Start with what matters to you.
I have a large old filling.
Ask what is sound underneath and how much tooth would need preparing.
I want it to look natural.
Ask about material choice, colour matching and how visible the restoration will be.
I have been offered a crown.
Ask why full coverage is recommended and whether a partial restoration is suitable.
Understanding Inlays & Onlays.
An inlay or onlay is a custom-made piece used to rebuild a damaged tooth. An inlay fits inside the damaged area. An onlay also covers part of the chewing surface. It can be an option between a standard filling and a crown that covers the whole tooth.
Filling, Onlay or Crown?.
An Inlay
Fits within a prepared cavity. Materials can include ceramic, composite or metal, depending on the design.
An Onlay
Also covers part of the chewing surface. Ask how it supports the remaining tooth.
A Crown
Provides more extensive coverage. It may need more preparation than a partial restoration.
What Happens During Treatment.
Your dentist confirms the stages and timing for your own treatment plan.
Assess the Remaining Tooth
The dentist checks damage, decay and the bite. Discuss whether a filling or another repair could work and whether the tooth needs other treatment first.
Prepare and Take a Record
The damaged area is prepared and a scan or mould is taken. An inlay fits inside the tooth; an onlay also covers part of the biting surface. A temporary filling may be used while it is made.
Fit and Check
The new piece is checked for fit, appearance and bite, then secured. Some practices make suitable repairs or replacement teeth in one visit; others use a laboratory.
Look After the Tooth
Clean around it and attend check-ups. Contact the practice if it feels high, loose or persistently sore.
The exact appointments and recovery time depend on your assessment and the treatment agreed with your dentist.
Your Options with This Treatment.
Things to Consider.
The tooth needs preparation. A restoration may loosen, chip or need replacement, and further treatment can sometimes be needed. Ask how your bite and any grinding affect the choice of material and design.
Your Inlays & Onlays questions.
Is an Onlay the same as a crown?
No. An onlay covers selected surfaces; a crown provides more extensive coverage.
Will I need more than one visit?
Ask how the practice makes the restoration and whether a temporary is required.
How long will it last?
Longevity varies with the tooth, material, bite and care. Ask about maintenance and what could shorten its life.
