore the tooth’s natural shape, function, and durability while providing enhanced resistance against fracture.
In addition to their protective benefits, crowns and onlays may also be used to refine and enhance the cosmetic appearance of the smile

What does the crown/onlay procedure involve?

Treatment begins with the careful preparation and shaping of the affected tooth to create the ideal foundation for your bespoke restoration. A highly accurate digital scan or impression is then taken and sent to our specialist laboratory.
A beautifully contoured temporary crown or onlay will be placed to protect the tooth while your final restoration is being meticulously crafted — typically over a period of approximately two weeks.
At your review visit, the temporary restoration is gently removed and your custom-made crown or onlay is precisely fitted, adjusted, and securely bonded into place.

How long does the procedure take?

Treatment is typically completed over two appointments.
•    First visit: Approximately 60–90 minutes, during which the tooth is prepared and a temporary restoration is placed.
•    Second visit: Usually 30–45 minutes, where your bespoke crown or onlay is carefully fitted and finalised.

What is the difference between a crown and an onlay?

A crown is designed to fully encase the entire visible portion of the tooth, providing comprehensive coverage and strength. An onlay, by contrast, is more conservative and typically restores the biting surface and selected sides of the tooth.
Onlays are adhesively bonded and allow us to preserve as much healthy natural tooth structure as possible. When clinically appropriate, they represent a refined, tooth-preserving solution — though they do require a high level of technical precision to place successfully.
