News & Research:

  • Effect of natural sweetener xylitol in preventing tooth decay still unproven - Science Daily, 3/26/15 - "they found low quality evidence that levels of tooth decay were 13% lower in those who used a fluoride toothpaste containing xylitol for three years, compared to those who used a fluoride-only toothpaste. For other xylitol-containing products, such as xylitol syrup, lozenges and tablets, there was little or no evidence of any benefit"
  • Top 4 Ways to Beat Bad Breath - ABC News, 4/30/14 - "the bacteria species that dominate the tongues of those with healthy mouths are different than the species that inhabit the tongues of those with bad breath. One of the prime bacteria offenders is strain of streptococcus, but recent research has shown that consumption of probiotics reduces streptococci counts significantly ... While eating yogurt is a good way to get probiotics in your diet, you might consider a simple supplement to boost your probiotic counts. Both Flora Udo’s Choice and Garden of Life offer a good basic probiotic supplement ... chewing xylitol gum actually decreases the amount of those same stinky streptococci bacteria" - See probiotic products at Amazon.com and xylitol gum at Amazon.com.
  • Big Xylitol Trial Finds Scant Benefits in Adult Caries - Medscape, 1/16/13 - "In the X-ACT trial, 691 participants aged 21 through 80 years consumed five 1-g xylitol or placebo lozenges a day for 33 months. Researchers counted the decayed and filled surfaces of their teeth, where decay penetrated the enamel (D<2FS), at baseline and at 12, 24, and 33 months ... the crude annualized D<2FS increment in the xylitol group was 2.69 compared with 2.98 in the placebo group, a 10% lower increment. However, this difference did not reach statistical significance ... other research has led him to believe a larger dose (6 - 10 g/day, in 2 - 3 applications) is more efficacious, at least in children ... Xylitol is not a magic bullet, but that doesn't mean it doesn't work at all ... In addition, xylitol chewing gum may have a mechanical effect of scrubbing plaque from teeth or might stimulate saliva flow more that lozenges ... One reason the researchers chose lozenges in their adult population is that chewing gum is less socially acceptable among adults ... A few patients seem to get caries no matter what you do ... You have to throw everything you have at them" - Note:  I've always felt that people were wasting their time with the lozenges because it's not getting the xylitol to where it needs to be in an effective way.  The study should have been done with the gum.  I'll bet that 85% of the xylitol from lozenges goes down your throat without even touching most of the teeth.  If you're going to pay the bucks for the study, do it right.
  • My dentist recommended xylitol gum to prevent cavities.  Basically the bacteria eat it thinking it's sugar but end up starving from lack of calories.  The same theory supports using it to prevent halitosis.  Here's some research on:
