What is a crown?
- To fit a crown, the tooth is reduced and covered by a custom-made restoration
- It can be all-ceramic and thus metal-free
- It must be done immediately if the pulp and nerves have been exposed
How is an all-ceramic crown different from conventional crowns?
- It is a metal-free crown
- No dark metal rim is seen in the gum
- It appears like your normal teeth, without having the opaque (milky) colour of the conventional crowns
When is it a good choice?
- Extensive tooth decay
- Large tooth fracture
- Severe tooth stains
- Closing of a small “gap” between front teeth
- Smile make-over
- Beautiful aesthetic results
- Best for extensive discolouration
- Loss of natural structure of the tooth, therefor not recommended for stained, but otherwise healthy teeth.
- Sometimes requires considerable reduction of the teeth resulting in pulp death which would require root canal therapy
- Higher cost
- More office visits needed
- May decay when there is loss of cement
- Fracturing is possible
- Oversized crowns may be more harmful
