Nutrition and dental caries

Area of Science:

• Dentistry
• Nutrition Science
• Public Health

Background:

• Dental caries management involves dietary practices, fluoride exposure, and oral hygiene.
• Scientific advancements have improved understanding of caries, food supply, and their interactions.
• Fermentable carbohydrates, oral bacteria, and saliva dynamically interact, influencing oral health.

Purpose of the Study:

• To provide dental health professionals with principles for guiding patients on dietary practices to reduce caries risk.
• To integrate general health principles into practical dietary advice for improved oral and general health.
• To promote lifestyle behaviors that enhance oral and overall well-being within clinical practice constraints.

Main Methods:

• Encouraging balanced diets based on moderation and variety (e.g., Food Guide Pyramid, Dietary Guidelines for Americans).
• Advising on food combinations and sequencing to enhance mastication, saliva production, and oral clearance.
• Recommending water for hydration and restricting sweetened beverages to meal/snack times, followed by cariostatic foods (e.g., xylitol gum).

Main Results:

• Dietary advice should focus on 'good' diets and avoid labeling foods as 'bad'.
• Combining food types (dairy with sugary, raw with cooked, protein with acidogenic) aids oral clearance.
• Strategic consumption of cariostatic foods post-meal/snack and adequate hydration are recommended.

Conclusions:

• Dental professionals play a key role in promoting sound dietary practices for caries management.
• Practical dietary guidance should align with general health principles, emphasizing balance, variety, and smart food sequencing.
• Patients with excessive fermentable carbohydrate intake need alternatives for healthy weight, oral health, and nutrient intake.
