Bad Breath clinically termed Halitosis is a common problem resulting mostly from poor oral hygiene. It could either be occasional or be a chronic condition. It could also be an indication of other underlying health problems and can be made worse by certain types of foods.


  • Bad breath can have a number of causes though it is mostly because of the buildup of bacteria in the mouth. This is due to poor oral hygiene as food particles are left in the mouth that decay and cause bad breath.

  • Food such as garlic, onions etc have a strong odour which does not go away inspite of brushing and flossing. It is eventually carried off to your lungs and breath. The smell remains until the food has passed out of your body completely.

  • Tobacco products – Smoking or use of tobacco products can cause bad breath and lead to problems such as periodontal disease.

  • Health problems- such as bronchitis, sore throat, sinus infections, lactose intolerance, diabetes, other gastro intestinal problems, some kidney and liver problems may also cause bad breath.

  • Dry Mouth- a condition that is caused by problems with salivary glands or the connective tissue disorders or due to medications may cause bad breath. Saliva helps to moisten and cleanse the mouth thus removing bacteria that cause bad breath.

  • Mouth infections such as gum disease, impacted tooth or cavities may cause bad breath

  • Dentures and braces if not cleaned properly can cause bad breath due to rotting of food and accumulation of bacteria.

  • Medications such as antihistamines or diuretics can cause dry mouth condition that may lead to bad breath.

  • Morning bad breath is caused due to very less production of saliva at night.
