What is the Difference Between Maxillary and Mandibular Canine?

The main differences between maxillary and mandibular canines are found in their location, shape, and root structure. Here are the key differences:

1. Location: Maxillary canines are found in the upper jaw between the maxillary lateral incisors and premolars, while mandibular canines are found in the lower jaw between the mandibular lateral incisors and premolars.
2. Shape: The labial surface of a mandibular canine is more smooth and convex, without a central lingual ridge. In contrast, the maxillary canine has a central strengthening ridge extending from the cingulum to the cusp. The maxillary canine root is longer and stronger than the mandibular canine root.
3. Crown and Root Length: The crown of the maxillary canine is thicker and wider than the mandibular canine. Both maxillary and mandibular canines have one long root, but sometimes the mandibular canine can be bifurcated into two roots.
4. Eruption Age: The permanent maxillary canine usually erupts around the age of 11-12, while the permanent mandibular canine erupts around the age of 9-10.
5. Root Development: The roots of maxillary canines are completely developed around 13 to 15 years of age, while the roots of mandibular canines are completely formed by the age of 13.

Comparative Table: Maxillary vs Mandibular Canine

The maxillary and mandibular canines are two types of teeth that play an important role in dental anatomy and physiology. They are known as the "cornerstones of the dental arches" and are used for ripping and tearing food during the mastication process. Here is a table comparing their differences:

Both types of canines assist the incisors in the mastication process and are located in the four corners of the mouth, next to the lateral incisors.
