Study Notes
Eruption Sequence of Primary Teeth
- Primary teeth eruption follows a specific sequence, starting with mandibular centrals and ending with maxillary second molars.
- The general eruption order is as follows:
- Mandibular Centrals, Mandibular Laterals, Maxillary Centrals, Maxillary Laterals, Mandibular 1st Molar, Maxillary 1st Molar, Mandibular Canine, Maxillary Canine, Mandibular 2nd Molar, Maxillary 2nd Molar.
Eruption Timeline
- Mandibular Centrals typically erupt at around 6 months.
- Mandibular Laterals erupt at approximately 7 months.
- Maxillary Centrals appear at about 7.5 months.
- Maxillary Laterals emerge around 9 months.
- Mandibular 1st Molars show up at approximately 12 months.
- Maxillary 1st Molars erupt at around 14 months.
- Mandibular Canines usually appear at about 16 months.
- Maxillary Canines emerge at around 19 months.
- Mandibular 2nd Molars erupt at approximately 20 months.
- Maxillary 2nd Molars are the last primary teeth to erupt, typically at 24 months.
Eruption Characteristics
- Canines erupt after the first molars but before the second molars within primary dentition, highlighting their unique timing.
- The crown of baby teeth is fully formed prior to eruption, ensuring readiness for emergence.
- The roots of primary teeth complete their formation approximately one year after their eruption.
- Root resorption of primary teeth begins one year after root development is complete, marking a transitional phase for dental development.
General Eruption Pattern
- Deciduous teeth normally erupt from anterior (front) to posterior (back) in the mouth, with the exception of canines, which erupt after the first molars in each quadrant.
