Teeth are biological markers of maturity, and their eruption into the oral cavity is an essential milestone in an individual's life. Multiple factors have been considered to play a role in the pattern of tooth eruption, including dental caries, fluorides and congenital conditions such as Down's syndrome. The aim of the paper was to determine the time of eruption of permanent teeth amongst children aged between five and ten years, visiting the Dental College in Mangalore. A survey was conducted among children aged between 5 to 10 years visiting A.B. Shetty Memorial Institute of Dental Sciences Deralakatte, Mangalore. Each child included in the study was screened by clinical examination for the erupted and erupting permanent teeth. A parent/guardian accompanying a child was interviewed and their data were recorded. The study revealed that the first tooth to erupt was the left mandibular first molar, with a mean age of eruption at 6.4 years. A slight early eruption of teeth was noticed in the left side of the jaw compared to the right side in the present study. The first permanent tooth to erupt in the oral cavity is the left mandibular first molar and there is a slight delay in the eruption of the maxillary lateral incisor in the study population.
