Why would u need a crown
A dental crown covers and strengthens a damaged tooth when a filling cannot restore enough structure for normal function.
The short answer
A crown is a custom-made cap that covers a tooth weakened by decay, a large filling, a crack, or root canal treatment. It restores shape and chewing function when the remaining tooth needs more coverage than a filling provides.
How does a crown stay secured over the prepared tooth?
The crown sits over the prepared enamel and dentine, while a cement layer holds it in place. It can be made from ceramic, zirconia, porcelain fused to metal, or metal, selected according to position, load, appearance, and available tooth structure.
What happens when the dentist prepares a tooth for a crown?
The dentist removes diseased tissue, checks the bite, shapes the tooth, records its form, and fits a temporary crown while the laboratory restoration is made. At the next visit the permanent crown is checked, adjusted, and cemented if the fit and contacts are satisfactory.
When should a damaged or treated tooth be assessed?
Arrange an assessment for a fractured cusp, a very large filling, recurrent decay, or pain after root canal treatment. Prompt review is important if a temporary crown loosens, the tooth hurts on biting, or swelling appears.
What should you ask about alternatives and crown materials?
Ask how much sound tooth remains, whether an onlay or filling could work, and which crown material suits the tooth. Ask how the bite will be checked and what care is needed around the crown margin.
Frequently asked questions
Does every root canal tooth need a crown?
The need depends on tooth position, remaining structure, biting forces, and the restoration that can seal and protect it.
Can a crown fix a cracked tooth?
A crown may brace a crack that is confined to restorable tooth structure, but a crack reaching the root can change the treatment options.
