* BANA test: This measures levels of a specific enzyme produced by halitosis-causing bacteria.
* Beta-galactosidase test: Levels of the enzyme beta-galactosidase have been found to correlate with mouth odour.
The dentist will then be able to identify the likely cause of the bad breath.
TREATMENT
The best method to reduce halitosis is good oral hygiene. This ensures that cavities are avoided, and reduces the likelihood of gum disease.
It is recommended that individuals visit the dentist for a check-up and cleaning twice a year. The dentist may recommend a toothpaste that includes an antibacterial agent, or an antibacterial mouthwash. Alternatively, if gum disease is present, professional cleaning may be necessary to clear out the build-up of bacteria in pockets between the gums and teeth.
HOME REMEDIES
Other lifestyle changes and home remedies for bad breath include:
* Brush the teeth: Be sure to brush at least twice a day, preferably after each meal.
* Floss: Flossing reduces the build-up of food particles and plaque between the teeth. Brushing cleans only around 60 percent of the surface of the tooth.
* Clean dentures: Anything that goes into the mouth, including dentures, a bridge, or a mouth guard, should be cleaned as recommended on a daily basis. Cleaning prevents the bacteria from building up and being transferred back into the mouth. Changing toothbrushes every 2 to 3 months is also important for similar reasons.
* Brush tongue: Bacteria, food, and dead cells commonly build up on the tongue, especially in smokers or those with a particularly dry mouth. A tongue scraper can sometimes be useful.
* Avoid dry mouth: Drink plenty of water. Avoid alcohol and tobacco, both of which dehydrate the mouth. Chewing gum or sucking a sweet, preferably sugar-free, can help stimulate the production of saliva. If the mouth is chronically dry, a doctor may prescribe medication that stimulates the flow of saliva.
* Diet: Avoid onions, garlic, and spicy food. Sugary foods are also linked to bad breath.
Reduce coffee and alcohol consumption. Eating a breakfast that includes rough foods can help clean the back of the tongue.
If breath odour persists despite controlling these factors, it is recommended that an individual visits a doctor for further tests, to rule out other conditions.
