CEREC same-day crowns vs traditional crowns — which is right for you?

A patient asked me recently which crown she should have. She'd done her research, she knew the two options, and she wanted a straight answer. I gave her one. This article gives you the same. There's no universally right choice between a same-day CEREC crown and a traditional lab-made crown, but there is almost always a better choice for a given patient and a given tooth. Here's how I think about it.

What is a CEREC crown?

CEREC stands for Chairside Economical Restoration of Esthetic Ceramics. The name's a mouthful. What it means in practice: a machine in the surgery designs and mills a custom porcelain crown while you wait, and the whole thing is done in a single appointment of around two to three hours.

At Bowling Green, we use the CEREC Omnicam system. We are the only dental practice in Stevenage with this technology in-house. The process: I prepare the tooth in the usual way, then take a digital scan of the prepared tooth and surrounding area. No impression material, no tray in your mouth. That scan goes into the CEREC software, where I design your crown on-screen, adjusting the shape, size and contact points. The design then goes to the milling unit in the next room, which carves the crown from a solid block of porcelain in about fifteen minutes. I stain and glaze it to match your natural teeth, fire it briefly, and cement it. You leave with a permanent crown. No temporary, no second appointment, no two-week wait.

What is a traditional lab-made crown?

A traditional crown involves two appointments. At the first, I prepare the tooth and take an impression, either physical or digital, which is sent to a dental laboratory. A dental technician crafts the crown by hand, typically from zirconia or layered porcelain, and posts it back. This usually takes ten to fourteen days. While you wait, I fit a temporary crown to protect the prepared tooth.

At the second appointment, I remove the temporary, check the fit of the lab crown, make any small adjustments, and cement it permanently. A lab-made all-porcelain crown at Bowling Green starts from £700. A CEREC crown starts from £600, so the same-day option is actually cheaper.

The honest comparison

When do I recommend each?

For the vast majority of crown cases, back teeth, premolars, molars, and most straightforward front teeth, I recommend CEREC. The porcelain is extremely strong, the fit is excellent, and sparing the patient a second appointment is a real benefit. For back teeth where strength is the primary requirement, CEREC is my first choice every time.

For front teeth, I assess each case individually. If a patient is having a full smile makeover involving multiple restorations across the whole front arch and the shade matching needs to be perfectly coordinated, a lab crown may offer a marginal advantage in the hands of a very good technician. I'll say so if that applies to your case.

The plain version: don't assume the more expensive or more time-consuming option is better. With crowns, it often isn't.

A note on the material

Older patients may remember metal-ceramic crowns: a metal substructure with porcelain fired on top, often visible as a grey line at the gumline. Neither CEREC nor modern lab crowns use metal. Both use full-ceramic or zirconia materials. They look more natural, they're biocompatible, and there's no dark margin at the gum. It's one of the areas where modern dentistry is unambiguously better than it used to be.

CEREC crowns on front teeth

I fit CEREC crowns on front teeth regularly and the results are consistently good. The CEREC software lets me mirror the shape and texture of adjacent teeth precisely, and the staining and glazing I do before firing adds natural-looking colour. For most front-tooth cases, the result is indistinguishable from a lab crown once it's in place.

The exception: if you're having six or eight veneers and crowns across the whole front arch, a lab working with all the restorations simultaneously might offer a small advantage in shade consistency. But for a single crown or a pair of front teeth, CEREC is entirely appropriate.
