Unpleasant odor from the mouth; halitosis
Unpleasant smell from the mouth is known and under a different name – halitosis. This condition can be temporary or last for a long time, depending on the cause.
In the oral cavity, millions of bacteria live, especially on the back of the tongue. In many people, these bacteria and the products of their vital activity are a source of bad odor. Wet warm conditions of the oral cavity are an ideal medium for the growth and reproduction of these bacteria. In most cases, the cause of bad smell should be sought directly in the mouth.
In some cases, bad breath should not be regarded as a sign of any health problems. As an example, you can consider unpleasant odor from the mouth in the morning. This is due to some changes in the oral cavity at the time while you are sleeping. During the day, the saliva cleanses the decaying remains of food and an unpleasant odor. At night, the body produces less saliva. Your mouth dries up, and the dead cells adhere to the tongue and inner surface of the cheeks. Bacteria feed on these cells and, as a result, give off an unpleasant odor.
What causes unpleasant odor from the mouth:
Bad oral hygiene – If the teeth are not regularly or badly cleaned, this allows the food particles to get stuck between the teeth and decompose, giving off an unpleasant odor. Poor oral hygiene, ultimately, leads to the development of gum disease (periodontitis).
Infections in the oral cavity – This condition can be caused either by a cavity in the tooth, or by gum disease.
