Many dentists feel the regular use of xylitol is a very effective way to prevent gum disease and tooth decay.

Xylitol is a 5-carbon sugar alcohol used as a sweetener.  It is very different from other sugar alcohols like sorbitol and mannitol.  Its very low glycemic index of 7 makes it the ideal sweetener for diabetics.  Humans don’t actually use insulin to metabolize it!

Xylitol was originally extracted from birch bark, but now mainly comes from corn cobs.  American Indians chewed on sticks made from birch bark, which is likely why their dentition was so good.  Military dentists provide xylitol to troops in the field who often aren’t able to brush regularly.

Xylitol works by killing the bad bacteria.  The disease causing bacteria are able to ingest xylitol, but they are not able to use it for food.  Therefore, they starve themselves to death!  Xylitol promotes the growth of good bacteria, which are not as adherent to teeth, so are more easily brushed and flossed off.

Some other pearls about xylitol:

• The bacteria mix produced by consuming xylitol is less adherent to teeth, so it brushes off more easily.
• Xylitol plus the fluoride rinse whiten teeth.  The film of bacteria can accentuate staining substances like coffee and red wine.  Stains brush away when the less adherent good bacteria are released.  Enamel strengthened with fluoride will better resist staining.  Also, strong enamel reflects light and will appear whiter than soft teeth that are more translucent and show the underlying yellow dentin.
• Studies show that 6-10 g must be consumed daily to receive the beneficial effects.  More is not likely dangerous, just not shown to be more effective.
• Xylitol must be consumed 3-5 times over the course of a day.  Gum, breath mints, and a granular form for drinks make this easy.
• Xylitol effectively neutralizes an acidic meal or drink, so consuming xylitol after meals and snacks is perfect.
• Purchasing 100% xylitol without significant other ingredients is important.  Other ingredients can reduce its effect.
• Keep xylitol away from your dog.  It can be deadly!

Reducing Sinus and Ear Infections

Bacteria found in our nasal passage are similar to those found in the mouth. Studies have found that young children who consume xylitol experience 42% fewer ear infections.  Xylitol nasal spray is available that may reduce sinus infections.

There is very little downside to xylitol consumption.  Some people get some mild gastrointestinal symptoms like gas.  Most find this gas resolves with continued use.
