Diet and Oral Health: Frequency, Sugars and Everyday Choices
How eating patterns affect the oral environment, and why frequency can matter as much as a single food.
The mouth responds to repeated exposures
Frequent intake of fermentable carbohydrates can repeatedly lower plaque pH. Eating pattern and frequency therefore matter alongside total diet.
What about sugar substitutes?
Non-sugar sweeteners such as xylitol do not behave exactly like fermentable sugars, but claims about cavity prevention should still reflect the evidence.
Keep the big picture
Dietary patterns, fluoride exposure, hygiene, saliva and professional care interact. No single food or supplement determines oral health.
