What is Xylitol? Ask a General Dentist in Apex NC

, by

We all know about the negative health effects of sugar, especially when it comes to teeth. Fortunately, artificial sweeteners don’t have the same effect on teeth as sugar, and can help you have a much healthier smile. One artificial sweetener, xylitol, even has positive effects on teeth. Here’s everything you need to know about Xylitol from a dentist in Apex, NC.

What is Xylitol?

Xylitol is categorized as a sugar alcohol. That means that it combines traits of sugar molecules and alcohol molecules to create a structure very similar to that of sugar. However, Xylitol has much fewer calories, doesn’t raise blood sugar levels, and actually kills the harms the bacteria that live on your teeth and cause tooth decay.

Is Xylitol Natural?

Despite the pharmaceutical-sounding name, Xylitol is found in many fruits and vegetables, and is even produced in small amounts by the human metabolism. It can also be processed from trees like birch, or from a plant fiber called xylan. For these reasons, most health professionals consider it to be a safe, natural substance.

How Xylitol Helps Your Teeth

Xylitol functions a lot like a “mousetrap” for the bacteria that live on your teeth. Normally, these bacteria ingest sugar and carbohydrates and convert them into acid, which destroys the tooth enamel. After the bacteria ingest xylitol, however, they are no longer able to absorb glucose. With their energy-producing pathway clogged up, they end up starving to death. That’s why many dentists recommend using xylitol-sweetened chewing gum: it’s one of very few things that can actually kill harmful tooth bacteria.

Why Xylitol is Toxic to Dogs

If you buy gum or candy that contains Xylitol, it is very important to keep it away from any dogs in your house. When a dog eats xylitol, its body mistakes it for glucose and starts producing large amounts of insulin. Then, the dog’s cells start absorbing glucose from the bloodstream, which can lead to hypoglycemia, low blood sugar, and even death. Xylitol may also have detrimental effects on liver function in dogs, with high doses causing liver failure.

It only takes 0.1 grams per kg of body weight for a dog to be affected. To put that in perspective, a 6 pound Chihuahua could get sick or die from eating a single piece of xylitol chewing gum.

Dog Owners: Watch Out for These Household Items Containing Xylitol 

, by

We have written before about xylitol, a sugar alcohol that has excellent benefits for dental health. Although xylitol is highly recommended for fighting tooth decay in humans, however, it poses a significant risk to dogs. When a dog ingests xylitol, its body releases a massive surge of insulin, and this rabid influx can quickly become life-threatening. Therefore, it is important to look out for the following common household products which contain xylitol, and keep them out of your pup’s reach. 

Sugar-Free Gum

Dentists love when our patients chew sugar-free gum containing xylitol. Not only is the ingredient deadly to harmful tooth bacteria, the action of chewing stimulates also saliva production, which further helps cut down on bacteria. However, xylitol-containing gums can cause serious problems for your dog. In fact, the Pet Poison Helpline cites gum as the source of nearly 80% of xylitol poisoning cases. The solution? Keep all of your gum in a closed cabinet or high place. If your dog does get its teeth on some gum, be sure to note the brand and your best guess at the amount ingested. Since different gums contain different amounts of xylitol, this is crucial information for your vet. 

Food Items  

More and more consumers are checking the calories in food items before making their purchases, so in order to keep the calories low, many companies are forgoing natural sugar in favor of xylitol. These items, sometimes marked as “low-sugar” or “sugar-free,” are much more dangerous than other items on this list, because they contain a much higher amount of sweetener. Therefore, pay close attention to the ingredient list on all foodstuffs you buy, and never let a dog snack on human food, no matter how cute their begging face might be. Ketchup, peanut butter, protein bars, and pudding are all common culprits of doggy xylitol poisoning. 

Lotions, Gels, and Deodorants

While xylitol is used in food as an artificial sweetener, it also has great humectant properties, or the ability to help a product retain its moisture. For this reason, many lotions, gels, toothpastes, and liquid or “meltaway” medications contain it. Like everything on this list, your best course of action is to keep such products out of reach of your four-legged friends. Even if you think it’s unlikely your pooch will take a bite out of your deodorant, it’s better to be safe than sorry.

Our Apex Dentist Explains why Xylitol is Good for Teeth, Bad for Dogs

Now that Halloween’s in the rear-view mirror, you might be motivated to give your body a break from all that sugar by switching to low-calorie sweeteners. If so, xylitol is a great option, because it’s natural, tasty, and deadly to the bacteria on your teeth. In fact, xylitol is one of the few things that can truly kill cavity-causing bacteria, which is why dentists highly recommend it. However, it’s important to be aware that xylitol is also very dangerous to dogs, for reasons we will explain below.

What is Xylitol?

Xylitol is found naturally in fruit, vegetable fibers, hardwood trees, corncobs, and certain other plant species. It was first used as a sweetener in Finland during World War II, when sucrose was unavailable. Xylitol has become very popular in the last few decades due to the fact that it’s just as sweet as sucrose, but has far fewer calories. Additionally, xylitol causes very little insulin release in humans, making it an excellent alternative for people with diabetes, prediabetes, obesity, or other metabolic problems. However, this is unfortunately not the case when it comes to dogs and other animals.

Why Does Xylitol Harm Dogs?

In people, rats, horses, and rhesus monkeys, xylitol causes little to no increase in insulin release or blood sugar levels. However, in species like dogs, cats, cows, goats, rabbits, and baboons, xylitol causes a large insulin release and drop in blood sugar. For dogs, the insulin release from is so massive that it causes the blood sugar to drop dangerously low, resulting in weakness, trembling, seizures, collapse, and even death. At very high dosages, xylitol can cause massive liver necrosis in dogs, in which large numbers of liver cells die abruptly, killing the animal.

Xylitol is just as harmful to cats, but there is less cause for concern when it comes to them. This is because cats typically ignore xylitol-heavy foods like gum, cookies, cake, and peanut butter.

Foods Which Contain Xylitol

While we highly encourage patients to chew sugar-free gum that contains xylitol, we also don’t want any harm to come to family pets. Make sure that you check the following products carefully for xylitol:

  • Toothpaste
  • Mouthwash
  • Chewing gum
  • Peanut butter
  • Sugar-free candy
  • Sugar free breath mints
  • Fruit drinks
  • Jellies and jams
  • Cereals
  • Baked goods
  • Sugar-free puddings and Jello
  • Over-the-counter vitamin supplements

Be aware, too, that not all product labels clearly state whether or not they contain xylitol. If a label states only, “artificially sweetened,” presume that it contains xylitol to err on the safe side. Always keep xylitol-containing products high out of reach, and try to induce vomiting immediately if you think your dog has ingested any.
