If you've ever chipped a tooth or needed a crown replaced, you know the drill — multiple appointments, temporary crowns that feel awkward, and weeks of waiting. Same day crowns are changing that experience entirely. In this guide, we'll walk you through how the process works, what the advantages and disadvantages are, and how they stack up against conventional crowns.
What Are Same Day Crowns?
Same day crowns (also called CEREC crowns) are custom dental crowns designed, milled, and placed in a single clinic visit — usually within two to four hours. Instead of sending impressions to an external lab and waiting one to two weeks, your dentist uses in-office CAD/CAM (computer-aided design and manufacturing) technology to create a ceramic crown on the spot.The result: you walk in with a damaged tooth and walk out with a permanent restoration — same day.How the Process Works
The workflow follows a few clear steps:1. Digital ScanningInstead of traditional putty impressions, the dentist uses a small intraoral camera to take a 3D digital scan of your tooth. This is faster, more comfortable, and remarkably precise.2. Crown DesignThe 3D scan is fed into CAD/CAM software. Your dentist — or a trained technician — designs the crown digitally, adjusting the shape, size, and bite fit in real time.3. MillingThe design is sent to an in-office milling machine, which carves the crown from a solid block of ceramic in approximately 15–20 minutes.4. Finishing & BondingThe crown is polished, color-matched, and bonded to your prepared tooth. Your dentist checks the bite and makes any final adjustments before you leave.Total chair time: roughly 2–3 hours, start to finish.Pros of Same Day Crowns
Convenience is the obvious winner. No second appointment, no temporary crown, no waiting. For busy patients or those who experience dental anxiety, consolidating treatment into one visit is genuinely valuable.No temporary crowns. Traditional workflows require a temporary crown while the lab makes the permanent one. Temporaries can come loose, feel uncomfortable, or increase sensitivity. With same day crowns, that step is eliminated entirely.Digital precision. CAD/CAM scanning removes human error from the impression-taking stage. Digital scans are highly accurate and reduce the chance of a poorly fitting crown.Durable ceramic material. Modern same day crowns are made from high-strength ceramic that closely mimics the natural look and feel of teeth.Less exposure for the prepared tooth. Because there's no gap between preparation and final placement, the exposed tooth structure spends less time without protection.Cons of Same Day Crowns
No dental procedure is perfect, and same day crowns have real limitations worth knowing.Not always suitable for every case. Severely damaged teeth, back molars under heavy bite pressure, or cases requiring significant gum work may not be ideal candidates. Your dentist will assess whether it's appropriate for your specific situation.Color matching complexity. While ceramic blocks have improved significantly, achieving a perfect shade match in a single visit can be more challenging than a lab-crafted crown — especially for highly visible front teeth.Technology-dependent. The quality of a same day crown depends on the equipment at the clinic and the dentist's experience with CAD/CAM systems. Not all clinics offer this service at the same standard.Higher upfront cost at some clinics. The in-office milling equipment is expensive, and that can be reflected in the price. That said, when you factor in fewer appointments and no temporary crown, the overall value often balances out.Same Day Crowns vs. Traditional Crowns
For a straightforward comparison:- Appointments needed: 1 (same day) vs. 2–3 (traditional)
- Turnaround time: 2–4 hours vs. 1–2 weeks
- Temporary crown required: No vs. Yes
- Material options: Ceramic (CAD/CAM) vs. ceramic, porcelain-fused-to-metal, or zirconia
- Best for: Most single crown cases vs. complex or multi-unit restorations
