What is the first primary tooth to erupt?

The first primary tooth to erupt is the mandibular central incisor. Typically, this tooth emerges around 6 to 10 months of age in infants. The eruption of primary teeth follows a general pattern, with the lower front teeth generally coming in before those in the upper arch. This early eruption of the mandibular central incisor is significant as it lays the foundation for the child's future dental alignment and oral health.

Understanding the timing of tooth eruption is essential for dental nurses, as it helps monitor the orthodontic development of a child and can flag any potential developmental issues early on. Recognizing that different teeth have different eruption timelines aids in ensuring comprehensive dental care and guidance for parents regarding their child’s oral health.
