Canine tooth

Canine tooth or canines are the pointed, conical teeth found in the dental arch of both primary (deciduous) and permanent dentitions. They are also known as cuspids or eye teeth due to their position under the eyes.

Anatomy

The canine teeth are situated at the 'corners' of the dental arches. They have a sharp, pointed biting surface. Their main function is to grip and tear food. The upper canines are larger and longer than the lower canines.

Development

In humans, the primary upper canines erupt around the age of 16-22 months, while the primary lower canines erupt approximately between 17-23 months. The permanent upper canines replace the primary ones at around 11-12 years of age, and the lower ones at 9-10 years.

Function

The primary function of the canine teeth is to hold, grasp, and tear food. They are essential for maintaining the bite alignment. They also play a significant role in the facial appearance and speech.

Canine teeth in animals

In many animals, the size and shape of the canine teeth vary widely between species. They are often greatly enlarged in carnivores and omnivores, where they are used primarily for killing prey and for fighting.

Dental health

Maintaining the health of the canine teeth is important as they are essential for proper biting and chewing. Regular dental check-ups, brushing, and flossing can help keep these teeth healthy.
