Which baby teeth are supposed to fall out? please answer as soon as possible. thanks alot!

All of them: Unless your child is missing some of his or her teeth, he/she should have lost the last baby tooth by age 11 or when the upper eye teeth come in. If some permanent teeth are missing (very common), the baby teeth may stay in the mouth for many years.

All of them: Over the course of a child's growing years and up to approximately 13 to 14 years old, the primary teeth are sequentially lost as the secondary teeth erupt.

20: All 20 baby teeth, the first 5, starting at the midline and going back, in each quarter of the mouth, between about ages 6 to 12. If you are unsure of what's happening, see a General Dentist, Pediatric Dental specialist, or Orthodontic specialist for a dent-facial developmental examination.
