Hidden Dangers of Dental Floss

We all know the importance of flossing for maintaining healthy teeth and gums, but what if your dental floss is doing more harm than good? It turns out that some common dental floss brands may be exposing you to toxic chemicals every time you clean between your teeth. Let’s look deeper into the hidden dangers of traditional dental floss and what you can do to protect your health.

The Toxic Truth About Teflon in Floss

A recent study revealed that women who used Oral B Glide floss had higher levels of per- and polyfluoroalkyl substances (PFAS) in their blood. PFAS are known as “forever chemicals” because they can remain in your body for years, accumulating over time.^[1] Oral B Glide floss is made from Teflon, the same material that coats non-stick cookware, which is likely why PFAS was found in the blood of frequent users.

PFAS are linked to a wide range of health issues, including:

• Increased risk of cancer
• Liver damage
• Hormonal disruptions
• Weakened immune system
• Developmental harm in children

But the problem doesn’t stop at floss. PFAS are found in various household items, such as clothing, carpets, and food packaging. That’s why it’s particularly concerning when these chemicals show up in something you use in your mouth daily.

The Hidden Dangers of Plastic Fibers in Floss

If your floss isn’t made from Teflon, it could still contain another harmful substance: microplastics. Many dental floss brands use synthetic fibers like nylon or polyester, which shed tiny plastic particles as you floss. These microplastics can enter your body and accumulate over time, potentially leading to inflammation, hormone disruption, and other health problems.

When your gums bleed during flossing, your body is more vulnerable to absorbing these toxic substances, increasing your risk of exposure to microplastics and other chemicals.

What to Look for in a Safer Dental Floss

Making the switch to non-toxic dental floss is easier than you think. Several safer, more natural options are available that can help you maintain oral health without the risk of toxic exposure.

Here’s what to look for:

1. Natural Fibers: Choose floss made from natural materials like silk or bamboo, which break down more easily and are free from harmful chemicals.^[2]
2. Non-Toxic Coatings: Many conventional flosses are coated with synthetic wax or even petroleum-based products. Instead, look for options coated with beeswax or other natural waxes.
3. Eco-Friendly Packaging: Opt for floss that comes in recyclable or biodegradable packaging, reducing your overall environmental footprint.

Healthier Brands to Try

If you’re ready to make the switch, consider these non-toxic dental floss brands:

• Cocofloss: A dentist-developed floss that uses coconut oil for a non-toxic glide.^[3]
• Radius Silk Floss: Made from natural silk and coated with beeswax, this floss is biodegradable and effective.^[4]
• Bamboo Floss: A sustainable and non-toxic alternative to plastic-based floss, often coated with natural waxes for a smooth glide.

The Bottom Line

Flossing is essential for maintaining a healthy mouth, but not all floss is created equal. By switching to non-toxic, natural alternatives, you can continue to support your oral hygiene without risking exposure to dangerous chemicals or microplastics. Your health is worth the change.
