Is it normal for children to lose teeth at the age of five?

If the front incisors, about five years old tooth loss is also a normal phenomenon, especially in girls, corresponding to a year earlier than boys. If the back deciduous molars show loss, then this age group tooth loss is not normal, because the back teeth can not be replaced until the age of 12 or 13. If the deciduous molars show early loss, it will cause the lower permanent teeth to lose their induction surface when they erupt, showing irregular teeth or crowded teeth. If deciduous molars are missing at five years old, space maintenance should be performed as early as possible.
