Tooth eruption may be the underlying cause of recent-onset crying episodes, restlessness and fever in your baby.

What you should know about tooth eruption periods

Does your baby become bad-tempered when s/he is 6 months old? S/he cries too much and sleeps restless? If you also notice fever, it means sleepless nights for parents. You may possibly face the major challenges as of five months after the birth of your baby. Because, your baby will start erupting teeth as of 6 months. Although tooth eruption is a source of restlessness, it also indicates that your baby is growing.

How long does tooth eruption stage last?

Milk teeth start erupting when your baby is six to eight months old. Tooth eruption ceases when the baby is 2.5 to 3 years old, after 20 teeth erupt (10 teeth in lower jaw and 10 teeth in upper jaw). Complaints of your baby can be relieved by teethers that are hardened in the fridge in the tooth eruption stage.

How about the time table for teeth eruption?

Timetable for eruption and loss of primary teeth is as follows:

Teeth of lower jaw

  • First primary incisor: Erupts at 6 to 10 months of age and falls out when 6 to 7 years old.
  • Second primary incisor: Erupts at 10 to 16 months of age and falls out when 7 to 8 years old.
  • Primary canine: Erupts at 17 to 23 months of age and falls out when 9 to 12 years old.
  • First primary molar: Erupts at 14 to 18 months of age and falls out when 9 to 11 years old.
  • Second primary molar: Erupts at 23 to 31 months of age and falls out when 10 to 12 years old.

 

Teeth of upper jaw

  • First primary incisor: Erupts at 8 to 12 months of age and falls out when 6 to 7 years old.
  • Second primary incisor: Erupts at 9 to 13 months of age and falls out when 7 to 8 years old.
  • Primary canine: Erupts at 16 to 22 months of age and falls out when 0 to 12 years old.
  • First primary molar: Erupts at 13 to 19 months of age and falls out when 9 to 11 years old.
  • Second primary molar: Erupts at 25 to 33 months of age and falls out when 10 to 12 years old.

Primary teeth start erupting in babyhood and they stay in the month up to 12 years of age; primary teeth play a very significant role both in dental and overall health. Children enter in mixed dentition stage as of 6 years of age. First molar erupts at 6 years of age followed by incisors at 7 to 8 years of age, first molars and canines at 9 to 11 years of age and second molar when 12 years old. Tooth eruption stage ends when the teeth fall out at 12 years of age. Primary teeth are more vulnerable to caries and therefore, you may notice caries in mouth of your child in tooth eruption stage. Moreover, teeth may break in the tooth eruption stage.
