A dental crown is like a helmet that goes over the tooth and protects the underlying tooth structure - providing a predictable long term restoration for a weakened tooth. A weakened tooth amongst others is:
- a tooth that has more than 50% of the biting surface covered by a restoration, or
- a tooth that has been root treated or
- a tooth that has been diagnosed with cracks or
- a tooth that has lost a cusp or more due to fracture.
