1. Titanium dioxide: A risky whitening agent
Titanium dioxide is added to toothpaste to give it that clean, white appearance. While this might make the toothpaste look appealing, it’s a potential health hazard.
Why is it harmful?
Titanium dioxide nanoparticles can be absorbed by our body through our gums. Studies suggest these tiny particles may cause cellular damage, inflammation, and even disrupt your immune system. The International Agency for Research on Cancer (IARC) has classified titanium dioxide as a “possible carcinogen” when inhaled, raising concerns about its long-term safety.
2. Sodium Lauryl Sulfate (SLS)
Do you love the foamy lather when brushing your teeth? All credit goes to sodium lauryl sulfate (SLS), a chemical detergent used to create foam. But this ingredient can do more harm than good.
Why is it harmful?
SLS is a known irritant that can cause issues like mouth ulcers, gum irritation, and even worsen existing oral conditions, This information has been mentioned in a study done in 2022. It strips the tissues in our mouth of their natural moisture, making our gums more vulnerable to infections.
Beyond oral issues, SLS can disrupt our body’s hormonal balance. Since it’s easily absorbed into the bloodstream through our mouth, longer exposure may contribute to problems such as skin irritation and organ toxicity. While the foam might feel like it’s cleaning your teeth better, it’s just a cosmetic effect that doesn’t actually improve oral hygiene.
3. Triclosan
Triclosan is an antibacterial agent once marketed as a hero ingredient in toothpaste. However, its harmful effects far outweigh any benefits.
Why is it harmful?
Triclosan can be harmful for your hormones. This happens particularly to the hormones related to our thyroid. It is also linked to antibiotic resistance, meaning it could reduce your body’s ability to fight infections. The FDA has banned triclosan in certain products, but it can be still found in some toothpastes.
