ANATOMY

Detailed explanation-1: -The first permanent teeth that emerge in the oral cavity are the maxillary and mandibular first molars at around six years of age (six-year molars). They erupt distally to the deciduous second molars. Their eruption is accompanied by or preceded by the exfoliation of the deciduous mandibular central incisors.

Detailed explanation-2: -The mandibular first molar or six-year molar is the tooth located distally (away from the midline of the face) from both the mandibular second premolars of the mouth but mesial (toward the midline of the face) from both mandibular second molars.

Detailed explanation-3: -The first teeth to erupt are the lower and upper central incisors, which erupt between the ages of 6 12 months. The next to erupt are the lateral incisors between 9-16 months, followed by the first molars from 13-19 months. Next, the cuspids (canines) erupt from 16-23 months.

Detailed explanation-4: -first molars (back teeth) – these come through at around 12 to 16 months. canines (between the lateral incisors and the first molars) – these come through at around 16 to 20 months. second molars – these come through at around 20 to 30 months.
