Questions about Xylitol and how it promotes dental health
How is xylitol good for teeth?
Tooth decay starts with harmful bacteria in the mouth. Sugary foods give these bacteria energy to multiply and produce acids that dissolve the enamel of the tooth and cause decay. Xylitol has the opposite effect, inhibiting their growth, killing the bacteria (they can fall by as much as 90%) and preventing acid attacks.
It also reduces the bacteria’s ability to stick to your teeth so plaque is easier to remove. You can find out more about xylitol here.
How do I make sure I get all the benefits of xylitol?
Dentists recommend you should have at least 5g of xylitol a day. Importantly, this should be split into a few servings, ideally after each meal or snack (when there’s risk of acid attack). You should also try and keep the mint or gum in your mouth for at least a minute so the xylitol has enough time in contact with your teeth.
How much xylitol is in your mints and gum?
Each mint contains 0.55g of xylitol (13.8g per pack) and each piece of gum contains just over 1g (11g per pack) so you’d need to have about 9 mints or 5 pieces of gum per day to get the maximum benefit.
Isn’t all chewing gum good for your teeth?
Yes and no. Sugar free gum helps promote saliva, which in turn helps neutralise the mouth’s pH. This is important because every time you eat and drink, the bacteria in your mouth feeds on sugars and produces acids, leading to decay.
The difference between our 100% xylitol gum and regular sugar-free gum is that xylitol actively reduces the bacteria that cause these acids in the first place, and so prevents problems before they start.
Some sugar-free gum does contain xylitol but usually in very small amounts and the important thing with xylitol is that you need to have 5g a day to get the dental benefits. To put that in perspective, you’d only need 5 pieces of our gum per day, but you’d need multiple packs of regular sugar-free gum as it contains lower levels of xylitol.
How can mints be good for your teeth?
We know it’s quite hard to get your head around the idea that mints can be good for teeth when most are still made with sugar (which feeds the bacteria that cause acids and plaque). But mints made with 100% xylitol (like ours) have the opposite effect and actually reduce this harmful bacteria, preventing acids and plaque. It’s important that you suck our mints and try to keep them in your mouth for at least a minute to make sure the xylitol has enough time in contact with your teeth.
You make some pretty strong dental health claims. How do I know you’re not just making this stuff up?
The benefits of xylitol have been scientifically proven for nearly half a century. It has been the subject of over 600 clinical studies which overwhelmingly demonstrate its ability to reduce plaque.
We’ve also sent all our products to be assessed by the British Dental Health Foundation. Not only did they give them their seal of approval but they also accredited the claim that “Eating Peppersmith with xylitol helps reduce plaque and the risk of tooth decay”.
We work closely with lots of dental health professionals and you can read about them here.
Does eating xylitol mean I don’t have to bother brushing my teeth?
Absolutely not. Our mints & gum are very useful tools to help keep your teeth healthy but you definitely still need to brush at least twice daily, use a good mouthwash and regularly visit your dentist. You can find out more about how to look after your teeth here.
How do I know xylitol is safe?
Xylitol is a completely safe ingredient for humans. JEFCA (The Joint Expert Committee on Food Additives) has put it in the safest possible category a food ingredient can be in.
What about laxative effects? How much xylitol is it ok to eat in one day?
Xylitol is a polyol (a family of sugar alternatives) and as with all polyols, “excessive consumption” can cause a laxative effect. The good news though is that 25% to 50% of xylitol is absorbed in the intestine so it’s much better tolerated than some other sugar alternatives. So the big question is, how much is “excessive”? Well it completely depends on the individual as we are all different. Research has shown that the tolerance for xylitol can be up to 70g for adults and 40g for kids. To put this into perspective a whole pack of mints has 13.8g of xylitol so will be well tolerated by the vast majority of people (there are those that have a sensitivity to xylitol but even they can normally build a tolerance over time).
With all foods though moderation is best and you get all the dental benefits from 5g so there’s no need to eat whole packs at a time. The ideal way to eat them is to have a few mints or pieces of gum at regular intervals throughout the day.
If you’re concerned as you have other food sensitivities you can start off with lower daily amounts of xylitol and increase them as your tolerance will increase over time.
If xylitol is so great why isn’t it everywhere?
Good question. Xylitol is massively popular in other countries, particularly in Scandinavia and Japan where they have a more progressive approach to dental care. The UK is a bit behind on a few things and most manufacturers still opt for ingredients like sugar, sorbitol or aspartame because they are much cheaper. For example, over 80% of mints eaten in this country are made of sugar which is crazy as they just create more bacteria in your mouth and damage your teeth.
It’s quite hard for people to get their head around the fact that there is a sugar alternative out there that is actively good for teeth but the good news is more and more people now know about xylitol.
Do your products help with dry mouth conditions?
We hear from lots of dry mouth sufferers who say our products (particularly our lemon mints) help promote saliva and relieve their dry mouth. People who suffer from dry mouth conditions are also more at risk of tooth decay (because they do not produce saliva to neutralise acids) so they can benefit even more from using our products because of the extra protection they provide. You can read lots more about it here.
What ages are your products suitable for?
Our products are suitable for ages 3 and up. While lots of kids eat our mints it’s up to parents what age they think their children should have gum. The good news is that even babies and very young children can benefit from xylitol. You can read about it here.
Is xylitol potentially harmful to dogs?
There are lots of foods that are completely safe for people but can potentially be harmful for dogs including grapes, chocolate, onions, macadamia nuts, garlic, avocados and xylitol. How it affects them depends on the amount they’ve eaten and the breed and weight of the dog but our message is definitely; xylitol is beneficial to people but can potentially be harmful to dogs so please don’t feed them our products or leave them around where they can eat them.
We are all dog lovers in the office and completely understand why this is such an emotive issue. We have written some more info on it here.
Please remember if your dog has eaten some of our stuff and you’re concerned, we recommend taking them to the vet just in case.
Xylitol sounds really artificial, what is it?
Lots of people think xylitol must be artificial because it has an “X” in it but it’s actually a naturally derived sugar alternative (‘Xyl’ is Greek for wood – think ‘xylophone’) and can be found in lots of living things. We source ours from beech trees and vegetables. You can read more about xylitol here.
Is your xylitol GMO free / where does it come from?
There are concerns around the provenance of xylitol, particularly xylitol sourced from genetically modified Chinese corn cobs. We always aim to use the highest quality and most sustainably sourced ingredients and can confirm that all our xylitol is sourced from European suppliers with very strict manufacturing standards, sustainability policies and GMO free guarantees.
I am a Dental Health professional / I am really interested in the science. How do I find out more?
We have a whole section for dentists, hygienists, pharmacists and other health professionals here.
I’m a dentist/hygienist, where can I get hold of some samples?
Yes. Visit our section for dental health professionals for all the details.
Questions on our other Ingredients and manufacturing processes
Aren’t sugar free things normally full of artificial ingredients?
Are your products suitable for vegans and vegetarians?
Yes, everything we make is approved by the Vegetarian Society as vegetarian and vegan.
Are your products suitable for diabetics, coeliacs and nut allergy sufferers?
Yes. They are all sugar free and low GI (so much better for diabetics than sugary sweets). They are also gluten-free, soya free and nut free. We cannot guarantee though that there may not be tiny traces of gluten and soya in the factory.
Can I swallow your gum?
While our gum base is completely inert and will naturally find its way through your digestive tract and out the other side, we would always recommend you find a bin to put your gum in once you’ve finished chewing. The seven years to digest thing is a myth however in very rare cases it can cause an obstruction so we wouldn’t advise you swallow it.
Where are your products made?
Our products are all made in Finland, which is undisputedly the home of xylitol. We still use the same factory we used when we founded Peppersmith in 2009 and we can absolutely confirm that Finland is the best place in the world to make and learn about xylitol. You can read about the history of xylitol here.
What is your sustainability policy?
We are a company who really care about how we do business and you can read about our company values here. We promise to always do the best we can to make our products good for you without being bad for the environment. That goes for our ingredients and packaging through to our supply chain.
