What Is Xylitol?

Xylitol (zai-luh-taal) is a natural compound found in some plants, including fruits and vegetables such as carrots, strawberries, and yellow plums.

It’s a type of polyol or sugar alcohol—a carbohydrate that resembles the chemical structure of sugar and alcohol but doesn’t actually contain them.

Xylitol is often added to dental care products like toothpaste because it adds sweetness. Plus, it’s good for your teeth and oral health.

Benefits of Xylitol Toothpaste

Xylitol toothpaste is an alternative to toothpastes containing sugars and artificial sweeteners. Here are the benefits of xylitol in toothpaste:

1. Stops Oral Bacteria from Thriving

The problem with sugar is that it feeds harmful bacteria, causing them to thrive in your mouth. Bad bacteria can’t use xylitol for energy.

Studies show xylitol inhibits cavity-causing bacteria such as:

• Streptococcus mutans (S. mutans)
• Streptococcus sobrinus (S. sobrinus)
• Helicobacter pylori (H. pylori)

This prevents them from thriving and producing acids that can damage your tooth enamel. It lowers your risk for tooth decay, plaque formation, and gingivitis (a disease that causes inflammation of the gums).

2. Encourages Saliva Production

Xylitol increases the saliva in your mouth, which washes away food particles, bacteria, and other harmful microorganisms—like fungi.

Saliva also creates a protective layer called a pellicle over your teeth and the soft tissues of your mouth so bacteria don’t stick to them.

The increased saliva production reduces microbial growth and helps you avoid oral diseases. It relieves symptoms of dry mouth (xerostomia) and prevents bad breath (halitosis) which typically accompanies it.

3. Remineralizes and Strengthens Teeth

Xylitol helps neutralize the acids in your mouth through saliva production. This prevents enamel erosion, demineralization, and teeth stains.

Since saliva contains calcium, fluoride, and phosphate, it can also remineralize your tooth enamel and the dentin underneath it.

Remineralization strengthens teeth and reduces its sensitivity to cold and heat. It also makes you less prone to developing dental cavities.

4. Maintains Oral Health

The increased saliva flow from xylitol reduces the ‘bad bacteria’ in your mouth and supplies ‘good bacteria’ with the nutrients they need.

Regular consumption of xylitol products has been shown to maintain this balance. A healthy oral microbiome inhibits the growth of harmful bacteria and lowers your risk for dental caries and gum disease.

5. Naturally Sweetens Toothpaste

Commercially-produced xylitol (like the one found in xylitol toothpaste) is derived from plant-based sources such as birch bark and corn cobs.

This makes xylitol toothpaste a natural alternative to toothpastes with artificial sweeteners such as aspartame, stevia, sorbitol, and sucrose.

Xylitol is just as sweet as table sugar but has 40% fewer calories. It also has a low glycemic index which means it won’t cause your blood sugar to spike.

Safety and Possible Side Effects of Xylitol

According to the U.S. Food and Drug Administration, xylitol can be ‘safely used in foods for special dietary uses’. However, you should only consume more than what’s needed to get the desired effect.

For cavity prevention, 7 to 20 grams of xylitol per day divided across three to five doses is enough. Too much xylitol may cause these side effects:

• Mouth sores
• Diarrhea
• Constipation
• Bloating
• Gas
• Cramps

Remember to talk to your dentist before purchasing xylitol toothpaste.
