A baby tooth, also known as a deciduous tooth or primary tooth, refers to the set of temporary teeth that emerge in the mouths of infants and young children. These teeth typically begin to appear around six months of age and continue to erupt until the age of two or three. Baby teeth serve important functions, such as aiding in chewing, speech development, and providing space for permanent teeth to grow. Over time, they naturally fall out to make way for the eruption of permanent teeth.
