What is a dental crown?
A crown is a tooth-shaped cap that fits over an existing tooth, restoring its shape, strength, and appearance. Think of it as a protective helmet for a damaged or weakened tooth.
Crowns are indicated when:
- A tooth has a crack that extends toward the root
- A cavity is too large for a filling to adequately support the remaining tooth structure
- A tooth has been root canal treated (which leaves it brittle)
- An existing large filling has broken down
- A tooth is severely worn from grinding
- You need an anchor for a dental bridge
Crown options at Innova Smiles
CEREC® Same-Day Ceramic Crowns (most popular)
Our CEREC system mills your crown from a single block of high-strength ceramic right here in the office while you wait. The result is a custom-shaded restoration that matches your natural tooth color and requires only one appointment.
Timeline: 2–3 hours total (prep, scan, mill, cement) Material: Lithium disilicate or zirconia ceramic Best for: Most back teeth and many front teeth, patients who can't take multiple days off
Traditional Lab-Fabricated Crown
We scan or take an impression, send it to a dental lab, and you wear a temporary crown for 2–3 weeks while the lab crafts your permanent restoration.
Timeline: Two appointments, 2–3 weeks apart Material: Porcelain-fused-to-metal (PFM), all-ceramic, or full zirconia Best for: Complex esthetic cases where lab artistry is needed, very posterior molars under heavy bite force
Step-by-step: what happens during crown treatment
Step 1 — Examination and X-rays (30 minutes)
We verify the tooth is a good candidate for a crown. This includes checking the nerve health (to see if a root canal is needed first), assessing surrounding bone on X-rays, and measuring the amount of remaining healthy tooth structure.
Step 2 — Anesthesia and tooth preparation (45–60 minutes)
We numb the tooth and surrounding area thoroughly. The tooth is shaped to create space for the crown — typically removing 1–2mm around the entire circumference and from the top. For most patients using our DentalVibe vibration device, the injection itself is barely noticed.
Step 3 — Digital scan (10 minutes)
Our TRIOS® 5 intraoral scanner takes thousands of micro-images per second, building a precise 3D map of your prepared tooth and the opposing arch. No putty impressions.
Step 4 — Crown design and milling (CEREC: 45–60 minutes)
For same-day crowns, we design your restoration on-screen and the CEREC mill carves it from a ceramic block. For lab crowns, we place a temporary crown and send the digital file to the lab.
Step 5 — Try-in, cementation, and bite check (20–30 minutes)
The crown is placed, bite is checked and refined, and the crown is cemented permanently. You'll leave with a fully functioning tooth.
How long does a crown last?
With proper care, ceramic crowns last 10–25+ years. The key factors are:
- Bite forces — heavy grinders benefit from a night guard to protect crowns from excessive wear
- Oral hygiene — decay at the crown margin (where crown meets tooth) is the most common failure reason
- Flossing technique — slide floss out to the side rather than "snapping" it, which can loosen cement over years
- Regular exams — we check margins and integrity at every hygiene visit
Crown vs. filling: which do I need?
| Factor | Filling | Crown |
|---|---|---|
| Cavity size | Less than ~50% of tooth | More than ~50% of tooth |
| Cracked tooth | Hairline, surface only | Extending toward root |
| Post root canal | Rarely sufficient | Almost always required |
| Existing large filling | If still solid | If broken or showing decay |
| Cost (approximate) | Lower | Higher, but protects the tooth |
When in doubt, it's better to crown a tooth than to watch a large filling fail and risk losing the tooth entirely.

After your crown: what to expect
- Mild sensitivity for 1–4 weeks is normal, especially to temperature
- Bite feels high — call us right away and we'll adjust it (takes 5 minutes, no charge)
- Temporary crown (if you have one): avoid sticky foods like caramel that can pull it off; call us if it comes loose
- Permanent crown: brush and floss normally; use a water flosser if flossing around it feels awkward
If you think you may need a crown, or if you've been told by another dentist that you do, schedule an evaluation at Innova Smiles. We'll confirm whether a crown is the right choice and show you exactly what it would look like using our digital smile design tools.
