Teeth are the biggest misconception out there for aging. They can be close but not always exact.Teeth in deer have different desities just like human teeth. Some people get cavities and gum disease easy while others have very good teeth that just don't go bad and both people take care of their teeth the same. With deer it depends where they are, what they eat, and genetics of their teeth. Teeth are a decent indicator but we all know you don't need teeth to age a deer under 3 1/2 years old and when they get olderthan 3 you can usuallly get within a year of theactual age but you can never be sure........... Only way to truely age a deer 100% is to watch it grow upby have pics of it every year or see it from the time its 2 1/2 or 3 1/2. WCL
