This confused me. Milk teeth/baby teeth/deciduous teeth are retained
for QUITE some time. The ages below are from Fox's vet text,
_Biology and Diseases of the Ferret_ , and you'll find more detail in
a number of Bob Church's recent posts. Here are a few of the
approximate ages at which some milk teeth are lost and are replaced
(or joined in the case of molars) by adult/permanent teeth.

50 days (about 7 weeks): Canines (upper and lower) and lower Molar 1.

53 days (about 7 and 1/2 weeks): upper Molar 1

60 days (about 8 and 1/2 weeks): upper Premolars 2, 3, & 4, lower Premolar 2

67 days (about 9 and 1/2 weeks): lower Premolar 3

74 days (about 10 and 1/2 weeks): lower Premolar 4, and lower Molar 2

In other words, you can expect one milk tooth to still exist in the
mouths of kits up to an age of around 2 and 1/2 months, and multiples
to still be retained till only about a week before that, on average.

Eye's open at around 5 weeks of age, plus or minus about a half week,
if my memory of what multiple breeders have written serves.
(Breeders, correct me if I am wrong.)
