These options are considered when a tooth is significantly damaged, weakened, or missing. A crown covers and supports a single tooth, while a bridge replaces one or more missing teeth by attaching to the surrounding teeth for support.
What Are Crowns and Bridges?
A crown (sometimes called a cap) covers the visible part of a tooth above the gum line. It is often recommended when a tooth is cracked, heavily decayed, or has had root canal treatment. A crown helps protect the remaining tooth structure and allows the tooth to function normally.
A bridge is used to replace one or more missing teeth. It usually consists of crowns on the teeth next to the gap (called abutments) and an artificial tooth (called a pontic) that fills the space. A bridge helps support normal chewing and prevents nearby teeth from moving out of position.
Both crowns and bridges are fixed restorations, meaning they are securely bonded in place and cannot be removed by the patient. They are designed to support chewing, maintain tooth alignment, and help preserve bite stability.
When Crowns or Bridges May Be Recommended
Crowns or bridges may be advised in situations such as:
- A tooth is too damaged for a standard filling due to decay, fracture, or weakness.
- A tooth has had root canal treatment and needs protection from breaking.
- A tooth is cracked or worn and not suitable for simpler restorative options.
- One or more teeth are missing, and nearby teeth can act as supports for a bridge.
- An existing filling has failed several times.
- Adjustments to the shape or strength of teeth are needed after other treatments.
The decision is based on several factors, including how much healthy tooth remains, the amount of biting pressure in the area, gum and bone health, and the condition of nearby teeth.
