A Closer Look at Xylitol

Xylitol is a naturally occurring sugar alcohol that is found in small amounts in fruits and vegetables. While it tastes sweet like sugar, it contains 40% fewer calories and has a low glycemic index, meaning it does not spike blood sugar levels.

Xylitol has been used for decades in food products like chewing gum and mints as an alternative sweetener to sugar. More recently, it has also become popular in oral care products due to its beneficial effects on dental health.

When consumed, xylitol is not fermented by the oral bacteria that cause tooth decay and erosion. This is because only we humans have the necessary enzymes to break down xylitol completely. The bacteria in our mouths cannot use xylitol to grow and produce acids that erode tooth enamel.

In fact, xylitol has been shown in numerous clinical studies to:

  • Reduce levels of cavity-causing streptococcus mutans bacteria in saliva and plaque by up to 90%
  • Raise the pH in the mouth and return it to a healthy, non-acidic level
  • Stimulate saliva production, which washes away plaque acids and provides minerals to remineralize tooth enamel
  • Prevent bacteria from sticking to teeth and forming damaging plaque biofilms
  • Enhance remineralization and tooth strength when combined with fluoride
  • Reduce inflammation and bleeding of the gums

Consuming or using xylitol regularly can help prevent tooth decay and strengthen weakened tooth enamel to stop cavities from forming. This makes it a valuable addition to dental hygiene regimens.

Now let’s look specifically at whether it is safe and beneficial to use xylitol products after brushing your teeth.

Why Xylitol and Fluoride Work Well Together

Why Xylitol and Fluoride Work Well Together

Fluoride toothpaste is recommended by dentists for its ability to strengthen tooth enamel and make it more resistant to acid attacks. The fluoride ions integrate into enamel, forming fluorapatite which is less soluble and porous than regular hydroxyapatite.

Xylitol complements and boosts the effects of fluoride in a few key ways:

  • Makes enamel more receptive to fluoride: Xylitol increases saliva production in the mouth. The minerals in saliva help break down plaque and prime the enamel surface to readily take up and integrate fluoride ions.
  • Boosts remineralization: Along with fluoride, xylitol enhances mineralization of enamel to counteract early decay. Saliva carries extra calcium and phosphate to redeposit in weakened areas.
  • Prolongs fluoride exposure: Consuming xylitol products after brushing keeps fluoride active on the teeth longer by preventing rinse-off. This extends the time fluoride has to work.
  • Increases uptake: Studies show when used together, significantly more fluoride is deposited into enamel from toothpaste when xylitol gum is chewed afterward, enhancing the protective effects.
  • Works against decay: Xylitol stops bacteria from producing acids that erode fluoride in enamel. The fluoride remains intact and cavity-fighting.

So not only is it safe to use xylitol after brushing, it can actually amplify and prolong the decay-fighting benefits of fluoride toothpaste.

Oral Health Benefits of Using Xylitol After Brushing

Though brushing with fluoride toothpaste is extremely protective, the effects begin to taper off quickly as saliva washes some away and new plaque accumulation begins. Consuming or using xylitol products after brushing teeth can extend the oral health benefits in the following ways:

1. Continued bacteria inhibition

Xylitol prevents disease-causing oral bacteria like S. mutans from adhering to clean teeth. This disrupts the bacterial colony and slows regrowth. Used after brushing, xylitol extends the bacteria-fighting effects.

2. Enhanced remineralization

The minerals in saliva enhance the redeposition effects of fluoride into enamel. This strengthens teeth and reverses early decay more effectively.

3. Further plaque reduction

Plaque begins forming again soon after brushing as bacteria cling to teeth. Xylitol interferes with adhesion and reduces plaque buildup between brushing sessions.

4. Acid neutralization

After eating or drinking acidic items, xylitol helps counteract the acids and return the mouth to a neutral pH not conducive to demineralization.

5. Enamel protection

By stimulating protective saliva flow and preventing bacterial overgrowth and acid production, xylitol shields tooth enamel from dietary and bacterial acids that erode enamel.

6. Cavity prevention

With regular use over time, xylitol can reduce cavity risk by up to 80% by starving harmful S. mutans bacteria of their food source – sugars.

7. Gum and periodontal benefits

Xylitol prevents bacteria that cause gum inflammation and periodontal pathologies. This reduces bleeding and irritation of the gums.

Consuming xylitol throughout the day is beneficial, but using it after brushing amplifies the positive impacts on your oral health.

Potential Drawbacks to Consider

Potential Drawbacks to Consider

While xylitol offers advantages for dental health after brushing teeth, there are a few potential drawbacks to keep in mind:

May affect blood sugar

All sugar alcohols can raise blood glucose and insulin levels. This is of concern for diabetics or prediabetics when consumed in excess.

GI side effects

When consumed in large amounts, xylitol can cause diarrhea, gas, and bloating. Work up to higher doses slowly.

Allergic reactions

Though not common, xylitol can cause hives, stuffy nose, or mouth ulcers in those with sensitivities. Discontinue use if any irritation occurs.

Bacteria can still adhere

If not used immediately, bacteria may still adhere to clean teeth and allow acid production. Use xylitol ASAP after brushing.

No cavity cure

While beneficial, xylitol only reduces cavity risk. Excellent oral hygiene and fluoride use is still vitally important.

Higher cost

Xylitol costs more than regular sugar. Seek out deals online or in natural grocers to reduce the price.

With moderation and smart use, xylitol is a safe, effective addition to oral care regimens for most people. But those with health conditions or cost concerns may want to exercise more caution.
