What to Expect During Your CEREC Appointment: From Scan to Final Crown in One Visit

If you've been told you need a crown and your dentist has mentioned CEREC, you're probably wondering what exactly this appointment will involve. The good news? You'll walk out with your permanent crown the same day. No temporary crown, no second appointment, no waiting weeks for a lab to fabricate your restoration.

As a dentist who has performed thousands of CEREC procedures, I want to walk you through exactly what happens during this appointment so you know what to expect. While every case is slightly different, the process follows a predictable sequence that typically takes 1-2 hours from start to finish.

Before We Begin: Understanding CEREC Technology

CEREC stands for Chairside Economical Restoration of Esthetic Ceramics. In simple terms, it's a computer-controlled system that allows your dentist to design and create your crown right in the office. Instead of taking messy impressions and sending them to a lab, we use a digital scanner to capture precise 3D images of your tooth, design your crown on a computer, and mill it from a block of ceramic material—all while you wait.

This isn't experimental technology. CEREC has been around for over 30 years, and clinical studies show that CEREC restorations have an 84.4% survival rate after 18 years, with success rates of 94% for crowns on natural teeth.

Step 1: Numbing and Tooth Preparation (15-20 minutes)

Your appointment begins just like any traditional crown procedure. After reviewing your treatment and answering any questions, we'll administer local anesthetic to ensure you're completely comfortable. Most patients report feeling nothing more than a small pinch from the injection.

Once you're numb, I'll prepare your tooth by removing any decay and shaping it to accommodate the crown. This involves removing a small amount of tooth structure—typically about 1-2 millimeters—from all surfaces. You'll hear the sound of the dental handpiece, but you shouldn't feel any discomfort.

The preparation needs to be precise because it creates the foundation for your new crown. Unlike traditional methods where small imperfections might be corrected by the lab technician, CEREC requires accuracy from the start since the computer will mill exactly what we design.

Step 2: Digital Scanning (5-10 minutes)

Here's where CEREC really shines compared to traditional crown procedures. Instead of filling your mouth with impression putty that can be messy and uncomfortable, we use a small digital camera called an intraoral scanner.

The scanner looks like a small wand with a camera tip. I'll move it around your prepared tooth and surrounding area, taking hundreds of digital photographs that the computer assembles into a precise 3D model. The process is completely painless—you'll just need to keep your mouth open while I capture the images.

You might taste a light powder that we sometimes apply to your teeth before scanning. This helps the camera capture even more detailed images by eliminating any reflective surfaces. The powder is completely harmless and rinses away easily.

One of the benefits patients love about this step is that you can watch the 3D model of your teeth appear on the computer screen in real-time. Many patients are fascinated to see their teeth from this perspective.

Step 3: Crown Design (10-15 minutes)

Once we have your digital scan, I'll use CEREC's design software to create your crown. This is where the artistry meets technology. The software provides an initial crown design based on your tooth's anatomy and the surrounding teeth, but I refine this design to ensure proper fit, function, and appearance.

During this phase, you can relax in the chair or even take a short break if needed. Some patients enjoy watching the design process on the computer monitor—it's quite fascinating to see your crown take shape digitally. I'll adjust the crown's shape to ensure it fits perfectly with your bite and matches the contours of your natural teeth.

The software considers factors like:

• The exact shape and size of your prepared tooth
• How your upper and lower teeth come together when you bite
• The natural anatomy and proportions that will look most natural
• Proper contact points with adjacent teeth

This digital design phase is crucial. While it might seem like I'm “just clicking buttons,” I'm making dozens of micro-adjustments to ensure your crown will be comfortable and function properly for years to come.

Step 4: Milling Your Crown (15-20 minutes)

Once the design is finalized, we send it to the CEREC milling unit. This machine uses diamond-coated burs to precisely carve your crown from a solid block of ceramic material. The milling process is automated and incredibly accurate—we're talking about precision measured in microns.

You'll hear the milling unit working in the background. It sounds similar to a dental handpiece but runs continuously for about 15-20 minutes depending on the complexity of your crown. During this time, you can rest, listen to music, or even take a bathroom break.

The ceramic blocks we use come in various shades to match your natural teeth. I select the shade that best matches your existing teeth before we begin milling. These ceramic materials are incredibly strong—often stronger than your natural tooth enamel—and highly biocompatible.

Step 5: Sintering and Finishing (20-30 minutes)

When your crown comes out of the milling unit, it looks like your finished crown but needs additional processing to reach its full strength and optimal appearance. We place it in a sintering furnace, which heats the ceramic to about 1,500°F. This process fuses the ceramic particles together, creating maximum strength and bringing out the natural translucency that makes the crown look like a real tooth.

While your crown is in the furnace, we'll clean and prepare your prepared tooth for the final cementation. This is a good time to take another break, use the restroom, or grab a drink of water.

Once the sintering cycle is complete, I'll remove your crown from the furnace and perform any final adjustments. This might include smoothing rough edges or making minor shape modifications to ensure perfect fit and comfort.

Step 6: Try-In and Final Adjustments (10-15 minutes)

Now comes the exciting part—trying in your new crown. I'll place the crown on your prepared tooth to check the fit, bite, and appearance. In most cases, the fit is excellent right from the milling unit, but I'll make any necessary adjustments.

I'll check several things during the try-in:

• Marginal fit: Ensuring the crown fits precisely at the gum line
• Contact points: Making sure the crown touches adjacent teeth properly
• Bite relationship: Verifying that your bite feels natural and comfortable
• Appearance: Confirming that the color and shape look natural

If any adjustments are needed, I can make them chairside using specialized instruments. This might involve minor reshaping or polishing to perfect the fit and bite.

Step 7: Cementation (5-10 minutes)

Once we're both satisfied with the fit and appearance, it's time for the final step: permanently cementing your crown. I'll clean both your prepared tooth and the inside of the crown, then apply a strong dental cement.

The crown is placed on your tooth and held in position while the cement sets. Depending on the type of cement used, this might involve using a special curing light to harden the material quickly, or simply waiting a few minutes for chemical curing.

After the cement has set, I'll remove any excess material and check your bite one final time. You'll be able to feel immediately that your new crown is secure and comfortable.

What Does It Feel Like?

Many patients are surprised by how comfortable the CEREC process is. The most uncomfortable part is typically the initial injection for numbing, which is the same for any dental procedure. The digital scanning feels like someone moving a small camera around your mouth—no pressure, no gagging from impression materials.

During the milling and sintering phases, you can relax completely. Some patients even take a short nap during these waiting periods. The entire process is much less stressful than traditional crown procedures because you're not dealing with temporary crowns or multiple appointments.

Immediate Aftercare

Once your CEREC crown is cemented, you can use it immediately. However, I recommend waiting until the numbness wears off before eating to avoid accidentally biting your tongue or cheek.

Your new crown might feel slightly different from your natural tooth initially—this is completely normal. Your tongue is incredibly sensitive and will notice even the smallest changes. Most patients adapt to their new crown within a few days.

Some patients experience mild sensitivity to temperature for a few days after the procedure. This typically resolves on its own as your tooth adjusts to the new restoration.

Success Rates and Longevity

CEREC crowns have excellent long-term success rates. Clinical studies show 91-94% success rates, and many CEREC crowns last 15-20 years or longer with proper care. The key to longevity is maintaining good oral hygiene and avoiding habits like grinding your teeth or chewing on hard objects.

Research involving over 2,300 CEREC restorations showed a 95.5% success rate after 9 years, demonstrating the reliability of this technology.

When CEREC Might Not Be the Best Option

While CEREC is excellent for most crown cases, it's not always the ideal solution. I might recommend traditional lab-made crowns in certain situations:

• Complex cases requiring multiple crowns that need precise color matching
• Situations where the prepared tooth is in a difficult location for digital scanning
• Cases requiring specialized ceramic materials not available in CEREC blocks
• Patients with severe gag reflexes who have difficulty with the scanning process

As your dentist, I'll always recommend the best treatment option for your specific situation, whether that's CEREC or traditional methods.

Cost Considerations

CEREC crowns are typically priced similarly to traditional lab-made crowns. While the technology is sophisticated, the elimination of lab fees and the efficiency of single-visit treatment often balances the cost. Many patients find that the convenience of completing treatment in one visit is worth any potential cost difference.

Studies show that 50% of dental patients are willing to pay more for high-tech CAD/CAM restorations like CEREC, primarily due to the convenience and improved experience.

Frequently Asked Questions

How long does a CEREC appointment actually take?

Most CEREC crown appointments take 1.5 to 2 hours from start to finish. Simple cases might be completed in about an hour, while more complex situations could take up to 2.5 hours. The exact time depends on the complexity of your case and whether any additional procedures are needed.

Will my CEREC crown look natural?

Yes, CEREC crowns are made from high-quality ceramic materials that closely mimic the appearance of natural teeth. The digital design process allows for precise color matching and natural-looking contours. Most people won't be able to tell the difference between your CEREC crown and your natural teeth.

Can I eat normally right after my CEREC appointment?

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 you might want to avoid very hard or sticky foods for the first day while you adjust to your new crown.

What happens if my CEREC crown doesn't fit properly?

This is rare, but if there are fit issues, I can make adjustments immediately since we're doing everything in the office. Minor adjustments are common and expected—every patient's mouth is unique, and fine-tuning ensures optimal comfort and function. In the unlikely event of a major issue, we can remake the crown the same day.

How do I care for my CEREC crown?

Care for your CEREC crown just like your natural teeth—brush twice daily, floss regularly, and maintain routine dental checkups. Avoid chewing on hard objects like ice or using your teeth as tools. With proper care, your CEREC crown should last 15-20 years or longer.
