What is it?
The smell from the mouth is a very uncomfortable feeling. It is also known as halitosis. Bad smell may appear from time to time, or may be permanent depending on the cause.

With millions of bacteria live in your mouth, especially on the back of the tongue. To most people, these bacteria are the main causes of smell. The warmth of the mouth, wet conditions are ideal for their growth. Most stench is caused by something that is already in your mouth.

Some types of bad breath are considered to be normal. They usually do not pose health problems. An example might be “morning wind”. This occurs due to changes in your mouth during sleep. During the day, saliva washes away food tainted with odors. Our body produces less saliva at night. The mouth remains dry, and dead cells stick to your tongue and inside your pages. When bacteria feed on these cells, produces a heavy odor.

In addition, the smell can be caused by the following factors:

Poor dental hygiene – brushing and infrequent use of dental floss, which allows pieces of rotting food inside the mouth.
Infections in the mouth – periodontal disease (gum)
Respiratory infections – infections of the throat, sinus or lung.
External factors – Garlic, onions, coffee, tobacco.
Dry mouth (xerostomia) – Caused by salivary gland problems, medication or by “breathing with the mouth”.
Systemic diseases (general) -Diabetic, liver disease, kidney disease, lung disease, sinus disease, gastro-esophageal reflux and other.
Psychiatric Disorders – Some people notice the bad smell, but others do not notice. This is known as “pseudo halitosis”.

You can’t always know the presence of bad breath. This is because the nervous stimuli in the nose adapt to the smell. Others close to you may notice and react with turning their heads to the side when you talk.

Other symptoms depend on the causes of bad breath:

Poor hygiene – teeth are covered with a layer membrane or plate. You can have food left between the teeth or pale gums and swollenness.
Infections in the mouth – Symptoms depend on the type of infection. They include:
Redness in the gingiva’s or swollenness which may bleed easily, especially after washing your teeth.
Pus between teeth or pus pockets on top of the teeth
Moving teeth or changes in the placement of prosthesis
Open and painful sores in tongues and gums
Respiratory infections – Inflammation of the throat, lymph nodes, swollen throat, fever, nose occupied, cough mucus.
External causes – tobacco stains on fingers and teeth, stains on teeth by coffee
Dry mouth – Symptoms may include:
Barriers swallowing food
Obstacles during speech
Blisters in the mouth
High number of cavities
Dry eye (Sjögren’s syndrome)
Adjustments disease – Symptoms of diabetes, lung disease, kidney disorders or liver pathology.

Your dentist or doctor can see the bad smell during the visit to the clinic. Sometimes, the smell itself may suggest the cause of the problem. For example, “fruit smell” may be a sign of uncontrolled diabetes. “The smell of urine”, especially among persons with high risk for kidney disease, kidney failure.

Your dentist will review medical history for any condition that can cause bad breath and for any drug that causes drying of the mouth. Your dentist may also ask you for the way of nutrition, personal habits, and he’ll determine when and where the stench is coming from.

The dentist will examine your teeth, gingiva, mouth and salivary glands. He will examine your head and neck and the issuance of breath coming through the nose and the mouth.

The dentist can send you to your family doctor if any systemic disease is the cause of the problem. In severe cases of gum disease, the dentist may suggest you meet with periodontist (paradontolog, or a dentist specializing in the gums problems).

They will need diagnostic tests if the doctor suspects lung infections, diabetes, kidney disease, liver disease or Sjögren’s syndrome. The type of analysis will depend on the suspected disease. You may need blood tests, urine tests, x-rays of the chest or sinuses, or other tests.

The lasting of the smell will depend on the cause. If the problem results from poor dental hygiene, proper dental care will cool your mouth immediately. You will even have better results after cleaning your teeth regularly with the brush and floss. Periodontal disease and tooth abscess react quickly right after dental treatment. Bad smell caused by chronic sinusitis can return, especially if it is caused by structural changes of the sinuses.

Smell that is caused by general diseases can be a long-term problem. Often it can be controlled with proper medical care.

Bad smell caused by dental problems can be prevented easily with home care or professional care.

This means:

Cleaning the teeth, tongue and gums after each meal
Cleaning with teeth floss once a day
Rinsing with oral antiseptic
Regular visits to the dentist (at least twice per year).
You can also fight bad breath by drinking plenty amounts of water every day to produce as much saliva as possible. Other products such as:

Sugar free chewing gum
will help prevent the smell and prevent the formation of dental plaque.

Bad breathe treatment depends on the causes.

When should you call the doctor?
Call your dentist immediately if you notice smell, moving teeth or gums that painful and swollen. Also, contact your dentist if you have a bad odor associated with the following symptoms:

Sore throat
Postnasal secretion
Discoloric scretion from the nose
Cough with secretions
Even if you lack the above symptoms, you should call your dentist or doctor if you keep smelling despite good food and proper dental hygiene.

Sometimes the smell could be a sign of a medical condition that requires immediate attention. If you have diabetes, gastro-esophageal reflux disease or chronic liver disease or kidney, ask your doctor what to do about the smell caused by the disease you have.

From the moment the smell is diagnosed, the smell of fresh outlook is usually excellent if you are regular in the dental treatment plan.
