Brown spots on teeth can be caused by a variety of factors, including poor oral hygiene, fluorosis, trauma, or certain foods and drinks. In some cases, vitamin defects—especially vitamin D—can play a role in tooth staining and enamel defects. 

How Vitamin D Affects Teeth

If you are poor in vitamin D, your teeth may not develop properly or may not maintain their strength. This can result in: 

  • Weak enamel 
  • Increased attenuation risk 

Enamel development defects can appear as brown or white spots. 

Do Other Vitamin Functions Work in the Teeth?

Yes. Vitamin D is most directly connected to enamel development and mineralization, but other vitamin deficiencies can also affect oral health: 

  • Vitamin C: The lack of it can affect tooth stability but usually does not directly cause brown spots. 
  • Vitamin A: Important for saliva production and tissue repair. Its deficiency results in a dry mouth and increases plaque cultivation. 
  • Calcium (not a vitamin, but a mineral): Low calcium levels cause weaker enamel and make it more sensitive to discoloration and decay. 

Conclusion

Vitamin D deficiency can contribute to brown spots on teeth due to the weakening of tooth enamel, but that is not the only cause. Maintaining a balanced diet, excellent oral hygiene, and regular dental examinations are the best ways to keep your smile healthy and bright.
