Halitosis refers to persistent bad breath and is a very common problem that may occur due to many causes, most usually the build-up of bacteria (plaque) that coat the teeth, gums and tongue.
Frequent causes of bad breath include:
- Dental problems like cavities and gum disease
- Dry mouth (xerostomia)
- Infections affecting the mouth, nose and throat
- Other chronic health conditions
In certain cases, you may be referred to a periodontist to treat underlying problems affecting your teeth and gums that lead to halitosis.
It is important to practice good oral hygiene consistently to prevent bad breath. Your dentist can help by prescribing you mouth rinses and specially formulated toothpastes that contain antibacterial agents designed to kill bacteria and reduce build-up of plaque on your teeth.
