CEREC Same-Day Crowns: How They Work and What to Expect

Step 1: Digital Impression

After numbing the tooth and shaping it to receive a crown, the dentist uses a small wand-shaped intraoral scanner. The scanner takes a series of optical images and stitches them into a 3D model on a computer screen. There is no putty tray and no impression material to swallow or gag on ^[2].

Patient resources note that digital impressions are generally well tolerated, particularly for people who have struggled with traditional impressions in the past ^[2].

Step 2: Computer-Aided Design

The dentist uses design software to plan the shape, size, and bite of the new crown. The software references the scan of the prepared tooth, neighboring teeth, and the opposing arch. The dentist adjusts contours and contact points before sending the design to the mill.

This step typically takes a few minutes. The clinician can fine-tune the occlusion, which is how the upper and lower teeth meet, before any milling begins.

Step 3: Milling the Crown

The design file is sent to a small milling unit in the office. A solid block of dental ceramic, chosen to match the shade of your other teeth, is loaded into the mill. Diamond burs carve the crown from the block, usually in about 10 to 20 minutes ^[1].

After milling, the crown may be polished, stained, or fired in a small oven called a furnace, depending on the ceramic material used. The clinician then tries it in your mouth to check fit, contacts, and bite.

Step 4: Bonding and Finishing

Once the fit and shade look right, the dentist bonds the crown to the prepared tooth with dental cement or an adhesive resin. The bite is checked again and any final polishing is done. You leave the same appointment with a finished crown rather than a temporary one ^[1].

Single-Tooth Crowns

The most common use is a single crown on a tooth with a large filling, fracture, or recent root canal. A crown covers and protects the remaining tooth structure. Same-day ceramic crowns can be a good option for both front and back teeth, depending on the material chosen ^[1].

Inlays and Onlays

When a tooth has too much damage for a filling but not enough for a full crown, an inlay or onlay may be used. These partial-coverage restorations are also milled chairside from ceramic blocks. They preserve more natural tooth structure than a full crown ^[1].

Veneers and Cosmetic Cases

Some practices use CEREC to design and mill ceramic veneers, which are thin facings bonded to the front of teeth. Cosmetic cases often involve more design time and may benefit from input from a prosthodontist. You can learn more on the prosthodontics page about how these specialists handle complex esthetic work ^[1].

Implant Crowns

Chairside systems can also be used to fabricate crowns that sit on dental implants. The workflow is similar, but the scan captures a scan body attached to the implant rather than a prepared tooth. Implant cases often involve additional planning steps and may not always be completed in a single visit ^[1].

Regulatory Status

Chairside milling units and intraoral scanners are medical devices. In the United States, devices in this category typically reach the market through FDA 510(k) clearance, which means the manufacturer has shown the device is substantially equivalent to others already on the market. FDA clearance is not the same as FDA approval, which is a more rigorous pathway used for higher-risk devices.

Ask your dentist or prosthodontist about the specific system in their office if you want details about the device, the ceramic materials used, and the manufacturer.

Professional Society Positions

The American College of Prosthodontists publishes patient education about modern crown materials and digital workflows, and presents same-visit ceramic restorations as one of several options that a prosthodontist may offer ^[1].

The American Dental Association also discusses crowns in its patient resources, including the use of digital impressions and tooth-colored ceramic materials ^[2].

What Research Generally Suggests

Clinical reports in restorative dentistry generally describe chairside ceramic crowns as performing similarly to lab-made ceramic crowns when cases are well selected and bonding protocols are followed. Specific survival rates depend on the ceramic material, the tooth involved, and patient factors such as grinding habits. Ask your prosthodontist about the published evidence for the specific material they recommend ^[1].

Potential Benefits

The most visible benefit is time. The entire process is completed in one appointment, which means no temporary crown, no second numbing visit, and no two-week wait. Many patients appreciate skipping the putty impression in favor of a digital scan ^[2].

Because there is no temporary crown, you avoid the risk of a temporary coming loose between visits. The final crown is bonded the same day. The ceramic materials used are tooth-colored, so the result is designed to look like a natural tooth ^[1].

Potential Limitations

Same-day crowns are not always the best fit for every case. Complex esthetic cases on front teeth sometimes benefit from a dental laboratory technician who can layer porcelain by hand. Heavy grinders or patients with very limited remaining tooth structure may need different materials or designs.

The appointment itself is longer than a single visit for a traditional crown, because the design and milling happen while you are in the chair. Plan for roughly one and a half to two hours, depending on the case. Some practices may not offer chairside milling at all, and not every dentist who has the technology uses it for every patient.

Comparison With Traditional Lab Crowns

Traditional lab-made crowns are still a common and well-supported option. They involve a putty or digital impression sent to a lab, a temporary crown for about two weeks, and a second visit to cement the final crown. Either approach can produce a long-lasting, natural-looking result when planned and placed carefully. The choice often comes down to case complexity, material selection, and patient preference ^[1][2].

Typical Cost Ranges

In many United States markets, a single ceramic crown is quoted in the range of roughly several hundred to a few thousand dollars before insurance. Higher-cost markets and complex cases tend toward the upper end. Lower-cost markets and straightforward cases tend toward the lower end. Always ask for a written treatment plan and fee estimate before agreeing to care. Costs vary by location, provider, and case complexity.

Insurance and Payment

Many dental insurance plans cover crowns at least in part, often classifying them as a major service with a waiting period and a percentage co-insurance. Coverage typically does not depend on whether the crown is made chairside or in a lab; it depends on the material and the reason for the crown. Verify benefits with your insurance carrier and ask the practice to submit a pre-treatment estimate when possible.

Patient-facing resources from dental organizations explain how to read a dental insurance plan and what questions to ask about coverage for restorative treatments ^[2].

Finding Providers With CEREC

Not every dental office has a chairside milling system. General dentists and prosthodontists in larger metros are more likely to offer same-day crowns. You can call ahead and ask whether the office provides single-visit ceramic crowns and what materials they use ^[1].
