permanent teeth

Temporary teeth appear in three characteristic stages. During the first one the incisors erupt, followed by the first molars (first temporary molar/chart), the canine teeth and afterwards the secondary molars erupt (second temporary molar/chart).

· the mandibular central incisor appears between the 6 to 10 months interval (approximately at 8 months)
· the maxillary central incisor appears between the 7 to 11 months interval (approximately at 10 months)
· the maxillary lateral incisor appears between the 11 to 13 months interval (approximately at 11 months) · the mandibular lateral incisor appears during the 12 to 15 months interval (approximately at 13 months)

The first molar erupts during the 15 to 17 months interval (at approximately 1 year and 4 months)
· the canine erupts during the 19 to 22 months interval (1 year and 7 months or 1 year and 8 months)
· the mandibular second molars erupt at approximately 2 years and 3 months
· the maxillary second molars erupt at 2 years and 3 or 5 months.
The normal tooth eruption interval is generally between the 4th and 10th month for the first tooth and between 1 year and 8 months or 3 years for the last tooth. There are situations of precociously erupted teeth when the first tooth appears before 4 months and the last one before turning 2 years.
Permanent teething develops in two stages. The first one starts around the age of 6 and ends at about 9 years old. The mandibular first molars appear at about the age of 6-7, followed by maxillary first molars and the mandibular central incisors (chart):
