In brief: They become brittle
Endodontically treated teeth become brittle and can fracture because there is no longer a blood supply to nourish the tooth.
After root canal treatment the tooth still has to be restored so it can bear chewing pressure without breaking. A crown is usually the recommended restoration.

In brief: Coronal protection
All root canals done on posterior teeth should be followed up w/ a proper restoration, usually a crown, to protect the tooth.
When the root canal was done, your dentist should explain that to you.

In brief: Non-vital teeth
After root canal the dental pulp whiich nourishes the tooth was completely removed.
The tooth is dead and will become brittle over time. It can fracture easily and that is why a crown is usually recommended after root canal.

In brief: Broken tooth
After root canal treatment a tooth does not have the same feeling as a tooth that still has a nerve.
The mouth looses the ability to control how hard you bite on the tooth, which can lead to increased chance of breaking the tooth. This is why most root canal teeth should have crowns.
