Persistent bad breath can be frustrating and affect confidence in both personal and professional settings. While it's often linked to oral hygiene, deeper factors like digestion and overall health can also play a role. For those seeking more permanent solutions, natural halitosis treatment options are becoming an increasingly popular way to address the root cause and promote long-lasting freshness.
In this article, we'll explore effective, natural strategies to help you feel more confident and maintain better oral health.
What Causes Halitosis?
The most common causes of halitosis are: poor dental hygiene, poor digestion, and the accumulation of toxins in the body.
Other causes are heavy metal toxicity, respiratory infections, salivary disorders, liver disease, kidney disease, indigestion, constipation, smoking, dieting, fever and stress.
Are There Natural Halitosis (Bad Breath) Treatment Options?
Detoxification
Natural treatment for halitosis involves supporting digestion to prevent toxins from accumulating in the gastrointestinal tract. It also involves cleansing toxins from the liver and kidneys so that the body does not have to use the breath to carry toxins out of the body. In particular, toxins in the colon and small intestine can be reabsorbed and cause an odour in the mouth. Consider doing a good colon cleanse (or tell someone you know!). Also consider doing a liver cleanse with herbs like milk thistle and dandelion. Chlorophyll is an important detoxifier, as it will help clean toxins from a variety of organs and tissues in the body. See the section on detoxification for more information on cleansing.
Oral Hygiene
To help reduce bad breath, brush your teeth and tongue after every meal. Replace your toothbrush monthly. Every day, use a tongue scraper to remove dead cells and food debris from the tongue, rinse the mouth with chlorophyll and floss the teeth. Do not use commercial mouthwash because the mouth becomes colonized with bacteria that are resistant to the antibacterial activity of the mouthwash. Mouthwashes can also irritate the tissue in the mouth.
Support Digestion
If you are experiencing bad breath, it could be the result of poor digestion. Food that is only partially digested starts to ferment in the gut and releases unpleasant odours. Enzymes and probiotics can be taken to naturally improve bad breath that is caused by poor digestion. There are complete enzyme formulas that are safe and especially effective when taken with a probiotic/acidophilus supplement. Probiotics can be used in the mouth as well, with the use of a chewable probiotic lozenge. They are convenient and especially effective when taken with every meal.
Diet & Supplements For Natural Halitosis Treatment
Use chewing gum, mints, toothpaste and mouthwash that contain xylitol. Xylitol is a sugar that promotes the growth of bacteria that cause less tooth decay than the bacteria that are commonly found in the mouth. Rinse the mouth with diluted essential oils of anise, cloves, myrrh, parsley, peppermint or rosemary to reduce halitosis.
Dietary considerations for halitosis include drinking lots of filtered water and eating a diet high in raw foods, fibre and plant protein. Eat raw crunchy foods, like apples and carrots, to clean the teeth as you chew. Fibre promotes bowel regularity for toxin removal.
By reducing the consumption of animal proteins, one can reduce the amount of digestion by-products that are used by microbes to produce odour. Avoid spicy foods, tuna, salami, pepperoni, pastrami, anchovies, garlic, onions, blue cheese, beer, coffee, whisky and wine. These foods release odours for hours after consuming them. Also, avoid sticky and stringy foods that can get stuck between the teeth.




I appreciate NN's advice on the causes and recommended natural treatments for halitosis. While poor dental hygiene might be the obvious first choice as to a cause, poor digestion is often overlooked. Good probiotics have helped my children with this issue as well as flossing regularly and eating a healthy, whole foods plant based diet.
Hello Stephanie,
Thank you for sharing. Gut health has a large effect on many health concerns and plays a big role in overall health, but it is often overlooked. We're glad this article was able to bring new information to you.
Stay healthy & well.
Bad breath (Halitosis) is a disease from the stomach and not something you can fight from the mouth only. I use to think I can use all kind of mouth wash product to cure mine and for many years no positive change.
Hello Sean,
We are glad you're enjoying our articles and learning more about your health naturally. Indeed, using supplements that detoxify the body such as chlorophyll and herbs can support this health concern.

Have a healthy day!
I had one scammy dentist really destroy my dental health and had to go through a long, slow journey of restoring it-your advice is great and aligns with much of what I have learned from my own research. Indeed, conventional mouthwash is unhealthy for the mouth microbiome (I personally prefer natural xylitol toothpaste tablets for promoting oral microbiome health...traditional mothwash actually was originally used as floor cleaner-yikes!). I never heard of rinsing the mouth with chlorophyll before and I now wonder if that is one of the reasons why dark leafy greens and other vegetables promote tooth health. Thank you for teaching me something new in an area I care about, NN! :)
Hello Rachel,
We're sorry to hear that, thank you for sharing. We're happy you enjoyed this article and the natural solutions we outlined. Xylitol is great for dental health; however, it's toxic to dogs so be sure to keep it away from your pooch. Chlorophyll is also a great natural deodorizer and detoxifier.
