    A fawn will only have 3 or 4 teeth.
    A yearling can have 5 or 6 depending on when they were born. Early birth having 6 and late birth having 5. The telltale signage tooth is the 3rd tooth back. It is called the milk tooth. At birth this tooth has a 3 cusp crown to it and usually is in place until around 1 1/2 years old. It is however replaced at two years old with a 2 cusp crowned tooth. At 2 1/2 years old the 6th tooth will be fully emerged. On anything younger that 6th tooth will not be fully emerged. At 3 years old all teeth are perminent teeth and dentine wear and cusp wear is what you have to have knowledge of to determine age by teeth.

    It is likely you are not dealing with 3 year old deer. The number of teeth present say differently. Hope that helps. Tim

    Helpful too http://bowsite.com/BOWSITE/features/articles/deer/aging/
    It has to be a older fawn, at a year and a half or so they should have all 6 teeth

    EastonWest What we do in North Dakota, STAYS here.

    5 teeth means its under a year and a half of age. at 1 1/2 years, they will have 6 teeth with the front one being a tri-cuspid. At 2 1/2 years this tooth will have fallen out and been replaced by a bi-cuspid. After this aging them starts to get a little more difficult.
     
  8. Hey Tim.. Question for ya..

    Can you accurately age deer by the mature teeth/wear on the incisors like you can sheep/goats/cows? Just curious...

    Yes Shelby you can up to a point. After 6.5 years it gets very difficult.

    tschuppan, it does appear that you do have an oddity there. In your second picture it is obvious that there are only 5 teeth present and the third(milk) tooth is a two cuspid permanent tooth. As with every rule, there are those expections. This is where ring analysis takes over.
