Vitamin D deficiency has been increasingly associated with multiple oral health conditions in scientific and clinical research. Evidence suggests that low vitamin D levels may contribute to enamel defects, higher cavity risk, periodontal disease, impaired bone support around teeth, and delayed healing after dental treatments.
Vitamin D plays an essential role in calcium metabolism, tooth mineralization, immune regulation, and inflammatory control within the oral cavity. When levels are inadequate, the body’s ability to maintain strong teeth and healthy gums may be compromised.
Researchers have observed that individuals with vitamin D deficiency may have a greater susceptibility to dental caries and gum disease, highlighting the important connection between nutritional health and oral health.
Maintaining healthy vitamin D levels through safe sunlight exposure, diet, and medical guidance may support both oral and overall health.
