Your morning coffee and last night’s garlic bread are reason enough for a quick gargle with mouthwash. Every one of us has stressed about bad breath at some point, especially while talking to someone close up, going in for a kiss or getting a whiff or your own breath.

Bad breath can stem from a number of sources, including poor dental health and what you eat and drink. Getting to the root of the issue is important, but there are times when you need a quick breath refresh, and mouthwash is a convenient way to freshen up your breath.

Conventional mouthwash may contain ingredients that can actually make your breath worse in the long run. Here are some ingredients in traditional mouthwash to avoid:

  • Alcohol: can dry out your mouth and disrupt natural saliva production. Saliva is extremely important for good oral hygiene (1). Saliva contains water, electrolytes and proteins, and it remineralizes enamel with calcium and phosphates.
  • Chlorhexidine: an antibacterial agent that can increase your blood pressure, stain your teeth and disrupt the oral microbiome (2).
  • Sodium Lauryl Sulfate: an irritant to the skin in your mouth. Can cause perioral dermatitis (which is a stubborn rash on the outside of the mouth. My daughter is prone to this stubborn rash).
  • Methyl Salicylate: too much can cause low blood pressure, difficulty breathing, convulsions, and vomiting (one tablespoon is equivalent to 23 300 mg aspirin pills).
  • Cetylpyridinium chloride: a quaternary ammonium compound (3)
  • Polyethylene glycol: is used to make personal care products thicker and better able to transport moisture to the skin. The manufacturing process introduces impurities and by-products, such as ethylene oxides and 1,4-dioxane, which are known carcinogenic materials (4).
  • Poloxamer 407 has been linked to elevated cholesterol levels (5).
  • Triclosan classified as a pesticide by the FDA. The overuse of products containing Triclosan has been blamed for bacterial resistance to antibiotics. Triclosan is a known endocrine disruptor and a suspected carcinogen (6).
  • Artificial color + dyes often made from coal tar, and coal tar is recognized as a human carcinogen and may be contaminated with low levels of heavy metals (7).

What Is The Oral Microbiome?

Our mouths are teeming with microorganisms that make up a community we call the oral microbiome. The oral cavity hosts the second largest microbiome in our body, second to the gut. Not only is a balanced oral microbiome important for your overall dental health, it also has an impact on the health of your gut (8).

Can Essential Oils In Natural Mouthwash Disrupt My Oral Microbiome?

Most brands of natural mouthwash contain essential oils to kill bacteria and freshen breath. Essential oils can be strong enough to replace antibiotics depending on the essential oils used and their concentration (9). While essential oils may work to kill off some of the oral bacteria that causes bad breath, strong essential oils may also kill off some of the beneficial bacteria in your mouth, disrupting your oral microbiome. At the time of this writing, there is a dearth of clinical studies on the interactions between essential oils and the oral microbiome.

If you’re having a super bad breath day, go ahead and use a mouthwash with strong essential oils to help combat your bad breath. For everyday use, I’d go for a mouthwash that doesn’t contain really strong concentrations of essential oils. Brands like Bite Mouthwash Bits or Tom’s of Maine Wicked Fresh Mouthwash have mild formulas that work well for everyday use. Lumineux Whitening Mouthwash is another mouthwash that is gentle on the mouth.

Oral Hygiene Best Practices

  • Mouthwash should never replace brushing and flossing. If you’ve ever forgotten your toothbrush when travelling and used mouthwash instead, you already know that it just doesn’t work. You need to brush and floss your teeth, which removes plaque, for fresher breath.
  • Scrape your tongue! It is a MUST for fresh breath and I feel gross if I don’t tongue scrape before leaving the house.
  • A diet high in carbs and sugar and also stress can contribute to an unbalanced oral microbiome, which can lead to bad breath.
  • Get regular dental checkups.
  • There are other medical reasons that can cause bad breath, including tonsil stones, mouth breathing from allergies, infection or certain medications.

Bite Mouthwash Bits

  • Cost: $20 for 124 tablets (4 month supply) or $0.97 per tablet
  • My Take: I’m a huge fan of this eco-friendly brand. Bite Mouthwash Bits come in a glass container. Take 1 bit and crunch it between your teeth to break it up, then sip some water (without swallowing) and swish. Make sure the bits are all crunched up before you gurgle. This left my mouth with a minty fresh feeling without the sting of some mouthwash brands. I also love the added benefit of hydroxyapatite, which remineralizes your tooth enamel. Read more about hydroxyapatite here. All in all, this is really great mouthwash.

Modern day oil pulling is based on an ancient Ayurvedic practice designed to boost oral health, while providing other overall health benefits.
