The widely held notion suggests that consuming certain fruits, specifically crisp varieties, may contribute to oral hygiene through mechanical action. The chewing process, particularly when involving textured foods, can stimulate saliva production, a natural cleansing agent within the oral cavity. This increase in salivary flow aids in neutralizing acids and washing away food particles.
The potential benefit lies in its accessibility and natural appeal as an addition to, not a replacement for, standard oral care practices. Throughout history, the emphasis on mechanical oral hygiene has been a constant, evolving from rudimentary methods to sophisticated tools. The inclusion of firm fruits in the diet presents a palatable and readily available adjunct to established routines.
