*Śukranīti* demarcates infancy from middle age with replacement of naval teeth. Horses have six lower incisors. In the first year, their colour is milky white, which turns muddy in second year. In the third, fourth and fifth years respectively, central, lateral and corner pairs get replaced by permanent teeth. With advancing age, permanent teeth acquire dots, whose colour changes in order from Black (*Kālikā*), Yellow (*Hārini*), White (*Śukla*), Glassy (*Kaśa*) to Honey or Chocolate (*Makṣika*). Finally, Conchshell holes (*Saṅkha*) appear followed by final shedding.
