People should use xylitol even if they use fluoride. Here’s why.

Fluoride and xylitol perform different functions synergistically. Fluoride rebuilds and strengthens the enamel but does nothing to help the cavity-causing bacterial microbiome. This is where xylitol comes in. Hundreds of studies show that xylitol changes the microbiome in the mouth into a healthier state.

This is done through three mechanisms:

1. Inhibiting Bacterial Adhesion: Xylitol inhibits bacterial adhesion, so bacteria can’t stick to gums and oral tissue.
2. Breaking Down Bacterial Biofilm: Xylitol breaks down bacterial biofilms, the colonies where bacteria thrive and multiply.
3. Starving Bad Bacteria: Unlike other sweeteners xylitol doesn’t provide energy to the bacteria in the mouth. However, bacteria still try to consume xylitol, which initiates a process of starving out the bacteria.

The American Academy of Pediatric Dentistry (AAPD) has endorsed xylitol as part of a complete strategy to prevent tooth decay or cavities. Xylitol as an alternative for patients can help them manage recurring cavities easily, and with minimal disruption to their routine. Patients that have dry mouth, are aging, or have undergone oncology treatment will most likely have an acidic pH. These patients, along with those that consume a lot of acidic foods and drinks, such as energy drinks, sports drinks, and sodas, are especially vulnerable to demineralization. Essential minerals are leeched out of enamel when pH is low. This results in white spot lesions, softened enamel, and decay. Research suggests that five minutes of exposure to a 100% xylitol-sweetened product will neutralize acids and bring the pH back to a normal level more quickly than if left on its own.

Some parents think that oral care isn’t as important in the early years of a child’s life because the baby teeth will fall out. This can lead to a lifetime of healthy or unhealthy teeth and gums. Studies show that using xylitol in a child’s life will have long-lasting effects by decreasing cavity-causing bacteria in the mouth.
