Imagine waking up to a bright, sunlit morning. You turn to your side, and your partner is fast asleep with a smile on their face. At that exact moment, they awake and bid you good morning. It sounds like the perfect start to the day, right? Well, not quite, especially if in addition to their greeting, you catch a whiff of bad breath. Oof. Talk about a downer. 

Discover what causes bad breath and how it can be prevented.

Reasons for Foul-Smelling Breath 

Chronic bad breath (also called halitosis) often relates to a dry mouth or lack of dental care. It can also indicate an oral disease or illnesses affecting other areas of the body. 

Traditional Chinese Medicine (TCM) believes that the condition stems from pathogenic factors like phlegm, Heat, Dampness and Qi (vital life force) Stagnation in the Stomach, Lungs and the Large Intestines.

Dry mouth 

A decrease in saliva production prevents the mouth from cleaning itself and removing food debris and particles. Dry mouth can happen for a few reasons, including frequent mouth ulcers, a salivary gland disorder, or the use of certain medications.

Poor oral hygiene 

Not brushing or flossing teeth regularly is another common cause of bad breath. Food particles can wedge between teeth when a person eats. Bacteria disintegrates these particles, giving rise to foul breath. It can also make a person vulnerable to tooth decay and gum diseases.

Likewise, a person can also have bad breath if they use dentures but don’t clean them correctly. 

Underlying medical conditions 

Postnasal drip – a feeling of excess mucus dripping down the throat and back of the nose – chronic bronchitis or sinusitis, and nose, windpipe and lung infections can make a person prone to bad breath.

People with diabetes or gastrointestinal, kidney, or liver disorders can also be susceptible to the condition.

How to Help a Partner (or Yourself) Say Goodbye to Bad Breath 

To avoid turning off a partner or being turned off by bad breath, the practice of proper oral care habits is necessary. Examples of these are: 

  • Stopping tobacco use 
  • Flossing once a day 
  • Drinking enough water 
  • Limiting the consumption of alcoholic or caffeinated beverages 
  • Cleaning the tongue with a toothbrush or tongue scraper 
  • Eating foods or chewing sugar-free gum to boost saliva production 
  • Brushing teeth or dentures twice a day for two minutes at a time 
  • Visiting the dentist every six months for a check-up and professional teeth cleaning 

Use proper brushing and flossing techniques 

Are you brushing and flossing your teeth daily like you’re supposed to? If you still have bad breath despite doing so, there’s a possibility that you’re not doing it the right way.  

Proper brushing technique starts with using a soft-bristled toothbrush. The toothbrush must also be a shape and size that helps clean your mouth comfortably. Hold it at a 45˚ angle and use short strokes. Aim to reach the inside, outside, and top of each tooth.

Refrain from pressing hard against your teeth as it will not work as well if the bristles are flattened. It should be replaced after three to four months or if it looks worn. 

Separately, the appropriate way to floss involves firstly knowing the right amount of cord to use. Break off approximately 18 inches of floss. Wrap it around your middle fingers and use your thumbs and forefingers to hold it tightly. Then, guide the middle section of the floss between your teeth, rubbing gently to remove food debris and particles.

Tackle oral or gum disorders 

If you’ve been diagnosed with gum disease, your gum line is likely inflamed. To treat the condition, it’s advisable to undergo a cleaning procedure performed by a periodontist. Doing so will help remove the bacteria, plaque, or tartar build-up causing the inflammation.  

Likewise, the periodontist or a dentist may propose the use of an anti-microbial mouth rinse, especially if the plaque deposits are extensive.

Resolve Lung phlegm and Heat 

The consumption of herbal formulas and ingredients can be helpful for these constitutional imbalances. A few of the formulas that can be considered include: 

  • San ren tang (三仁汤)  
  • Bai he gu jin tang (百合固金汤)  
  • Ma xing shi gan tang (麻杏石甘汤)  
  • Qian jin wei jing tang (千金苇茎汤)

How Safe are These Proposed Treatment Options? 

According to Real Health Medical Senior TCM Physician Brandon Yew, acupressure, and herbs and formulas are only suitable for mild or generic cases of bad breath, which can be complicated with varying underlying pathologies.

He cautions, “Some people may benefit, and others can even experience a worsening of their existing condition, or an arise in new problems. I strongly advise against purchasing any self-treatment of any types to self-medicate without first undergoing a thorough consultation with a TCM practitioner.”
