What age most do kids lose their milk teeth?

Ages 6-12. Although timing can vary, the 20 baby teeth usually begin shedding at age 6-7 and the process goes on until ages 11-14. A wonderful 7th birthday present would be to take your child to an orthodontist who can monitor their growth and development to assure the process goes well.
Age 10 to 12 years. Last set of baby teeth to be lost are the second molars that come in around two to three years of age.
