Understanding primary teeth
Primary teeth, also called baby teeth or deciduous teeth, play a crucial role in a child's development. These tiny teeth pave the way for proper speech, chewing, and the eventual eruption of permanent teeth. Understanding when a baby's teeth fall out, shed, and are replaced by adult teeth is essential for healthcare practitioners and parents to facilitate early prevention and early intervention of dental problems (Nowak & Casamassimo, 2002).
A child's baby teeth begin to fall out around age 6, making way for (larger) permanent teeth. The shedding order generally follows the eruption pattern, with the lower central incisors being the first tooth to fall out, followed by the upper central incisors. Most children have permanent teeth by age 12 or 13, except wisdom teeth, which may erupt later in adolescence or early adulthood.
A baby tooth erupts following a specific timeline, although slight variations exist among children. A tooth eruption chart typically shows the following ages:
- Upper and lower central incisors: Around 6-12 months of age
- Upper and lower lateral incisors: Around 9-16 months of age
- Upper and lower first molars: Around 13-19 months of age
- Upper and lower canines: Around 16-23 months of age
- Upper and lower second molars: Around 23-33 months of age
When baby teeth emerge, children may experience various teething symptoms, including drooling, irritability, gum rubbing, decreased appetite, and a rash around the mouth area (Verma et al., 2017).
