Not every root-treated tooth needs a crown . The appropriate solution depends mainly on how much healthy tooth structure remains, which tooth is involved and the forces it receives during chewing.
The root filling seals the root canals. This does not necessarily mean the upper part of the tooth has been restored: a permanent filling , onlay or crown may still be needed. These seal and rebuild the damaged part of the tooth and, where necessary, protect the remaining walls.
If little tooth structure remains, a simple filling may not provide sufficient protection against fracture. In other cases, a full crown is unnecessary and more natural tooth structure can be preserved.
When discussing your treatment plan, we will explain why we recommend a particular restoration. Do not delay definitive treatment just because the tooth no longer hurts: a pain-free tooth can still fracture.
