How long does it take for the upper incisors to grow out?

A lost upper incisor usually grows back between 6 months and 1 year.

Each child develops at a different rate, which can affect the time it takes for new teeth to erupt. Some children may grow new teeth faster, while others take a relatively long time. The health of the gums is also important. Inflammation or other abnormalities in the gums may prevent new teeth from erupting, resulting in a delay in eruption. In addition, genetics play a role in tooth growth and development. Children may also be genetically affected if there are family members with late tooth eruption. Not only that, but a child's nutritional intake is critical for tooth development. Lack of key nutrients such as calcium and phosphorus may affect the growth and eruption rate of new teeth.
