The first teeth to be replaced during dental eruption are the lower central incisors, followed by the upper central incisors. The previous arrangement of the baby teeth will determine the pattern of replacement for the permanent teeth.

It’s important to note that permanent teeth are significantly larger than baby teeth. Therefore, spacing between baby teeth will facilitate the dental eruption of permanent teeth. However, for this to occur correctly, an additional enlargement in the anterior region is necessary to ensure the proper alignment and positioning of all the permanent teeth.

Around a year after the process of tooth replacement begins in children, the permanent lateral incisors erupt. These teeth develop in a more lingual position compared to the central incisors and gradually move forward to erupt beside the central incisors.

In cases where there is a lack of space, the lateral incisors may not position themselves next to the central incisors and instead erupt further back, causing a slight crowding of 1-2 mm. This physiological crowding typically diminishes as the child develops, and the lateral incisors eventually align with the central incisors.

It is important to remember that the tooth replacement process should be monitored by an orthodontist starting from the age of 6, with regular check-ups to detect any abnormalities early.
