Xylitol Dental Benefits


Dental benefits on oral health has been recognized by The American Academy of Pediatric Dentists (AAPD) to include a significant reduction in tooth decay, as well as contributing to the reversal of cavity formation.

The Benefits of Xylitol on Oral Health

Xylitol Dental Benefits on oral health The benefits of xylitol on oral health are due to the inability to break down this natural sweetener derived from plants, into simple sugars that feed bacteria. It is a 5-carbon sugar alcohol substance found in certain plants, fruits, vegetables, and other natural sources. Research shows that xylitol has many health benefits, including dramatically reducing tooth decay, however, the amount of this substance contained in many foods is inadequate to produce a positive impact on dental health. Therefore, using products containing 100% xylitol or using it as a sugar substitute is recommended to attain its oral health benefits. Eating healthy prevents tooth decay.

How Xylitol Keeps Teeth Healthy

Dental cavities occur when natural bacteria present in the mouth feed on the sugars we eat which remain on the teeth. These bacteria multiply and produce acids that attack the teeth and form cavities, or decay. The bacteria are unable to feed on xylitol and are essentially starved and cannot grow. Studies show that dental benefits include effectively decrease acid-producing bacteria by up to 90%. It also keeps the bacteria from adhering to teeth which decreases plaque.

Because xylitol does not break down as sugar does, the pH level in the saliva is raised and acid does not form. In addition, it can stimulate saliva production which is beneficial in repairing damaged enamel and remineralizing teeth. Saliva containing xylitol has a higher concentration of ammonia and amino acids which raise pH levels resulting in the hardening of tooth enamel.

Xylitol use has been found to significantly reduce tooth decay in both high and low risk groups concerning cavity occurrence.

Xylitol-Containing Products

The most commonly used products containing xylitol are sugar-free chewing gum and candies (such as mints, caramels, and chocolates) which have both been endorsed by six national dental associations.

Other products available are:

  • Toothpaste
  • Dental floss
  • Mouth spray or wash
  • Nasal spray

It is available as a natural bulk sweetener, as well. When purchasing xylitol, look for products containing 100% without high levels of acid, which negates its dental benefits. If the main sweetener is listed as HSH, the content is typically low and ineffectual.

How to Use Xylitol

At one time, the recommendation was to consume 6-10 grams per day. Now, most health care professionals agree that frequency of xylitol use is more beneficial than the quantity consumed. Patients who adhere to a “Strive for Five” regimen will intake more than enough to effectively prevent dental cavities, and frequent exposure will stimulate saliva and replace the sugars and carbohydrates in the mouth throughout the day. Keeping it in contact with the teeth as frequently as possible will help obtain the optimum dental benefits it can provide.

A suggested method for achieving 5 exposures of xylitol per day is:
  • Xylitol toothpaste or mouthwash use in the morning
  • Xylitol gum or candy after breakfast
  • Xylitol gum or candy after lunch
  • Xylitol gum or candy after dinner
  • Xylitol dental floss, toothpaste, or mouthwash before bed

Candy or gum should be chewed or sucked on for at least 2-3 minutes in order to be effective. If you eat snacks throughout the day, adding a xylitol mint or chewing xylitol gum after consumption will give additional dental benefits. Consuming xylitol only occasionally has not shown to provide significant oral health benefits.
