Lower secondary canine tooth at a glance
- What it is
- The permanent lower canine, a pointed single-cusped tooth at the corner of the lower dental arch.
- Location
- It lies in the lower dental arch, lateral to the lateral incisor, at the corner of the arch.
- Function
- It tears and grips food.
- Body system
- Digestive · paired (left and right)
- FMA ID
- FMA55687 (Foundational Model of Anatomy)
Key facts
- Typical eruption age: about 9 to 10 years.
- FDI notation: 33 (left) and 43 (right).
- It has a single long root, occasionally divided, and a pointed cusp used to grip food.
- Its pulp and periodontium are supplied by the inferior alveolar nerve (CN V3), so an inferior alveolar nerve block numbs the lower teeth on that side.
Clinical relevance
Dental caries and periodontal disease are the main causes of tooth loss.
