Xylitol products: Which are the best / most effective in preventing tooth decay?

How to identify products that contain an effective dosing of xylitol.

Finding xylitol products can be difficult. Finding products that actually contain a significant quantity of xylitol, one that can help you achieve the daily dosing level that you need for optimal cavity prevention, can be even harder.

Not all manufacturers make the same quality of product.

The xylitol-sweetened products that you find available here in the U.S. typically seem to fall within one of two categories. One is those products made by specialty companies whose targeted customer is the dentally conscious consumer seeking anti-cavity protection. These companies typically make a range of high quality products such as chewing gum, mints, toothpaste, and mouthwash and clearly mark each product's xylitol content on its packaging.

On the other side of the coin are those companies who have taken notice of the growing demand for xylitol products and have decided to add these types of items to their product line so not to miss a sale. In many instances the actual amount of xylitol formulated into these products is low. This is because xylitol is relatively expensive in comparison to other sweeteners and inferior manufacturers will skimp on it in favor of cheaper alternatives (especially sorbitol and manitol).

Some manufacturers do not document their product's xylitol content.

Surprisingly, not all manufacturers state the xylitol content on the label of their products. Doing so is not a requirement under U.S. law, so they don't. It's easy to understand why a manufacturer of a low-quality product would skip this documentation. They are after a sale based on the fact that their mint, stick of gum or whatever does indeed have some xylitol content. However, they don't want you to be able to make a direct comparison between their product and a competitor's because they anticipate they will lose that sale because their xylitol content is so low.

There is also a class of manufacturers who seem to make high-content xylitol products but for some reason are also guilty of not documenting the specific amount on their packaging. It seems so strange that a company would develop a line of products aimed at satisfying the demands of dentally conscious consumers but not provide this information. These are precisely the consumers that understand that their daily xylitol consumption needs to be gauged, so they can achieve that level that provides optimal anti-cavity protection. Go figure.

How to judge the level of xylitol that a product contains.

There are a few different ways you can identify or estimate the xylitol content of a product.

Look for documentation right on the product's packaging. This is of course the most logical way to determine a product's xylitol content. However, you will find that many products simply do not provide this information. It is our opinion that every xylitol product should have this documentation on it and if it doesn't you shouldn't buy it (for one of two reasons we discuss just above).
You can estimate the relative content of products by comparing where xylitol appears in their list of ingredients.

The compounds found in any product are listed in descending order in its ingredient list. Those ingredients contained in the highest amount are listed first. If one product shows xylitol at the head of its list and another product (containing similar ingredients) lists it further down, then you can assume that the former example contains the greater amount of xylitol.
Look for other sugar-substitutes in the product's ingredient list. Xylitol is a relatively expensive sweetener, especially in comparison to other sugar-alcohols (sorbitol, manitol). If you are comparing two products and one is formulated with just xylitol whereas the other contains additional sweetening compounds, it can be assumed that the former product will have the higher xylitol content.
Be aware of the typical xylitol content of products. Comparing ingredient lists can only provide a relative comparison between two products, not exact amounts. However, once you have found a quality product take note of its ingredient list and documented xylitol content. Then, in those instances where your favorite brand is not available, simply look for one that has a very similar list of ingredients with xylitol listed in a similar position. It is a fairly safe assumption to expect that the unfamiliar brand will have a similar xylitol content as your favorite brand.
