The canine is relatively resistant to dental caries and periodontal disease. Its major value lies in its long root, excellent bony support, and characteristic crown shape. These endowments allow it to exert a stabilizing influence on occlusal forces by assuming the major occlusal load during mastication. The highly developed proprioceptive ability of the canine helps protect the remaining teeth and add to the longevity of the dentition.The maxillary canine is perhaps the most variably positioned tooth in the human dentition, a feature important to the orthodontist who often must locate and move it.An impacted canine is usually easy to diagnose but the skill and expertise of the Orthodontist, Oral Surgeon And General Practioner are needed to bring it to its proper position.
