Before talking about sicknesses cats can suffer in their teeth and what their dental hygiene should look like, we are going to explain feline dental development to you.
At birth, cats do not have teeth. The appearance of the first begins around day 15 after birth and all the temporary teeth, the baby teeth, will be complete in the 8th week. But not all teeth come in at the same time. It depends on the type.
Primary Teeth (baby teeth)
The incisors (the teeth in the front of the mouth) appear between the 2nd and the 4th week of life.
The canines (fangs) appear between the 3rd and 5th week.
The last baby teeth that come up for kittens are the premolars, which come up between the 3rd and 8th week.
Therefore, after the 8th week of life, the cat’s oral composition is the following:
Lower jaw: 2 canines (1 right/1 left), 6 incisors (3 right/3 left), and 4 premolars (2 right/2 left).
Upper jaw: Only the number of premolars changes (3 right/3 left). The number of canines and incisors is the same.
Secondary Teeth (permanent teeth)
Permanent teeth start to come in at 12 weeks and are complete after 21 weeks.
The incisors start to appear between the 3rd and 4th month.
The canines between 4 and 5 months.
The premolars come up between the 4th and 6th month.
And, different from the baby teeth stages, molar teeth now appear between the 4th and 5th month.
After 6 months, your cat’s dental composition will be:
2 upper canines (1 right/1 left)
6 upper premolars (3 right/3 left)
6 upper incisors (3 right/3 left)
2 molars (1 right/1 left).
