What is bad breath?

Bad breath, also known as halitosis,  can be embarrassing and can affect a person’s social interaction and self-confidence.  Bad breath refers to an unpleasant odor from a person’s mouth when they exhale or speak.

What causes bad breath? 

1.  Bad breath is often caused by the presence of bacteria in the mouth. These bacteria break down food particles, plaque, and other debris, releasing foul-smelling gasses as a byproduct.  This can be linked to some of the following:

  • Poor oral hygiene: Not brushing and flossing adequately can leave behind food particles and bacteria in the mouth which can cause unpleasant odors.
  • Gum disease: Persistent bad breath can be resulting from periodontal disease (commonly known as gum disease). Bacterial infection in the gums can produce foul-smelling gasses.
  • Dry mouth: Saliva plays a crucial role in rinsing away bacteria and food particles. Reduced saliva flow can result in dry mouth, leading to bad breath. Dry mouth can be caused by certain medications, mouth-breathing, salivary gland problems, or dehydration.
  • Food and drinks: Consuming certain foods with strong odors, such as garlic, onions, and spices, can cause temporary bad breath. Additionally, beverages like coffee and alcohol can contribute to bad breath.
  • Tobacco use: Smoking and other forms of tobacco use can lead to persistent bad breath, stain teeth, and increase the risk of gum disease.
  • Mouth infections: Oral infections, such as dental abscesses, can cause bad breath due to the presence of bacteria and the release of pus.
  • Dentures and oral appliances: Ill-fitting dentures or oral appliances can trap food particles and be a perfect place for bacteria, leading to bad breath.
  • Tonsil stones: Tonsil stones are small, calcified deposits that form on the tonsils. These stones can harbor bacteria and emit an unpleasant odor.

2. Bad breath can also be a symptom of a certain underlying medical condition. Some of these examples include:

  • Sinusitis: Inflammation and infection in the sinuses can result in postnasal drip, leading to bad breath.
  • Gastroesophageal reflux disease (GERD): Acid reflux can cause stomach acid to flow back into the esophagus, resulting in an unpleasant taste and odor.
  • Diabetes: Uncontrolled diabetes can lead to a fruity or sweet-smelling breath due to the presence of ketones in the body.
  • Kidney disease: Impaired kidney function can cause a buildup of waste products in the body, leading to a metallic or ammonia-like breath odor.
  • Liver disease: Certain liver conditions, such as cirrhosis or hepatitis, can cause a distinctive, musty breath odor.
  • Respiratory tract infections: Chronic infections in the respiratory tract, such as chronic bronchitis or lung abscess, can contribute to bad breath.
  • Xerostomia: Chronic dry mouth, often as a side effect of medication or as a symptom of an underlying medical condition, can result in bad breath.

3. Certain diets or eating patterns can contribute to bad breath. It’s important to note that these dietary factors may contribute to bad breath temporarily, and the effects can vary among individuals. Maintaining good oral hygiene, staying hydrated, and following a balanced diet can help minimize the impact of these dietary factors on breath odor. If you have concerns about your breath, it’s advisable to consult a healthcare professional for proper evaluation and guidance.  

  • Low-carb or ketogenic diets: Diets that are very low in carbohydrates or follow a ketogenic approach can lead to a condition called “ketosis.” When the body doesn’t have enough carbohydrates for energy, it starts breaking down fat for fuel, producing ketones as a byproduct. Ketones can be released through the breath, resulting in a distinctive fruity or acetone-like breath odor.
  • Crash diets or fasting: Rapid weight loss diets, crash diets, or prolonged fasting can cause the body to break down fat stores for energy, leading to the production of ketones and potentially causing bad breath.
  • High-protein diets: Diets that are excessively high in protein and low in carbohydrates can also contribute to bad breath. When the body metabolizes protein, it produces ammonia as a waste product, which can be released through the breath, causing an unpleasant odor.
  • Skipping meals or irregular eating patterns: Extended periods without eating can lead to a dry mouth and reduced saliva flow. This dry environment allows bacteria to thrive, leading to the potential for bad breath.
  • Excessive consumption of pungent foods: Diets that include excessive amounts of strongly aromatic foods, such as garlic, onions, spices, or heavily seasoned foods, can contribute to temporary bad breath.

What are some tips and remedies in eliminating bad breath?

To help with bad breath, consider the following tips:

  • Maintain good oral hygiene: Brush your teeth at least twice a day with fluoride toothpaste and use dental floss or interdental cleaners (Waterpik) to clean between your teeth. Replace your toothbrush every three to four months or sooner if the bristles become frayed.
  • Scrape or brush your tongue: Bacteria can accumulate on the surface of the tongue and contribute to bad breath. Use a tongue scraper or your toothbrush to gently clean your tongue on a daily basis.
  • Use mouthwash: Rinse your mouth with an antimicrobial mouthwash or an alcohol-free mouth rinse to help kill bacteria and freshen your breath. Look for mouthwashes that contain ingredients like chlorhexidine, cetylpyridinium chloride, or essential oils like menthol or eucalyptol.
  • Practice proper denture or oral appliance care: If you wear dentures or use oral appliances like retainers or mouthguards, make sure to clean them thoroughly to avoid the buildup of bacteria and odors.  If you have ill fitting appliances, see your dentist for adjustment and evaluation for remake. 
  • Consider using a nasal rinse: If you have postnasal drip or sinus issues contributing to bad breath, using a saline nasal rinse can help clear mucus and reduce odor-causing bacteria in the nasal passages.
  • Stay hydrated: Drink plenty of water throughout the day to help maintain saliva flow. Saliva helps cleanse the mouth and neutralize acids produced by bacteria, reducing the risk of bad breath.
  • Avoid tobacco products: Smoking or using other tobacco products can contribute to bad breath. Quitting tobacco not only improves your breath but also benefits your overall health.
  • Limit odorous foods and beverages: Reduce consumption of strongly aromatic foods like garlic, onions, and spices, as well as beverages like coffee and alcohol, which can contribute to bad breath.
  • Eat crunchy fruits and vegetables: Snacking on crisp fruits and vegetables like apples, celery, and carrots can help stimulate saliva production and naturally cleanse the mouth.
  • Chew sugarless gum or mints: Chewing sugarless gum or using sugar-free mints can stimulate saliva flow and temporarily mask bad breath. Look for products that contain xylitol, which can help reduce bacteria in the mouth.
  • Try natural remedies: Some natural remedies may help freshen breath. Chewing on fresh parsley, mint leaves, or cloves can provide a temporary improvement in odor. Green tea or herbal teas with antibacterial properties, such as peppermint or chamomile, may also help reduce bad breath.
  • Visit your dentist regularly: Schedule regular dental check-ups and cleanings to maintain oral health and address any underlying dental issues that may contribute to bad breath such as gum disease, dry mouth, cracked fillings and failing old crowns.
  • Manage underlying conditions: If your bad breath is caused by an underlying medical condition, such as diabetes, gastroesophageal reflux disease (GERD), or respiratory infections, it is important to work with your healthcare professional to manage and treat the condition effectively.
  • Reduce stress: Stress and anxiety can contribute to dry mouth and worsen bad breath. Engage in stress-reducing activities like exercise, meditation, or hobbies to help manage stress levels.

It’s important to note that occasional bad breath is normal.  If bad breath persists despite good oral hygiene practices, it is advisable to consult a dentist or healthcare professional to identify and address the underlying cause. It’s important to note that bad breath alone is not necessarily indicative of a serious medical condition. However, if you have persistent bad breath that cannot be attributed to poor oral hygiene or dietary factors, it is advisable to consult a healthcare professional for further evaluation and appropriate diagnosis.
