my son is 6 yrs 7 months old... so soon 5 teeth has fallen.. I am worried about him...?

A. All four center teeth, known as bottom and top incisors, usually fall out in the 6-8 year range. The sharp teeth beside them (called canines or cuspids) as well as the first molars leave a little later, around 9-12 years old. The second molars are often the last to go … typically in the 10-12 year range.
