7-8yo
When do Permanent mandibular Central Incisors erupt?
6-7yo
When do Permanent Maxillary Lateral Incisors erupt?
8-9yo
When do Permanent mandibular lateral Incisors erupt?
7-8yo

Primary Dentition - Calcification of all teeth begins during
4th fetal month
Primary Dentition - Formation of Central Incisors is complete at
18-24mo
Same as lateral incisors
FYI: Permanent 1st premolars start calcification at this time
Primary Dentition - Formation of Lateral Incisors is complete at
18-24mo
Same as lateral incisors
FYI: Permanent 1st premolars start calcification at this time
Primary Dentition - Formation of Canines is complete at
30-39mo
This is after formation of primary first molars
Primary Dentition - Formation of Primary 1st molars is complete at
24-30mo
FYI: Also when Permanent 2nd premolars start calcification
Primary Dentition - Formation of Primary 2nd molars is complete at
36mo
Primary Dentition - Eruption of Central Incisors (Max & Mand)
Maxilla: 6-10mo
Mandible: 5-8mo
Primary Dentition - Eruption of Lateral Incisors (Max & Mand)
Maxilla: 8-12mo
Mandible: 7-10mo
Primary Dentition - Canines (Max & Mand)
16-20mo
Same time, but after D’s come in.
Primary Dentition - Primary 1st molars (Max & Mand)
11-18mo
Same time, but before C’s
Primary Dentition - Primary 2nd molars (Max & Mand)
20-30mon
Same time
Last primary tooth in the mouth
Primary Dentition - A 2 year old at 24mon should have which teeth?
ABDC(E)
Recall: E erupts b/w 20-30mo of age
Primary Dentition - A 1 year old at 12 mon should have which teeth?
AB(C)
Recall: Cs erupt at 11-18mo
