Avoiding Toxins in Oral Health Products: A Guide for Better Choices

Our bodies are exposed to a variety of chemicals daily, many of which are found in personal care products, including those used for oral health. This is especially concerning as the mouth and gums readily absorb substances, which can quickly enter the bloodstream. Additionally, certain ingredients in oral health products can disrupt the natural balance of bacteria in the mouth, which is vital for maintaining good oral health. Below is a guide to help you identify harmful ingredients to avoid and make informed choices for your oral care routine.

Ingredients to Avoid in Oral Health Products

1. Triclosan

      •     Found in some antibacterial and antifungal products.

      •     Known as an endocrine (hormone) disruptor and may contribute to antibiotic resistance.

      •     Although banned from soaps and hand sanitisers in 2017, it can still be found in some consumer goods like cutting boards and vacuum filters.

2. Sodium Lauryl (Laureth) Sulphate (SLS/SLES)

      •     A foaming agent used in toothpaste.

      •     Can cause mouth irritation, canker sores, and cracked corners of the mouth.

      •     Linked to inflammation and hypersensitivity to certain metals.

3. Artificial Sweeteners

      •     Common in toothpastes for flavour, such as saccharin and aspartame.

      •     May disrupt beneficial gut bacteria, impacting overall health.

4. Propylene Glycol and Polyethylene

      •     Synthetic compounds found in some toothpastes.

      •     Can disrupt hormonal balance, irritate oral tissues, and may cross the blood-brain barrier.

5. Titanium Dioxide

      •     Used to whiten toothpaste.

      •     Concerns are particularly high with nanoparticle forms, which are linked to potential carcinogenic and neurotoxic effects.

6. Alcohol-Based Mouthwashes

      •     Dry out oral tissues and disrupt the oral microbiome.

      •     Increased dryness is linked to a higher risk of oral cancer and irritation.

7. Teflon-Coated Dental Floss

      •     Some flosses (e.g., Glide) use polytetrafluoroethylene (PTFE), a chemical linked to cancers and hormone disruption.

8. Fluoride

      •     Fluoride use is controversial as it can accumulate in tissues, displacing iodine and potentially causing harm.

      •     Overuse, especially in children, can lead to dental fluorosis (mottled teeth).

      •     If used, ensure it is applied topically and rinsed out, not ingested.

What Products Should You Use?

Toothpastes or Tooth Powders

      •     Choose gentle, non-abrasive options to protect enamel.

      •     Tooth powders made from baking soda or natural chalk (calcium carbonate) are safe if brushing is done gently.

      •     Products with amorphous calcium phosphate can help remineralise teeth and prevent decay.

      •     Avoid overly abrasive options or those with artificial additives.

Mouthwashes

      •     Opt for natural mouthwashes without alcohol, artificial colours, or flavourings.

      •     Look for products with essential oils, safe sweeteners (e.g., xylitol, stevia), or minerals to support enamel health.

      •     DIY recipes for natural mouthwashes are also available.

Dental Floss

      •     Use waxed floss made from natural materials, avoiding Teflon-coated options.

      •     Thicker flosses, particularly woven or expanding types, are often safer and more effective at cleaning between teeth.

      •     Contact manufacturers for ingredient details if unclear.

Bleaching Products

      •     Professional bleaching by a dentist is the safest option.

      •     Over-the-counter bleaching trays should be used sparingly, ideally for short periods (e.g., 30 minutes or less) to minimise exposure to chemicals like peroxide and nitrates.

How to Choose Safer Products

When selecting oral health products, always check the ingredient list and prioritise products free from harmful chemicals. Opt for those that support the natural balance of your oral microbiome and overall health. By avoiding the toxins listed above, you can protect your oral and systemic health while maintaining a bright, healthy smile.

Remember: Your oral care routine plays a significant role in your overall health. Make informed choices to ensure your products are as safe and effective as possible.
