Your daughter is 9 years old and her bottom left canine tooth loose Is that baby tooth?

It is likely that your daughter's loose bottom left canine tooth is a baby tooth. Baby teeth, also known as primary teeth or deciduous teeth, start to fall out and are replaced by permanent teeth at around 6-7 years of age. The average age for a child to lose their canine teeth is 9-12 years old, so it is within the normal range for your daughter to be losing her bottom left canine tooth at 9 years old. The permanent canine teeth that will replace the baby teeth usually start to erupt within a few weeks to months after the baby teeth fall out. If you have any concerns or questions about your daughter's teeth, it is recommended to consult with a dentist or dental professional who can provide a proper diagnosis and treatment plan.
