Children's Tooth Replacement: Deep Roots and Calcium Concerns - Dentistry

Children's tooth replacement with non-resorbed roots?


Hello, doctor.
My child has currently lost 4 teeth, and each time a new tooth has emerged before the old one was removed; none of the teeth were loose.
When the teeth were extracted, the doctor mentioned that the roots were very deep and had not been resorbed.
Could this indicate that my child has a calcium deficiency? Does the lack of root resorption mean that the teeth are more prone to cavities? Thank you for taking the time to respond.

Hello: There are many reasons for the non-resorption of primary tooth roots, including environmental factors and genetics.
If this situation occurs, it is important for you to regularly visit a healthcare facility for check-ups to prevent misalignment during the transition to permanent teeth.
Thank you, and wishing you peace and good health.

When it comes to children's dental health, particularly regarding the replacement of primary teeth (often referred to as baby teeth or milk teeth), there are several factors to consider. The situation you've described, where your child has had four teeth replaced without any noticeable looseness and with deep roots that have not been resorbed, raises important questions about dental development and potential underlying issues.

Firstly, it's essential to understand that the process of losing primary teeth is a natural part of dental development. Typically, primary teeth begin to loosen as the permanent teeth develop beneath them, leading to the resorption of the roots of the primary teeth. This resorption is a normal physiological process that allows for the primary teeth to be replaced by the permanent ones. If the roots of the primary teeth are not resorbed, it does not necessarily indicate a calcium deficiency in your child. Instead, it could be attributed to various factors, including genetics, the timing of tooth eruption, and individual variations in dental development.

Calcium plays a crucial role in the overall health of teeth and bones, but the presence of deep roots that have not been resorbed does not directly correlate with a deficiency in calcium. Other factors, such as the child's diet, oral hygiene practices, and overall health, can also influence dental health. If there are concerns about calcium intake, it may be beneficial to consult with a pediatrician or a nutritionist to ensure that your child is receiving adequate nutrients for healthy dental development.

Regarding the concern that deep roots and lack of resorption may lead to an increased risk of cavities (caries), it is important to note that the risk of cavities is primarily influenced by factors such as oral hygiene, diet, and the presence of fluoride. If your child maintains good oral hygiene practices—such as regular brushing with fluoride toothpaste, flossing, and limiting sugary snacks—the likelihood of developing cavities is significantly reduced, regardless of the status of the primary tooth roots.

In summary, while the situation you described may seem concerning, it is not uncommon for children to have primary teeth with deep roots that have not been resorbed. This does not inherently indicate a calcium deficiency or an increased risk of cavities. However, it is always advisable to maintain regular dental check-ups to monitor your child's dental development and address any potential issues early on. If you have ongoing concerns about your child's dental health, consider seeking a consultation with a pediatric dentist who specializes in children's dental care. They can provide tailored advice and treatment options based on your child's specific needs and circumstances.
