Teething Timetable

When new teeth appear

(HealthDayNews) -- When babies grow new teeth, the infants usually become overly cranky. So at what age can you expect this behavior? Well, there are 20 primary teeth -- 10 on top and 10 on the bottom -- and they come in at different ages for different kids. The St. Louis Children's Hospital has outlined a typical pattern of appearance:

  • Central incisors (upper and lower front teeth): 5-8 months
  • Lateral incisors (next to front teeth): 7-10 months
  • First molars: 12-16 months
  • Cuspids (eye teeth): 14-20 months
  • Second molars: 20-32 months
