What is the role of oral probiotics (Lactobacillus reuteri) and nutrition in optimizing oral flora?

The oral cavity is a complex ecosystem where billions of good and bad bacteria live in balance. Traditional alcohol-based mouthwashes kill all the good and bad bacteria in the mouth, disrupting this delicate balance (dysbiosis) and leading to fungal infections and the growth of more aggressive caries-causing agents. Holistic dentistry aims to protect the oral flora not by killing it, but by increasing the number of good bacteria. For this purpose, special “Oral Probiotics” containing Lactobacillus reuteri (prodentis, etc.) strains are used. These good bacteria adhere to the tooth surfaces and gums, preventing the growth of caries-causing Streptococcus mutans bacteria and plaque formation. In terms of diet, refined sugars and acidic foods are eliminated to keep the oral environment alkaline; fibrous vegetables and fermented foods continuously nourish the good oral flora.
