Frequently Asked Questions

Our mints are made from a unique formula of green tea extract, xylitol, calcium phosphate and natural peppermint oil.

No. Dr. Heff’s mints contain no sugar at all. But to keep them tasting great, we use a natural sugar-free sweetener called xylitol, which is found in the fibres of plants and is proven to help prevent tooth decay. What's more, the xylitol we use comes from certified GMO-free maize grown in Europe.

No. Dr. Heff's mints do not contain any caffeine and they are also completely GMO-free.

Scientific research has shown that your teeth get the greatest benefit from xylitol by taking it throughout the day. So you can enjoy taking Dr. Heff's mints after mealtimes, at work and on an evening out. It’s also best if you suck on the mint, rather than chewing it, so that it dissolves gradually in your mouth.

The slightly speckled appearance comes from the green tea extract, one of Dr. Heff's natural, healthy ingredients.

Yes. But don’t take our word for it: in a survey of 200 people, 90% said that Dr. Heff’s mints tasted “as good or better” than their previous favourite mint. “I felt like I’d just brushed my teeth,” was a common reaction. This is exactly the experience we hope you'll have too.

The simple answer is: everyone in the world aged over three.

Yes. Dr. Heff’s mints are beneficial to people of all ages. In fact, in clinical studies, doses of xylitol syrup of 8g per day have been given to 15-month-old babies to reduce tooth decay. However, because xylitol liquid is a more appropriate way for very young children to benefit from its teeth-protecting properties, we only recommend Dr. Heff’s mints for children aged three and upwards.

There are certain common human foods that vets recommend we don’t give to dogs in particular, including chocolate, onions and avocados. In a similar way, xylitol has many health benefits for humans but is toxic to dogs, can be harmful to ther animals.
