How many teeth should a 12 year child have?
Well my daughter is 12 years old So i just recently counted her teeth and she had about 28-30 teeth.
There is no set number of teeth a person looses a year. In general it's safe to say a child looses from 1-3 teeth a year. Though, some get teeth later than the norm and some earlier so if they were late on getting teeth they could be loosing a lot more than 1-3 teeth when they're nine. Hope this helped.
