What CEREC actually is
CEREC (Chairside Economical Restoration of Esthetic Ceramics) is a technology platform that lets a dentist design, mill, and bond a permanent porcelain crown in one appointment, typically 90 minutes total.
The traditional crown workflow takes 2-3 weeks across 2 visits with a temporary crown in between. CEREC eliminates the temporary crown phase entirely. We use the same FDA-cleared porcelain materials as traditional crowns — just delivered faster.
How CEREC works step-by-step
The 90-minute CEREC visit
- Local anesthesia + preparation (15 min): Dr. Natalia reshapes the tooth to receive the crown. Same prep as traditional method.
- Digital impression with iTero scanner (5 min): An intraoral camera captures 3D images of your prepared tooth and surrounding teeth. No goopy impression material.
- Crown design with CEREC software (15 min): Dr. Natalia designs the crown on a computer based on the digital impression. The software accounts for your bite, neighboring teeth shape, and proper occlusion.
- Milling the crown (15-20 min): An in-office milling machine cuts the porcelain crown from a small block. This is the high-tech magic.
- Crown try-in and adjustment (15 min): Check fit, color match, bite contact. Fine-tune.
- Final bonding (15 min): Permanent cementation. Polish. Final bite check.
You walk out with a permanent crown that same day.
When CEREC vs traditional crown is right
CEREC works for most cases, but not all.
CEREC is ideal for:
- Single tooth crowns (front or back)
- Replacing existing crowns that failed
- Restoring teeth after root canals
- Repairing chipped or cracked teeth
- Anyone who doesn’t want a second visit
Traditional 2-visit crown may be better for:
- Multi-tooth bridges (CEREC handles single-units best)
- Very complex esthetic cases requiring lab artistry
- Implant crowns with custom abutments
- Patients who specifically want lab-stacked porcelain
Cost & insurance
CEREC same-day crown cost: $1,200-1,800 per tooth, same range as traditional crowns. Most insurance plans cover 50-80%.
- Delta Dental, Aetna, MetLife: typically 50% coverage
- Cigna, BCBS: 50% on most plans
- UnitedHealthcare: 50%
- Medicaid (HealthFirst, Affinity, etc.): some plans cover basic crowns; pre-authorization usually required
- 1199SEIU: 80-100% coverage
CEREC vs lab-fabricated long-term durability
Major question: does CEREC last as long as lab-made crowns?
The answer (per published research): yes, equivalent. 15-20 year survival rates are similar between in-office milled CEREC and lab-fabricated crowns using the same porcelain materials.
What matters more than the milling location:
- Quality of the tooth preparation
- Quality of the bonding
- Patient bite forces and habits (grinding)
- Maintenance (cleanings, no biting hard objects)
Frequently asked questions
Does CEREC look as natural as a lab-made crown?
For most cases yes. CEREC porcelain comes in a range of shades that match natural teeth excellently. For very high-esthetic front-tooth cases (especially when matching to multiple natural teeth), lab-stacked porcelain has slight aesthetic advantages but at the cost of a second visit.
How long does the CEREC crown last?
15-20+ years average. Same range as traditional crowns. Depends on materials, oral hygiene, and biting forces.
Can I eat normally right after CEREC?
Yes — once anesthesia wears off (2-3 hours), you can eat normally. The crown is fully cured and bonded.
Does CEREC hurt more than traditional crowns?
No — same preparation, same anesthesia. Just no temporary crown phase. Post-procedure discomfort 24-48 hours is similar.
Why isn’t every dentist doing CEREC?
The CEREC machine costs $100K-150K. Many dentists don’t justify the equipment cost for their volume. We’ve been using CEREC since the practice opened in 2018 — it’s worth it for our patients.
