What Are Dental Crowns and Bridges?
A dental crown is a cap placed over a damaged tooth to restore its shape, strength and appearance. A bridge replaces one or more missing teeth by anchoring artificial teeth (pontics) to the natural teeth or implants on either side of the gap.
Types of Crowns
- Porcelain/ceramic: Best aesthetics, ideal for front teeth. Highly natural appearance.
- Zirconia: Extremely strong and natural-looking. Good for both front and back teeth.
- Metal (gold/alloy): Most durable, ideal for back teeth. Less aesthetic but long-lasting.
- Porcelain-fused-to-metal: Metal core with porcelain exterior. Balance of strength and appearance.
The Process
Getting a crown typically takes two appointments. At the first, the tooth is shaped, an impression is taken, and a temporary crown is fitted. At the second appointment (usually 1 to 2 weeks later), the permanent crown is cemented in place. Some practices offer same-day crowns using CAD/CAM technology.
Costs in the UK
On the NHS, crowns and bridges fall under Band 3 at £306.80. Privately, a single crown costs £400 to £900. A three-unit bridge costs £900 to £2,500. Material choice significantly affects the price.
