Permanent teeth will start coming in around 12–16 weeks, and puppies will eventually end up with 42 permanent teeth. The process of teething is painful to puppies much like babies.
Maxillary canines begin to calcify by 4 months of age. The enamel of the tooth is completely formed by around 6 to 7 years of age and the permanent maxillary canines erupt at around 11 to 12 years of age. The root is completely formed by 13 to 15 years of age. The maxillary canine teeth are slightly wider than the mandibular canine teeth.
