What to Expect During Your CEREC Crown Appointment: A Patient's Complete Guide

If you've been told you need a crown and your dentist has mentioned CEREC, you're probably wondering what makes this different from traditional crowns—and what exactly happens during the appointment. The short answer? You'll walk out with your permanent crown the same day, typically within 2 hours.

As a practicing CEREC dentist, I've guided thousands of patients through this process. While the technology is impressive, I know most patients care more about what they'll experience than the technical details. Let me walk you through exactly what happens during your CEREC crown appointment, so you know what to expect every step of the way.

Before Your Appointment: What You Should Know

Your CEREC crown appointment will likely be longer than a typical dental visit—plan for about 2 hours from start to finish. Some appointments can be completed in as little as 1 hour, while more complex cases might take slightly longer.

Unlike traditional crowns that require two separate visits with a temporary crown in between, CEREC allows us to complete your entire crown in one appointment. This means no messy impressions, no temporary crown that might come loose, and no second visit for placement.

You'll want to eat before your appointment since you'll be numb for several hours afterward. Also, if you're anxious about dental procedures, discuss sedation options with your dentist beforehand—the same sedation methods available for traditional crowns work for CEREC appointments too.

Step 1: Tooth Preparation (15-30 minutes)

Your appointment begins just like a traditional crown procedure. After numbing the area with local anesthetic, your dentist will prepare your tooth for the crown.

This involves:

• Removing any decay – If your crown is needed due to a large cavity, all decayed material must be removed first
• Shaping the tooth – Your tooth is carefully reshaped to create room for the crown while maintaining enough structure for a strong foundation
• Refining the margins – The edges where your crown will meet your natural tooth are precisely shaped

This part feels identical to traditional crown preparation. You'll hear the dental drill, feel some vibration, but no pain thanks to the anesthetic. Your dentist will frequently check that you're comfortable and may apply additional numbing if needed.

Step 2: Digital Impressions (10-15 minutes)

Here's where CEREC differs dramatically from traditional crowns. Instead of biting into putty-like impression material (which many patients find uncomfortable), your dentist uses a small digital scanner about the size of a thick pen.

The scanning process involves:

• Drying your tooth – A small amount of air removes saliva from the prepared area
• Optional powder application – Some CEREC systems require a light dusting of scanning powder, though newer systems often don't need this
• Digital scanning – Your dentist moves the scanner around your tooth, capturing thousands of data points to create a precise 3D model

The scanner doesn't touch your tooth directly, so you'll only feel the gentle air flow. Most patients find this much more comfortable than traditional impressions. The scanning takes several minutes as your dentist captures images from multiple angles.

You can actually watch your tooth appear on the computer screen in real-time, which many patients find fascinating. The software creates a detailed 3D model that's far more accurate than traditional impressions.

Step 3: Crown Design (10-20 minutes)

Once scanning is complete, your dentist uses CEREC software to design your crown. This is where the technology really shines—what once required a dental lab technician can now be done chairside.

During the design phase:

• Initial crown shape – The software proposes a crown design based on your tooth's original anatomy and surrounding teeth
• Customization – Your dentist adjusts the crown's shape, size, and contours to ensure proper fit and bite
• Margin refinement – The edges where your crown meets your natural tooth are precisely defined
• Bite adjustment – The chewing surface is designed to match your natural bite pattern

Many dentists will show you the proposed design on screen and explain what they're adjusting. This is a great time to ask questions about the crown's shape or appearance.

The design software is sophisticated, but it's not magic. Your dentist's experience and clinical judgment are crucial during this phase to ensure your crown will be comfortable and functional.

Step 4: Crown Milling (15-20 minutes)

Once your dentist approves the design, it's sent to the CEREC milling machine. This compact unit, usually located in the same room or nearby, carves your crown from a solid block of dental ceramic.

During milling:

• Material selection – Your dentist chooses a ceramic block that matches your tooth color
• Automated milling – Diamond-coated tools precisely carve your crown according to the digital design
• Quality check – Your dentist inspects the milled crown for accuracy and completeness

The milling process is surprisingly quiet—more like a gentle humming than loud grinding. Many patients are amazed to see their custom crown emerge from what started as a plain ceramic block.

This is typically when you can take a break, use the restroom, or simply relax. Some practices have entertainment options or refreshments available during this phase.

Step 5: Crown Finishing and Polishing (10-15 minutes)

Your crown comes out of the milling machine looking good, but it's not quite ready for placement. Your dentist will refine and polish it to perfection.

Finishing steps include:

• Surface smoothing – Any minor roughness from the milling process is polished away
• Margin refinement – The edges are carefully finished to ensure a precise fit
• Glaze application – Some crowns receive a glaze that's fired in a small oven to create a natural-looking surface
• Final polishing – The crown is polished to match the sheen of your natural teeth

If your crown needs glazing, this adds about 10-15 minutes to the process while the crown is fired in a ceramic oven. Not all CEREC crowns require this step—it depends on the material used and your specific needs.

Step 6: Crown Placement and Bonding (15-20 minutes)

The final step is placing your completed crown. Your dentist will first try it in to check the fit, bite, and appearance before permanently bonding it.

The placement process involves:

• Fit verification – Your dentist checks that the crown seats properly and the margins are precise
• Bite adjustment – You'll bite down on special paper to identify any high spots that need adjustment
• Color and appearance check – Final verification that the crown matches your natural teeth
• Bonding preparation – Both your tooth and crown are prepared with special bonding agents
• Final cementation – The crown is permanently bonded to your tooth using dental cement
• Final polish – Any excess cement is removed and the crown is given a final polish

Your dentist may make minor adjustments to the crown's shape or bite during this phase. Small refinements are normal and help ensure your crown feels natural.

What Does It Feel Like?

Most patients are surprised by how comfortable the CEREC process is. The tooth preparation feels the same as any dental procedure under local anesthetic—you'll feel pressure and vibration but no pain.

The digital scanning is actually pleasant for most people. There's no gagging from impression material, no bad taste, and no anxiety about breathing while your mouth is full of putty.

The longest part of the appointment is simply waiting while your crown is designed and milled. Many patients use this time to rest, listen to music, or catch up on their phone.

By the end of your appointment, your mouth may feel tired from being open for an extended period, but this is normal and temporary.

Immediately After Your Appointment

When you leave the office, you'll have your permanent crown in place. However, you'll still be numb from the local anesthetic for several hours.

Important post-appointment considerations:

• Avoid eating until the numbness wears off to prevent accidentally biting your tongue or cheek
• Your bite may feel different initially—this is normal as you adjust to your new crown
• Some sensitivity to temperature or pressure is normal for the first few days
• Avoid hard or sticky foods for the first 24 hours while the cement fully sets

Most patients are amazed that they're leaving with their permanent crown the same day. There's no fragile temporary crown to worry about and no need to schedule a follow-up appointment for crown placement.

Is CEREC Right for Everyone?

While CEREC technology is impressive, it's not the best choice for every situation. CEREC works excellently for single crowns on most teeth, but traditional lab-made crowns might be better for:

• Complex cases requiring multiple connected crowns
• Situations where very specific color matching is critical
• Cases where the strongest possible materials are needed
• Patients who prefer shorter appointments spread over multiple visits

Your dentist will recommend CEREC only when it's the best option for your specific situation.

Frequently Asked Questions

Will my CEREC crown look natural?

Yes, CEREC crowns are made from high-quality dental ceramics that closely mimic natural tooth enamel. Your dentist selects the ceramic block color to match your surrounding teeth, and the final crown is polished to have a natural appearance. Most people can't tell the difference between a well-made CEREC crown and your natural teeth.

How long do CEREC crowns last?

CEREC crowns have excellent longevity, with clinical studies showing survival rates around 95% at 5 years. With proper care, many CEREC crowns last 10-15 years or longer. Their durability is comparable to traditional lab-made crowns, and the precise digital fit often contributes to their longevity.

Is the CEREC appointment more expensive than traditional crowns?

CEREC crown fees are typically comparable to traditional crowns. While you might pay slightly more for the convenience and technology, you save time and money by avoiding a second appointment. There's no temporary crown fee, and you don't need to take additional time off work for a second visit.

What if my CEREC crown doesn't fit properly?

The digital precision of CEREC typically results in excellent fit, but if adjustments are needed, your dentist can make them immediately since you're still in the chair. Minor bite adjustments are normal and can be completed in a few minutes. If major issues arise (which is rare), your dentist can design and mill a new crown the same day.

Can I eat normally right after getting my CEREC crown?

You should wait until the numbness from the local anesthetic wears off before eating to avoid accidentally biting your tongue or cheek. Once the numbness is gone, you can eat normally, though it's wise to avoid very hard or sticky foods for the first 24 hours while the cement fully cures. After that, your CEREC crown can handle normal chewing forces just like a natural tooth.
