A mother is concerned because her 18-month-old toddler has 12 teeth. She is wondering if this is normal for a child of this age. Which is the best response by the nurse?
1) How many teeth did you have at this age?
2) This is a normal number of teeth for an 18 month old.
3) Normally, by age 2 1/2 years, 16 deciduous teeth are expected.
4) All 20 deciduous teeth are expected to erupt by age 4 years.
