When do a cat’s front teeth grow in fully?

Kittens generally grow incisors at about two weeks and have them fully grown by around four weeks. The baby teeth are basically complete at 4-5 months, totaling 26.

Cats enter the teething stage at 4-5 months, so owners should watch dental development to prevent poor growth. The permanent teeth total 30: upper jaw 6 incisors, 6 premolars, 2 canines, 2 molars; lower jaw 6 incisors, 6 premolars, 2 molars, 2 canines.
