Can a crown restore a tooth with half its visible part missing?
A crown may restore a tooth with half its visible structure missing if the remaining tooth and root can support a stable foundation.
What determines whether the remaining tooth can support a crown?
The dentist assesses remaining enamel and dentine, the pulp, root, ferrule, bite, gum level, and supporting bone. Decay or fracture may make a crown unsuitable.
What treatments may prepare a badly damaged tooth for a crown?
Treatment can involve removing decay, a bonded build-up, pulp treatment, a post-supported core in selected cases, and crown preparation.
When does a broken tooth need prompt dental assessment?
Arrange prompt care for a broken tooth, pain on biting, lingering temperature pain, swelling, or a lost temporary crown.
What should you ask about saving or replacing this tooth?
Ask whether the tooth is restorable, whether the pulp needs treatment, and whether an onlay, crown, or replacement is most appropriate.
