Baby teeth normally fall out in the same order they came in. The adult teeth take time to travel to their place. When they push against the baby teeth, children’s teeth start loosening.
Kids usually lose the lower central incisors first. This is often followed by their two front teeth, or their upper central incisors. Their upper canines and second molars are often the last to leave.
The primary teeth, or baby teeth, start to fall out around age 6 to 7. This continues until around age 12. By age 21, most people have their full set of 32 permanent teeth.
Early tooth loss usually happens in kids who also got their teeth in early. The opposite is also true. Late tooth loss usually happens in children who got their teeth in late.
