CEREC same-day crown: as good as a lab crown?
· 6 min read
For the vast majority of teeth, yes: a well-made CEREC crown is comparable in strength and longevity to a lab-made crown. The difference is the process — milled from ceramic in the clinic and placed the same day, in a single visit — not the quality. A lab keeps the edge mainly for some front-tooth aesthetic cases.
What is a CEREC crown?
'CEREC' refers to a CAD/CAM system — computer-aided design and manufacturing — applied to dentistry. In practice: rather than sending a paste impression to an outside lab, the dentist scans the tooth with an optical camera, designs the crown on screen, then mills it on site from a ceramic block. The crown is therefore ready and placed the same day, in one appointment.
How it works, in a single visit
Everything happens in the clinic — no second appointment, no lab wait:
- Optical scan — a camera digitizes the prepared tooth; no paste impression, so no gag reflex.
- Design — the crown is drawn on screen and matched to your bite (occlusion).
- Milling — a ceramic block is milled on site in a few minutes.
- Placement — try-in, shade, bonding, and adjustments the same day; you leave with the finished tooth.
Is it as strong as a lab crown?
For the vast majority of cases, yes. The modern ceramic blocks (lithium disilicate, zirconia) milled by CEREC offer strength and longevity comparable to a lab-fabricated crown. The real difference is the workflow — one visit instead of two — not the quality. In practice, fit and lifespan depend far more on the care taken in the preparation and bonding than on whether the crown was milled in-office or at a lab.
When a lab is still the better choice
CEREC isn't the answer to everything, and it's fair to say so. In some cases, a lab ceramist's work remains the better option:
- Highly visible front teeth needing custom characterization and shading that a single-shade block reproduces less finely.
- Complex aesthetic cases — several veneers or crowns that must be harmonized together.
- Severe grinding (bruxism) — material choice matters most (often zirconia), and a night guard protects the crown.
Are you a candidate, and what does it cost?
Most crowns on molars and premolars are excellent CEREC candidates. An assessment — clinical and often radiographic — confirms the tooth has enough healthy structure to be crowned and that CEREC is appropriate in your case. On cost, CEREC crown fees follow the ACDQ fee guide and are comparable to a traditional crown; a written estimate is provided before any treatment, and coverage depends on your insurance plan.
Frequently asked
- Does a CEREC crown last as long as a traditional crown?
- For most teeth, yes — lifespan is comparable. Longevity depends mostly on the bonding, the preparation, and the material chosen, not on whether it was milled in-office.
- Is there a temporary crown to wear?
- No, and that's the main advantage: the final crown is placed the same day. No temporary to wear for one to two weeks, no temporary that comes loose.
- How long is the appointment?
- Usually a single visit, often around 1.5 to 2 hours depending on the case, including scan, milling, and placement.
- Is CEREC ceramic suitable for molars and people who grind?
- Yes, with the right material (zirconia is often preferred for molars and bruxism), and a night guard protects any crown against nighttime wear.
- Is it covered by insurance?
- A CEREC crown is generally treated like a standard crown by plans; coverage varies by your plan. A written estimate is provided before treatment.
