TL;DR
- CEREC crowns are ceramic crowns designed, milled, and placed in a single appointment using in-office CAD/CAM technology.
- The main advantages are same-day convenience, no messy impressions, and a precise digital fit.
- The main disadvantages are a higher upfront cost compared to traditional lab-fabricated crowns and limited suitability for certain clinical situations.
- For most standard crown cases on molars and premolars, CEREC is a clinically sound option with a well-documented long-term track record.
What Is a CEREC Crown and How Does It Differ from a Traditional Crown?
A CEREC (Chairside Economical Restoration of Esthetic Ceramics) crown is an all-ceramic dental crown designed, milled, and seated in a single dental appointment using in-office computer-aided design and manufacturing (CAD/CAM) technology. In contrast, traditional dental crowns are typically completed over two visits spaced a few weeks apart, with a temporary crown placed in between.
While the convenience of CEREC crowns is appealing, not every case is suited to this approach. At Norwood Dental, we advise patients to consider the advantages, limitations, and long-term suitability of both options before making a decision.
The sections below outline what you need to know to choose the most appropriate treatment for your needs.
Advantages of CEREC Crowns
The advantages of CEREC crowns start with a clear upside: the entire process is compressed into one visit. Here is what that means in practice:
1. Same-Day Completion
Traditional crowns require a first appointment to prepare the tooth and take an impression, a 2-3 week wait while the crown is fabricated at an off-site lab, and a second appointment to seat it. CEREC eliminates both the wait and the return visit. For patients with busy schedules or those who need a crown before a specific event, same-day placement is a significant practical advantage.
2. No Temporary Crown
Between appointments with a traditional crown, a temporary crown protects the prepared tooth. Temporaries can come loose, crack, or cause sensitivity, and they require patients to avoid certain foods for weeks. Because a CEREC crown is placed the same day, there is no temporary crown period and none of its associated complications.
3. No Goopy Impressions
Traditional crown fabrication requires a physical impression taken with a tray of putty, a process many patients find uncomfortable or gag-inducing. CEREC replaces this with a digital intraoral scan: a small wand captures a precise 3D model of the tooth in seconds. The scan is more comfortable, takes less time, and often produces a more dimensionally accurate record than a physical impression.
4. Precise Digital Fit
Because the crown is designed and milled directly from the digital scan in the same appointment, the fit is based on an exact digital model of the prepared tooth. Norwood Dental’s CEREC® system produces crowns to precise specifications, which reduces the number of adjustments needed before the crown is cemented.
Disadvantages of CEREC Crowns
A balanced look at the disadvantages of CEREC crowns matters before deciding:
1. Higher Upfront Cost
CEREC equipment represents a significant investment for a dental practice, and that cost is reflected in the fee for the crown. In many cases, a CEREC crown costs more than a traditional lab-fabricated crown. However, at Norwood Dental, our exclusive dental savings plan helps reduce the cost of overall treatment without the limitations commonly associated with traditional insurance.
2. Aesthetic Limitations in Some Cases
CEREC crowns are milled from a single ceramic block, which means the layering and characterization techniques a skilled lab technician applies to hand-crafted porcelain crowns are not possible. For most posterior (back) teeth, this is not a concern, and the fit and durability are excellent. For highly visible front teeth where nuanced color matching matters, some dentists prefer a lab-fabricated crown because a technician can build in translucency and shade variation that a milled block cannot replicate.
3. Not Suitable for Every Clinical Situation
CEREC works well for single crowns on teeth with adequate remaining structure. Cases involving severely broken-down teeth, complex bite issues, or full-mouth rehabilitation may still require traditional lab fabrication for optimal results. Your dentist will assess whether CEREC is appropriate for your specific tooth before recommending it.
Are CEREC Crowns as Durable as Traditional Crowns?
For most routine cases, CEREC crowns are considered just as durable as traditional all-ceramic crowns. They are made from high-quality ceramic materials such as lithium disilicate or feldspathic porcelain, which are designed to handle normal biting and chewing forces effectively.
With proper placement and good oral care, CEREC crowns typically last around 10 to 15 years, and in many cases, even longer. This lifespan is similar to that of crowns made in a dental laboratory.
The key variable is the dentist’s preparation technique and the accuracy of the digital scan, both of which directly affect how well the crown seats and how long it lasts. Dr. Dan Ross, Dr. Brandon Bussler, and Dr. Kristina LeCount at Norwood Dental are trained in CEREC® crown placement and use the system regularly in their practice.
Should You Choose a CEREC Crown?
For the majority of patients needing a crown on a back tooth, CEREC crowns offer a straightforward, same-day solution with no meaningful clinical compromise. The decision becomes more nuanced for front teeth, complex restorations, or patients where cost is the primary concern.
The most useful question to ask at your appointment is not “CEREC or traditional?” but “which option gives the best result for this specific tooth?” because the answer genuinely depends on the tooth’s location, the amount of remaining structure, your bite, and your aesthetic priorities. Norwood Dental’s team will walk you through that assessment so you leave with a clear picture of your options.

Frequently Asked Questions
Most CEREC crown appointments take 1.5-2.5 hours from preparation through final placement. The milling process itself takes approximately 15-20 minutes while you wait in the chair.
For back teeth, yes. The fit and color are indistinguishable in normal use. For highly visible front teeth, some dentists prefer a lab-fabricated crown for more refined shade layering, though CEREC results are acceptable in most cases.
Clinical studies show CEREC crowns lasting 10 to 15 years or longer with proper care. Longevity depends on the tooth location, bite forces, oral hygiene, and whether a night guard is used if you grind your teeth.
Yes, but it is a case-by-case decision. Some dentists prefer lab-fabricated crowns for front teeth, where subtle shade layering matters most. Dr. Ross, Dr. Bussler, or Dr. LeCount will advise based on your specific tooth.
The procedure is generally comfortable and is carried out under local anesthesia, similar to a traditional crown. Some mild sensitivity may occur after the appointment, but this usually settles within a few days.
