Study Notes
Eruption Sequence of Permanent Teeth
- The eruption sequence begins with the Mandibular 1st Molar and Maxillary 1st Molar, both erupting at 6-7 years.
- Mandibular Central Incisor and Mandibular Lateral Incisor follow, erupting also at 6-7 years and 7-8 years respectively.
- Maxillary Central Incisor erupts at 7-8 years, while Maxillary Lateral Incisor erupts at 8-9 years.
- The Mandibular Canine erupts between 9-10 years.
- Both Mandibular 1st Premolar and Maxillary 1st Premolar erupt at 10-11 years.
- The Mandibular 2nd Premolar and Maxillary 2nd Premolar erupt at 11-12 years.
- The Maxillary Canine also erupts at 11-12 years.
- Mandibular 2nd Molar erupts between 11-13 years, while Maxillary 2nd Molar appears between 12-13 years.
- Mandibular 3rd Molar and Maxillary 3rd Molar erupt later, around 17-21 years.
Root and Enamel Formation
- About 50% of a permanent tooth's root formation is complete upon eruption.
- Roots of permanent teeth are fully formed 2-3 years post-eruption.
- The enamel (crown) of a permanent tooth is completely formed 3 years before eruption.
Tooth Eruption Patterns
- Mandibular Canines erupt after the first molars and anterior teeth, but before premolars.
- Maxillary Canines erupt following the first molars, anteriors, and premolar eruption.
- Except for the first molars, mandibular teeth follow a perfect anterior to posterior eruption pattern.
