20 Nov 5 Ingredients to Avoid in Toothpaste and Mouthwash
You may be surprised to learn that the toothpaste and mouthwash you use every day contain toxic ingredients. These harsh chemicals and artificial ingredients can be quite harmful when you’re exposing your mouth to them twice a day.
Even if you spit thoroughly, small amounts of the products you use will get absorbed through your gums, swallowed, or inhaled. Scary, right? But it’s not always easy to tell which products are dangerous and which ones are safe.
If you’re ready to detox your oral care routine, here’s what to watch out for and how to find safe alternatives.
Five Dangerous Toothpaste and Mouthwash Ingredients to Avoid
1. Sodium Lauryl Sulfate (SLS)
While it makes your toothpaste lather more easily, this foaming agent can also do a lot more harm than good. SLS irritates your gums and makes canker sores worse. It also dries out your mouth, which increases your risk of bad breath, cavities, and gum disease.
Look for SLS-free toothpaste made with gentle, plant-based ingredients. Even though they might sound a little bit scary, ingredients like cocamidopropyl betaine and decyl glucoside are actually perfectly safe.
2. Artificial Sweeteners (Aspartame, Saccharin, Sucralose)
Although they make toothpaste and mouthwash taste better, artificial sweeteners often come with health concerns. Some disrupt gut bacteria, while others have been linked to headaches and allergic reactions.
Choose products with natural sweeteners (like xylitol, erythritol, or stevia) that support good oral health by reducing cavity-causing bacteria.
3. Triclosan
Triclosan was first introduced as an antibacterial agent, but it has since raised concerns. Its role as an endocrine disruptor and its potential to contribute to antibiotic resistance led the FDA to ban it from certain personal care products.
Look for products with natural antibacterial agents such as tea tree oil, neem, or myrrh extract that won’t harm your body’s microbiome.
4. Ethanol
Alcohol is commonly used in mouthwash to kill germs, but it can also dry out your mouth, irritate your gums, and disrupt beneficial bacteria.
Look for mouthwash with gentler antimicrobial ingredients like aloe vera, witch hazel, peppermint, and clove. You can also make your own Himalayan salt rinse at home.
5. Artificial Dyes and Flavors
The synthetic dyes in toothpaste and mouthwash can trigger allergies and sensitivities in some people. The same goes for artificial flavors.
Look for products that are free from synthetic dyes and flavored naturally with essential oils like peppermint, cinnamon, or spearmint.
How to Choose Safe Toothpaste and Mouthwash
- Read labels carefully. Research any ingredients you’re unfamiliar with.
- Support a healthy microbiome. Avoid antibacterial overkill and use gentle, plant-based ingredients instead.
- Look for the ADA seal of acceptance. Just because a product is “natural” doesn’t mean it’s safe. The ADA seal means the product has been evaluated by experts for safety and effectiveness.
- Ask a holistic dentist! If you’re uncertain about which products are safe, they will be happy to offer advice.
