Permanent teeth start coming in at around age six and continue until age 17 to 21.
When you take out you're tooth twice they become permanent teeth you only lose your teeth once. your baby teeth fall out, and the adult ones come in. this doesn't happen twice.
Baby teeth have no nerves or "feet" like permanent teeth, so when they come out, it's just the tooth.
This is just a genetic thing that happens while they are forming in the womb. Congenitally missing teeth can mean they will miss the permanent teeth , also. An orthodontist will help once their permanent teeth come in..
the permanent layer of teeth starts erupting from 6-7 years of age
nah, im 13 and my permanent teeth came in ages ago -.- :D x
None, though you are born with the "buds" for all of them. Around week 6 of gestation you develop the buds for baby teeth, and around the 20th week, you develop the buds for permanent teeth. If the teeth buds do not form at these times, chances are, a person won't have any teeth.
The second permanent molars come in around the ages of 12-13. That will give you 28 teeth total, until your wisdom teeth come in
That is possible, but they'll become more steady later on.
