My child's baby tooth just refuses to drop even though all the other teeth have changed, what should I do??

Kids start losing teeth when they are 6 and lose about 8 teeth (8 front top and bottom) in the 1st 2 years. There's then a 'break' of two years and teeth start loosening and falling out again at 10. So perhaps your kid is at the 8 year mark and his teeth are taking a 'break'!
