 How to prevent and treat bad breath


 Bad breath makes you not confident in communication and life

Answer:  Bad breath (halitosis), or foul-smelling breath is common in many men and women. Bad breath is not serious, but it affects the attitudes, behaviors and psychology of communication, affecting both the work of the patient.

The Reasons of halitosis

1. Teeth - mouth

Odor is from sulfur-derived chemicals such as hydrogen sulfide, methyl mercaptan, dimethyl sulfide. These sulfides are due to the breakdown of proteins by oral micro-organisms, in the following cases: 

- When food left in the mouth or between teeth is separated by bacteria, it produces a foul odor. 

Infections in the gums, tooth roots, around the neck ... 

- Many deep teeth have broken in the pulp or dental cavities are convenient for bacteria to shelter, proliferate and cause disease. 

- Plaque attached to the root is a good environment for bacteria to enter and bring to bad breath. 

Tongue inflammation and food sticking to the surface of the tongue or grooves of tongue cracking is a good environment for bacteria to break down proteins that create odors.

Mouth dry when saliva is reduced. Saliva is responsible for keeping the cheek, tongue, lips, moisturizer, saliva in yeast helps digestion, reduce pH changes in the mouth. When acidity is high, bacteria multiply. 

There are several causes for dry mouth: salivary gland dysfunction, facial nerve paralysis (nerve 7), oral breathing due to nasal congestion or by habit, in the elderly, menopause or in diseases General disorders such as diabetes, neurological disease, postoperative radiotherapy of head and neck area ... 

Some medications such as hypotension, tranquilizers, anti-allergy medications, dysmenorrhea, depression, schizophrenia, amphetamines , diuretics ... also reduce saliva in the mouth. 

Most cigarettes are strong cigarettes such as cigars, pipes, and pipes that also reduce saliva to odors from the mouth.

2. Nose - sinus

Sinus sinusitis, chronic sinusitis, sinusitis, especially sinusitis caused by bad breath, even cause discomfort to people around him when approaching.

Nausea nasal polyps, such as nasal polyps, cancer, papillary neoplasia, also cause bad breath.

The ear nose is the small child that causes bad breath or foul odor on one side.

Seborrheic seborrhea in the nose. This usually causes foul smelling when the patient develops nasal congestion or nasal discharge to the nasal glands in the nasal or nasal opening to open out nose foul. Rarely, people around smell this odor.

6. Chronic diseases

Methods of measuring bad breath

Objective: Patient sitting opposite the examiner, nose covered by mouth breathing for a few minutes. If there is a smell, the source is from the mouth. Then the patient sucked his nose out. If you smell from both your mouth and nose, it can be due to a general illness. 

+ Subject: The patient feels himself by exposing his hand to his mouth and then smelling it.

Patient or examiner smells on dental floss after tooth decay. 

+ In some modern dental clinics and dental clinics, it is possible to measure the level of foulness in the mouth with Halimeter, Halitest also applies.
