What Are Dental Crowns and Bridges?
A dental crown is a cap that covers the whole visible part of a tooth. It restores the tooth’s shape and strength when a filling alone isn’t enough, for example after a large break, heavy wear or a root canal.
A dental bridge replaces one or more missing teeth. The teeth on either side of the gap, called abutment teeth, are crowned, and those crowns hold a false tooth (a pontic) in between. The result is fixed in place, so you don’t take it out like a denture.
Both are made to match the shape and colour of your natural teeth, and both usually need at least two visits because they’re custom-made by a dental laboratory.
When Do You Need a Crown?
- A tooth is cracked, broken or worn down
- A filling is so large that the remaining tooth is weak
- A back tooth has had root canal treatment
- A tooth is badly discoloured or misshapen and other options won’t work
- An old crown has failed or no longer fits well
When Is a Bridge an Option?
A bridge suits a gap where the teeth on both sides are healthy enough to support it. It closes the space, helps you chew and stops neighbouring teeth drifting. If the teeth beside the gap are already heavily filled, crowning them can protect them at the same time.
Materials Comparison
| Material | Strength | Appearance | Often used for |
|---|---|---|---|
| Zirconia | Very high | Good, slightly opaque | Back teeth, bridges, people who grind |
| Lithium disilicate (E.max) | High | Very natural and translucent | Front teeth and premolars |
| Porcelain-fused-to-metal (PFM) | High | Good, may show a grey edge over time | Back teeth, longer bridges |
The materials and laboratory used will be confirmed by the clinic. Ask which material is suggested for your tooth and why.
Planning crowns around a trip
Tell the clinic your arrival and departure dates. Crowns need lab time between visits, so the first appointment works best early in your stay, with a spare day before you fly.
The Visit Sequence
Visit 1: the tooth is numbed and shaped, an impression or digital scan is taken with an intraoral scanner, the shade is matched and a temporary crown is fitted.
Between visits: the dental laboratory makes the final crown or bridge, sometimes using CAD/CAM milling.
Visit 2: the temporary is removed and the final crown is checked for fit, colour and bite before it’s cemented. Small occlusal adjustments make sure it feels natural.
Looking After Crowns and Bridges at Home
- Brush twice daily and clean around the gumline carefully
- Use floss threaders or interdental brushes to clean under a bridge
- Avoid biting ice, bottle caps or very hard food
- Wear a night guard if you grind your teeth
- Keep your treatment summary with your dental records
