Xylitol & Fluoride

Xylitol and fluoride both are anti-cavity but they have “Synergistic therapy effect” when combined together.

Means the combination of fluoride and xylitol inhibit acid production more effectively than fluoride or xylitol alone. This is called “Synergistic effect.”

According to a 2005 study, fluoride and xylitol together have synergistic inhibitory effects on the acid production of cavity causing bacteria (mutans streptococci). The study also suggests that xylitol can enhance the inhibitory effects of low concentrations of fluoride. 

A combination of xylitol and fluoride can help prevent cavities and make teeth stronger. Both xylitol and fluoride are widely used as cariostatic agents. Cariostatic agents are used to treat and prevent dental cavities. Cariostatic means inhibiting the formation of dental caries. 

Dental Health benefits of Xylitol & Fluoride

Xylitol helps protect teeth from damage, and fluoride helps repair any damage that the teeth might sustain. Fluoride strengthens tooth enamel and helps repair early stages of tooth decay, while xylitol inhibits the growth of cavity-causing bacteria and reduces acid production in the mouth.

Both xylitol and fluoride work together to:
Inhibit Cavity causing Bacteria
Both xylitol and fluoride inhibit the growth of cavity causing bacteria (streptococci mutans) thus inhibiting the acid production.

Strengthen Teeth
Fluoride is a natural mineral and essential part of tooth structure. Xylitol helps make ca2+ ions available for absorption by teeth. Both calcium and fluoride strengthen teeth.

Remineralise Teeth
Both fluoride and xylitol help teeth gain minerals available in food by controlling acid production by the cavity causing bacteria resulting into healthy teeth.

Stop Demineralisation
Both fluoride and xylitol help stop demineralisation by stopping acid production, increasing salivary ph and neutralising acid present. As a result, ca2+ and p4- ions stop moving out of the teeth.

Repair Enamel
Both fluoride and xylitol help repair tooth enamel. When demineralisation is minimised and remineralisation exceeds it repairs and strengthens enamel.

Prevent/ Reverse cavity
Both xylitol and fluoride help prevent cavity. When remineralisation is much more than demineralisation it helps in prevention of dental caries.

Xylitol toothpaste with fluoride

A 2015 literature review Trusted Source of 10 studies compared fluoride toothpaste to fluoride toothpaste with 10 percent xylitol added. When children used the xylitol-fluoride toothpaste over a period of 2.5 to 3 years, it reduced their cavities by an additional 13 percent.

Xylitol is a natural ingredient that is believed to:

  • Associate with calcium in aqueous solution
  • Inhibit the dissolution of calcium and/or phosphate ions from enamel
  • Act as a carrier of the calcium required for enamel remineralisation
  • Fluoride inhibits the acid production and growth of oral bacteria.
  • Some studies have shown that: The addition of xylitol to existing fluoride regimes may be beneficial in the prevention of caries
  • Xylitol, used in combination with fluoride, delivered in the form of mouth rinse, has an inhibitory effect on cavity causing bacteria.
  • The combined inhibitory effect of fluoride and xylitol on acid production by bacteria (mutans streptococci) is more than done by any one of them alone.

FAQs of Xylitol & Fluoride

Fluoride and xylitol work synergistically to prevent cavities. Fluoride strengthens tooth enamel and helps repair early stages of tooth decay, while xylitol inhibits the growth of cavity-causing bacteria and reduces acid production in the mouth.
Yes, fluoride and xylitol are often combined in toothpaste, mouthwash, and other oral hygiene products to maximize their cavity-preventing effects.
Fluoride helps prevent cavities by remineralising tooth enamel, making it more resistant to acid erosion from bacteria in the mouth. It also inhibits the growth of bacteria and reduces their ability to produce acids that damage teeth.
When used as directed, fluoride and xylitol are generally safe and well-tolerated. However, some individuals may be sensitive to fluoride or xylitol and may experience mild side effects such as irritation or allergic reactions. It’s essential to follow product instructions and consult a dentist if you have concerns.
Yes, fluoride and xylitol products are safe for children and can be beneficial in preventing cavities. However, parents should supervise children’s use of these products and ensure they are used appropriately based on age and dental health needs.
This may include brushing with fluoride toothpaste containing xylitol, using fluoride mouthwash with xylitol, or chewing xylitol gum after meals to stimulate saliva production and reduce acidity in the mouth.
Yes, fluoride and xylitol can still be beneficial for oral health even in individuals with existing dental work. They help inhibit the growth of cavity-causing bacteria and contribute to overall oral hygiene.
Many toothpaste brands offer fluoride toothpaste with added xylitol like Carinil Xylitol + toothpaste.
Yes, fluoride and xylitol can still be beneficial for cavity prevention in individuals with dry mouth conditions. Xylitol can stimulate saliva production, which helps wash away food particles and bacteria, while fluoride strengthens tooth enamel and protects against acid erosion. Top of Form
