Nutrition and Oral Health

Key Points

  • A bidirectional relationship exists between oral health and diet and nutrition. Diet and nutrition affect the health of the tissues in the mouth; and the health of the mouth affects nutrients consumed.
  • The consumption of sugars has been associated with an increased risk of developing dental caries.
  • The complex nature of periodontal disease makes it difficult to determine its relationship with diet and nutrition.
  • Frequent consumption of acidic food and beverages is associated with an increased risk of erosive tooth wear.
