Xylitol vs Sorbitol: What’s the Difference?

Xylitol and sorbitol are both sugar alcohols (polyols) commonly used as alternatives to sugar. They can be found in products such as sweets, chewing gum, toothpaste and other sugar-free foods.

Although they belong to the same family, they have some important differences, particularly when it comes to sweetness and their use in oral-care products.

What are xylitol and sorbitol?

Both xylitol and sorbitol have a sweet taste but are chemically different from sugars such as sucrose.

Xylitol has a sweetness very similar to table sugar, while sorbitol is less sweet, at around 60% of the sweetness of sucrose. Both are processed differently from ordinary sugar, and consuming excessive amounts of either can cause digestive discomfort or have a laxative effect.

Xylitol and oral health

One of the main reasons xylitol is particularly interesting is its long history of research in dental and oral health.

Xylitol has been studied for several decades, particularly in products such as chewing gum, sweets and lozenges. Researchers have investigated its relationship with dental plaque, oral bacteria, saliva and dental caries.

A significant amount of this research has focused on Streptococcus mutans, a group of bacteria associated with dental caries.

Sorbitol has also been widely studied and is commonly used in sugar-free chewing gum and confectionery. Because sorbitol is less readily fermented by many oral bacteria than sucrose, it is generally considered a suitable sugar alternative for sugar-free products.

Xylitol, however, has been specifically investigated for its interaction with oral bacteria and the oral environment, rather than simply being used as a replacement for sugar.

Is xylitol better than sorbitol for your teeth?

There isn’t enough evidence to say that xylitol is universally “better” than sorbitol for dental health. Results can vary depending on the amount consumed, frequency of use, the type of product and what each sweetener is being compared with.

What is clear is that xylitol has a particularly substantial history of research in dentistry. Clinical studies and systematic reviews have examined xylitol-containing chewing gum, sweets and other products in relation to oral bacteria and dental caries.

So, rather than claiming that xylitol is simply superior to sorbitol, it is more accurate to say that xylitol has been more extensively studied specifically in the context of oral health.

Why does Minttu use xylitol?

At Minttu, we chose xylitol because it fits particularly well with the type of product we wanted to create.

Its sweetness is close to that of sugar, it has a characteristic cooling sensation in the mouth, and it has a long history of research in the context of oral health.

This doesn’t mean that xylitol replaces brushing, cleaning between your teeth or regular dental check-ups. These remain the foundation of good oral hygiene.

Instead, we see xylitol as an interesting sugar alternative that can be incorporated into an everyday oral-care routine.

In short, xylitol and sorbitol are both widely used polyols with different characteristics. For a sugar-free sweet designed to be enjoyed as part of a daily oral-health routine, xylitol’s long history of dental research makes it a particularly interesting choice.
