While bad breath is humiliating, it can become seriously concerning when it begins to smell like feet. Usually, germs, bad dental hygiene, or even some medical conditions are to blame for this peculiar smell. Explore the causes of this disagreeable smell and your options for dealing with it.

Foot-Smelling Breath Causes

1. Overgrowth of Bacteria

• Millions of bacteria live in our mouth, and some of them emit sulfur compounds that smell bad.
  
• Food particles cause scents similar to stinky feet when they are broken down by bacteria.
  
• Bad dental hygiene makes it easier for bacteria to grow, which makes the smell worse.

2. Sinus Infections and Post-Nasal Drip

• Mucus from sinus infections can drip into the back of the throat, creating a breeding ground for bacteria.
• Sweaty socks can be the smell of the bacteria that feed on mucus.

3. Xerostomia or Dry Mouth

• Saliva helps with the removal of food particles and microorganisms.
• Bad-smelling bacterias grow well in the ideal conditions created by a dry mouth.
• Dry mouth can come from taking medicines, dehydration, or sleeping with your mouth open.

4. Oral Thrush or Fungal Infections

• Bad breath with a cheesy or foot-like smell can come from an overabundance of oral yeast.
• It frequently manifests as white spots on the inner cheeks or tongue.

5. Bad Dietary Decisions

• Strong & disagreeable breath can result from ketosis, which is caused by high-protein, low-carb diets.
  
• Foods that leave an unpleasant odor in the mouth include dairy products, onions, and garlic.

According to the American Dental Association, 90% of bad breath cases originate from the mouth due to bacterial activity. Volatile sulfur compounds (VSCs), such as hydrogen sulfide and methyl mercaptan, are the main culprits behind the foot-smelling breath.

2. Stay Hydrated
