Canines are characterized by having how many roots?

Canines are characterized by having a single root. This anatomical feature is significant because it allows for strong anchorage of the tooth in the alveolar bone, which is important for their role in the dental arch. Canines, or cuspids, play a crucial role in the dental occlusion and facilitate the shearing of food due to their pointed cusp.

The presence of a single root makes canines unique compared to other types of teeth, such as molars which typically have multiple roots for stability and support due to their functions in grinding food. Understanding the anatomy of canines is essential in dental nursing, particularly when assessing the health and structure of teeth, planning for restorative procedures, or understanding the implications of tooth extractions.
