1.1 Describe the morphology, eruption dates and function
Primary dentition
These are the first teeth the erupts into oral cavity and comprises of 20 teeth. Many times,
such teeth are also named as deciduous teeth (Balaji, 2016). These teeth exfoliate ones the
permanent teeth erupt. These teeth are important for the development of mouth. They also
maintain arch length within the jaw. They also provide guidance to for eruption path of the
permanent teeth.
Tooth Eruption Date
(Avg.)
Maxillary
Central Incisor 8-12 Months
Lateral Incisor 9-13 Months
Canine 16-22 Months
1st Molar 13-19 Months
2nd Molar 25-33 Months
Mandibular
Central Incisor 6-10 Months
Lateral Incisor 10-16 Months
Canine 17-23 Months
1st Molar 14-18 Months
2nd Molar 22-31 Months
Secondary dentition
It is also called as permanent dentition and comprises of 32 teeth. There are 16 teeth in the
maxilla and 16 in the mandible. Their main function is to grip and tear food. These teeth also
help in tearing, biting and chewing the food.
