Some people are born with a poor sense of smell or taste. Upper respiratory infections are blamed for some losses, and injury to the head can also cause smell or taste problems.
Natural remedies used in the treatment of bad breath include chewing on mint or parsley. If bad breath is due to a health problem such as a sinus infection, diabetes, acid reflux (gastroesophageal reflux disease, or GERD), etc., then the underlying medical issue needs to be treated. If bad breath is a side effect of taking a medication, discuss with a health care professional whether other options for medication can be taken. Never stop taking a medication without first consulting your health care professional.

Chewing food increase saliva production, so when you are skipping meals or dieting, you can develop bad breath. A diet low in carbohydrates or any restrictive diet may increase your chances of bad breath. It is always good to drink plenty of water to keep you hydrated and to help maintain a good level of saliva in your mouth.
If your dentist determines that your mouth is healthy and that the odor is not oral in nature, you may be referred to your family physician or to a specialist to determine the cause of the odor and possible treatment. If the odor is due to gum disease, your dentist can either treat the disease or refer you to a periodontist, a specialist in treating gum tissues. Gum disease can cause gum tissues to pull away from the teeth and form pockets. When these pockets are deep, only a professional periodontal cleaning can remove the bacteria and plaque that accumulate.
