One amino acid, in particular, has been studied for its potential benefits in dental health: arginine. Studies have shown that arginine can help reduce the formation of biofilm on teeth, which is a significant contributor to tooth decay. By reducing biofilm, arginine may help prevent the acid production that leads to cavities.
A key study published in a leading dental journal explored the effects of arginine on dental plaque and saliva. The researchers found that arginine significantly reduced the levels of harmful bacteria in the mouth, which are responsible for cavity formation. This breakthrough finding supports the idea that natural amino acids like arginine could play a crucial role in preventive dental care.
