Why Your Toothbrush Isn’t as Clean as You Think

The science behind UV-C light and Oralux toothbrush sanitiser

The invisible dirt on your toothbrush and the technology we use to clean it.

Brushing twice a day simply reintroduces bacteria to your mouth.

After a single use, your toothbrush becomes a breeding ground for bacteria, mold, and fungi — especially when left damp in shared bathrooms. Research has shown that toothbrushes can harbor E. coli, Staphylococcus aureus, Streptococcus mutans (linked to cavities), and Candida albicans (which causes oral thrush) Marc-Kevin Zinn, 2020, PubMed: The Toothbrush Microbiome

Studies confirm that contaminated brushes may contribute to:

  • Tooth decay
  • Gum disease
  • Fungal infections
  • Halitosis (bad breath)
  • Respiratory infections (especially in children and the immune compromised)
UV-C Light Scientifically Proven to Be More Effective

A study published in the National Library of Medicine showed that UV-C light toothbrush sanitizers outperformed boiling water and mouthwash in decontaminating toothbrushes.

UV-C Light: Trusted by Hospitals, Now in Your Bathroom

Oralux uses UV-C light in the 253–275 nanometer range, a wavelength scientifically proven to destroy bacteria by disrupting their DNA and halting their ability to multiply.

This same technology is used in:

  • Hospital disinfection systems
  • Food production facilities
  • Water purification systems
  • Laboratory air filtration

According to the National Institutes of Health, UV-C light sterilisation can eliminate over 99.9% of bacteria and viruses, including those commonly found on toothbrushes.
