Is Vitamin D Good for Oral Health? The Science Behind a Healthy Smile

Strong teeth aren’t just about brushing, they start with vitamin D. So, is vitamin D good for oral health? Absolutely. Vitamin D helps your body absorb calcium, directly strengthening tooth enamel and jawbone. Research shows that people with low vitamin D levels are over twice as likely to have dental caries (cavities) and experience more gingivitis.



What Science Says: Is Vitamin D Good for Oral Health?

• Prevents Cavities: Studies link vitamin D deficiency to a 2x higher risk of tooth decay.
  
  
• Boosts Gum Health: Higher vitamin D levels mean less gum inflammation and lower risk for periodontitis.
  
  
• Supports Strong Teeth & Bone: Vitamin D ensures your body absorbs calcium and phosphorus for resilient teeth.
  
  
• Hard Stats: National data finds about 33% of people with low vitamin D have untreated dental caries.
