What is the difference between natal teeth and neonatal teeth in terms of timing of eruption?

Natal teeth are present at birth, while neonatal teeth erupt during the first 30 days of life. Signup and view all the answers

What is the prevailing theory regarding the etiology of premature eruption of natal and neonatal teeth?

What is the most common type of natal and neonatal teeth in terms of dentition affected?

85% of natal and neonatal teeth are mandibular primary incisors. Signup and view all the answers

How are natal and neonatal teeth clinically classified based on their characteristics?

Clinically, these teeth are classified into mature, when fully developed in shape, with a relatively good prognosis, and immature, when their structure and development are incomplete, implying a poorer prognosis. Signup and view all the answers

Why is correct diagnosis of natal and neonatal teeth important for the maintenance of normal dentition?

Premature loss of a primary tooth may cause a loss of space and collapse of the developing mandibular arch, leading to malocclusion in permanent dentition. Signup and view all the answers
