Overview
A dental crown is a custom-made cap that covers and protects a damaged or weakened tooth. The goal is to restore strength, function and appearance while preventing further cracking or breakage.
Best results come from choosing a crown type and timing that fit your diagnosis, how much sound tooth remains, your bite forces, cosmetic goals and budget.
Who typically needs a crown?
- Large fillings with little natural tooth left
- Cracked or fractured teeth (especially biting pain)
- After root canal therapy to prevent breakage
- Broken cusps or heavily worn teeth
- Teeth needing cosmetic rebuilding and strength
Sometimes a less extensive onlay/inlay or a new filling may be suitable. If a tooth is too compromised, extraction and replacement (implant, bridge, or denture) may be discussed.
The dental crown procedure: step-by-step
- Assessment and planning: Exam and x‑rays to confirm a crown is indicated and to check the nerve and roots. Your dentist will discuss materials, aesthetics and cost.
- Numbing and preparation: The tooth is shaped to create space for the crown. If needed, a core build-up is placed to support the crown.
- Scan or impression: Digital intraoral scanning or a traditional impression captures the exact shape for the laboratory or in‑house mill.
- Temporary crown (lab-made route): A temporary crown protects the tooth for 1–2 weeks while the final crown is made.
- Manufacture: Same‑day CEREC style crowns are designed and milled on-site in one visit; lab-made crowns return in about 1–2 weeks.
- Fitting and cementation: The crown is tried in, the bite is adjusted, edges checked and the crown is permanently cemented.
- Review: Any high bite points are adjusted; contact your dentist if you notice persistent tenderness, looseness or a chipped edge.
Timeframe: Same-day crowns take around 1.5–3 hours. Lab-made crowns are usually two visits: 60–90 minutes to prepare/scan and 30–45 minutes to fit.
Same-day vs lab-made crowns
- Same-day (CAD/CAM/CEREC): One visit, no temporary, strong modern ceramics, excellent for many back teeth and some front teeth. Aesthetic layering is limited compared to lab ceramics in highly demanding smile zones.
- Lab-made: Two visits, uses a temporary crown, wide range of materials with layered ceramics for highly natural front-tooth aesthetics, strong choices (e.g., zirconia) for heavy bites.
Both options are widely used in Australia. The right choice depends on the tooth location, cosmetic needs, bite forces and clinic technology.
Crown materials explained
- Zirconia: Very strong, ideal for molars and grinders; slightly less translucent than glass ceramics but improving with newer types.
- Lithium disilicate (e.max): Highly aesthetic and strong; often used for front teeth and premolars.
- Porcelain-fused-to-metal (PFM): Long-standing option with strength from metal and ceramic overlay; can show a grey margin if gums recede.
- Gold alloy: Excellent durability and fit; conservative on opposing teeth; usually chosen for back teeth where appearance is less critical.
Your dentist will match material to your bite, remaining tooth structure and cosmetic priorities.
Cost of dental crowns in Australia
For most clinics, a single dental crown is commonly $1,500–$2,500 per tooth. Prices vary with material, clinic technology (same‑day vs lab-made), preparation complexity and location.
- Extras to consider: X‑rays, core build-up, temporary crown (lab route), and if required, root canal therapy (separate fee).
- Health insurance: Private health extras may contribute to restorative items depending on your policy limits and waiting periods.
- Payment options: Many clinics offer staged treatment or payment plans for larger cases.
If you are comparing a crown to alternatives (large onlay, extraction + implant/bridge), ask for a written plan that separates immediate costs from longer-term options.
Recovery and what to expect
- After preparation: Mild sensitivity to cold or pressure for a few days is common. Temporary crowns may feel slightly different.
- After fitting: Numbness wears off in 2–4 hours. Avoid very hard or sticky foods on the crown for 24 hours while cement fully sets.
- When to call: Persistent bite tenderness, throbbing, or sensitivity that worsens. These can often be resolved with a small adjustment; occasionally the nerve may require further treatment.
Risks, longevity and maintenance
- Longevity: Many crowns last 10–15+ years with good hygiene and bite protection if you grind.
- Potential issues: Bite feels high, edge chipping, cement washout causing looseness, decay at margins if hygiene is poor, rare nerve inflammation.
- Care tips: Twice-daily brushing, daily floss or interdental brushes, a night guard if you clench/grind, and regular check-ups.
Alternatives to a crown
- Onlay/inlay: Conservative option if enough healthy tooth remains.
- Large bonded filling: May work for moderate repairs but less protective for cracked teeth.
- Extraction with replacement: Dental implant, bridge or partial denture if the tooth cannot be saved.
The best choice weighs long-term predictability against upfront cost and the condition of the remaining tooth and gums.
When is it urgent?
- Severe pain, swelling or fever
- Tooth broke below the gumline or sharp edges cutting your tongue/cheek
- Temporary crown lost before your fit appointment
If you have acute symptoms, see an emergency dentist for immediate care, then proceed with definitive treatment.
