What deficiency is linked to rickets and tooth decay?

The deficiency linked to rickets and tooth decay is vitamin D. Vitamin D plays a critical role in the body by helping to regulate calcium and phosphorus levels, which are vital for maintaining healthy bones and teeth. When there is a deficiency of vitamin D, it can lead to insufficient calcium absorption, resulting in rickets in children, which is characterized by weakened and softened bones. This can manifest as bone deformities and growth issues. Additionally, low levels of vitamin D can negatively affect dental health, leading to tooth decay since calcium is essential for strong teeth as well.

Thus, maintaining adequate vitamin D levels is essential for both skeletal health and dental health.
