Canine Teeth: Functions in Chewing, Spacing, Esthetics, Speech, and Jaw Guidance

Canines (cuspids/eye teeth) are pointed teeth beside incisors, upper and lower. Key roles:

1. Tearing/cutting: Sharp cusps grip/pierce tough foods (meat, fibrous veg/fruit).
2. Space maintenance: Cornerstones preventing tooth drift.
3. Esthetics: Prominent in smile line.
4. Speech: Aid "f," "v," "th" sounds.
5. Jaw guidance: Prevent overclosure/joint issues.
6. Occlusion/bite: Interdigitate for balanced bite.
7. Eruption timing: Last to erupt (11–13 years), developmental markers.
8. Sexual dimorphism: Often larger in males.

Canines are vital beyond chewing—support spacing, esthetics, speech, jaw function, bite.
