Why haven't the primary teeth fallen out yet?
My 6-year-and-5-month-old daughter has only lost two of her lower front teeth, and both have grown back completely.
I am wondering why the other teeth are still intact and show no signs of loosening or falling out.
Is this phenomenon normal? My older daughter had lost most of her baby teeth by this age.
Why is there such a difference between the two? Thank you.

This is a normal phenomenon.
Typically, primary teeth are replaced gradually between the ages of 6 and 12.
Only the first molars emerge on their own in the mouth, with one on the upper and lower jaw on each side at around age 6.

Your eldest daughter losing all her primary teeth at just over 6 years old may indicate a problem, so it is advisable to have her checked by a dentist.

It's quite common for parents to have concerns about their children's dental development, especially when comparing siblings. In your case, your daughter is 6 years and 5 months old and has only lost two of her baby teeth, while your older daughter had lost most of hers by this age. Let's delve into this situation.
Firstly, the timeline for losing baby teeth can vary significantly from child to child. The typical age range for children to start losing their baby teeth is between 6 and 7 years old, with the first teeth to fall out usually being the lower central incisors. However, some children may start losing their teeth earlier or later than this average range, and that's perfectly normal.
The process of losing baby teeth is influenced by several factors, including genetics, the timing of tooth eruption, and individual growth patterns. If your older daughter lost her teeth earlier, it could simply be a matter of genetic predisposition or individual development. Each child's dental development is unique, and variations in the timing of tooth loss are common.
Regarding your daughter's teeth that have not yet shown signs of loosening, it's important to note that baby teeth are held in place by their roots, which gradually dissolve as the permanent teeth underneath begin to emerge. If the roots of the baby teeth are still intact and the permanent teeth have not yet started to push against them, the baby teeth will remain stable. This can lead to a situation where some children may have baby teeth that stay in place longer than others.
In terms of dental health, as long as your daughter is maintaining good oral hygiene and there are no signs of decay or other dental issues, there is typically no cause for concern. Regular dental check-ups are essential, as a dentist can monitor the development of her teeth and ensure that everything is progressing as it should. If there are any concerns about the alignment of her teeth or the timing of her tooth loss, a dentist can provide guidance and, if necessary, suggest interventions.
It's also worth mentioning that some children may experience a delay in losing their baby teeth due to factors such as nutrition, overall health, or even the presence of dental crowding. If your daughter has a healthy diet and is free from any dental issues, these factors are less likely to be a concern.
In conclusion, the differences in tooth loss between your daughters are likely due to normal variations in dental development. As your daughter approaches the typical age for losing more baby teeth, you may start to see changes. If you have any ongoing concerns, I recommend scheduling a dental appointment for her. A pediatric dentist can provide reassurance and ensure that her dental development is on track. Remember, every child is unique, and variations in dental timelines are part of their individual growth journey.
