Lateral canals are typically found in the apical third of the root. This area is crucial because it serves as the site where the main canal morphologies branch out to connect with small lateral canals. These canals can present challenges during endodontic procedures as they can harbor bacteria and contribute to persistent infections if not adequately cleaned and sealed.

In the apical third, lateral canals often create a network that helps facilitate pressure equalization and nutrition during the tooth's development. Their presence can vary significantly from tooth to tooth, and understanding their common locations aids in successful root canal treatments.

The other areas mentioned, such as the middle of the root or near the furcation area, are not typical locations for lateral canals, as most of the significant branching usually occurs closer to the apex. The first third of the root, while critical for the overall anatomy, does not typically contain these canals in significant numbers or sizes.
