Filling / Inlay / Onlay
Thoughtful options to repair a damaged tooth and preserve as much healthy tooth structure as possible.
Tooth decay, a chipped tooth or an older restoration can sometimes be treated without covering the whole tooth. A filling, inlay or onlay replaces the affected area. The right option depends on how much sound tooth remains, where the damage is and how the tooth meets your bite.
Your options
Three ways to restore a tooth
Each treatment is planned for the tooth in front of us — there is no single choice that suits every case.
Filling
A filling repairs a cavity or a small area of damage. After the affected area is prepared, the material is placed and shaped in the tooth. A tooth-coloured filling can blend with the surrounding enamel.
Inlay
An inlay is made to fit a prepared area within the chewing surface, between the tooth's raised edges (cusps). It may be considered when a direct filling is not the best option for the size or shape of the area.
Onlay
An onlay covers the chewing surface and extends over one or more weakened cusps. It can restore a larger area while retaining healthy parts of the natural tooth, where clinically suitable.
What to expect
Assessment
We examine the tooth, discuss symptoms and may use an X-ray if needed to understand the extent of damage.
Preparation
Any decay or failing restoration is removed. For an inlay or onlay, a scan or impression is taken so the restoration can be made to fit.
Restoration
A filling is placed directly. A custom inlay or onlay is fitted and bonded once ready. The dentist checks the bite and explains aftercare.
The number of visits and the materials used vary with the tooth and the treatment plan. We will explain these before you decide.
Common questions
Will treatment be uncomfortable?
Local anaesthetic can be used when appropriate. Tell your dentist if you feel anxious or uncomfortable so they can talk through the options with you.
How long will the restoration last?
There is no fixed lifespan. Durability depends on the size and position of the restoration, the material, your bite and how you care for your teeth. Your dentist can explain what to expect for your case.
Can every damaged tooth have an inlay or onlay?
No. The tooth needs a clinical assessment first. If damage is extensive, another restoration or treatment may be more suitable.
