Toothpaste is something we use every day, yet few people consider the ingredients inside the tube. Some popular toothpaste brands contain chemicals that may pose health risks with regular use. Ingredients such as triclosan, sodium lauryl sulfate (SLS), artificial dyes, and sweeteners can irritate the mouth, disrupt hormones, or cause allergic reactions. Here are several toothpaste brands that have raised concerns among health experts.
1. Colgate Total (with Triclosan)
Colgate Total has drawn criticism for including triclosan, an antibacterial chemical once used to reduce plaque and gingivitis. Although Colgate removed triclosan from its U.S. formula, older versions or international products may still contain it. Triclosan has been linked to hormone disruption, thyroid issues, and the development of antibiotic-resistant bacteria. While Colgate has taken steps to improve its formula, the brand’s long-term use of this controversial ingredient has caused lasting concern.
2. Crest Pro-Health
Crest Pro-Health is marketed as a multi-benefit toothpaste, but it comes with several drawbacks. It contains stannous fluoride, which can lead to brown stains on some users’ teeth. Many Crest products also use sodium lauryl sulfate (SLS), a foaming agent known to cause mouth irritation and canker sores in sensitive individuals. In addition, artificial dyes like Blue 1 and Yellow 5 are often present, which have been associated with hyperactivity in children and allergic reactions.
3. Aquafresh Extreme Clean
Aquafresh toothpastes, particularly the Extreme Clean line, often include SLS, artificial flavors, and synthetic dyes. These ingredients may contribute to oral sensitivity, dryness, and gum irritation. Saccharin, an artificial sweetener also found in some Aquafresh products, is another controversial additive with a debated safety record. While Aquafresh may be appealing for its taste and foaming action, its ingredients list raises concerns for long-term use.
4. Close-Up
Close-Up is promoted more as a breath-freshening gel than a protective toothpaste. It typically contains artificial colors, sweeteners like sorbitol, and SLS, all of which can irritate the mouth or digestive system if swallowed in small amounts regularly. Close-Up lacks strong enamel protection and does not consistently offer the fluoride levels needed for cavity prevention, making it less effective than many other options on the market.
5. Arm & Hammer Whitening Toothpaste
Arm & Hammer’s whitening toothpastes use baking soda, which can be helpful in small amounts. However, these formulas are often very abrasive, potentially wearing down enamel over time. Many versions also contain peroxide and harsh detergents that can cause gum irritation and increase tooth sensitivity. While marketed as a natural alternative, its aggressive whitening approach may not be ideal for daily use.
What to Look for Instead
When choosing a toothpaste, look for formulas free from SLS, triclosan, and artificial additives. Brands that use natural ingredients and are transparent about their sourcing and safety standards are better choices. Toothpastes that contain fluoride in appropriate amounts, or safe alternatives for those avoiding it, can help maintain good oral hygiene without added risks.
Conclusion
Not all toothpaste brands support long-term health. Some contain harsh chemicals or outdated ingredients that can negatively affect your mouth and body. Choosing a safer, simpler formula can reduce your exposure to unnecessary chemicals and improve your oral health over time.
