This natural ingredient will help neutralize acid and effectively prevent tooth decay.

Tooth decay is a common global health problem, formed when bacteria break down sugar and release acids that erode tooth enamel. However, recent research has shown that arginine – a naturally occurring amino acid in saliva – is key to restoring balance and protecting your smile.

 

Arginine's mechanism for protecting teeth: Neutralizing harmful acids.

Bacteria in the mouth don't exist in isolation but form dental biofilms that adhere tightly to the teeth. Here, acid production occurs continuously. Arginine acts as "fuel" for these beneficial bacteria, which possess the Arginine Deiminase (ADS) system.

This system converts arginine into alkaline compounds, which directly neutralize harmful acids, thereby raising the pH level in the oral cavity and protecting tooth enamel from erosion.

 

A study from Aarhus University (Denmark), published in the International Journal of Oral Science, conducted a direct experiment on 12 volunteers with tooth decay. The results showed that:

Reduced acidity: Using the pH indicator "C-SNARF-4", scientists confirmed that plaque treated with Arginine had significantly higher pH levels (less acidic) after 10 and 35 minutes of exposure to sugar.

Plaque restructuring: Arginine reduces carbohydrate components such as fucose and galactose. This breaks down "acid pockets" in biofilms, making plaque less toxic and limiting acid buildup near tooth surfaces.

Microbiome shift: Advantage for beneficial bacteria

Through 16S rRNA gene sequencing, research has discovered that arginine is creating a "revolution" in microorganisms:

There was a significant reduction in the Streptococci mitis/oralis group of bacteria (a group that specializes in acid production but lacks the ability to produce alkalinity).

It promotes the growth of bacteria species that are more capable of metabolizing arginine.

This shift not only reduces the aggressiveness of plaque but also builds a healthy and sustainable oral ecosystem.

A safe solution for all ages.

Because arginine is a naturally occurring amino acid found in the body and many food proteins, it is extremely safe for both adults and children. Experts recommend adding arginine to daily care products such as toothpaste or mouthwash to protect those prone to cavities.
