When you do, the air you breathe in drys the saliva in your tongue and mouth; this is what leads to bad breath after sex.

Dry mouth simply means the loss of saliva in the mouth. In the absence of saliva, the mouth emits an offensive odour.

The saliva is there to clean and wash the mouth. That is why when you feel your mouth is dry, you swallow some saliva.

The saliva is a slightly alkaline liquid secreted into the mouth by the salivary glands and mucous gland, consisting of mucin, protein and enzymes.

Strong foods when chewed mixes with saliva and it is easily broken down and swallowed in the mouth.

The following are functions of saliva;

  1.  Saliva helps in maintaining the mouth’s ph. Saliva is filled with various ions, some are salivary proteins which prevents precipitation, and would form a salt. The ions help in keeping the acidity of the mouth in a certain range.
  2. Saliva Contains EGF. It results in cellular proliferation and survival. EGF salivary is also regulated by dietary inorganic iodine, also plays an important role in maintaining gastric tissue integrity.
  3. Digestion: The function of saliva includes moistening food and helping to create food bolus. The saliva contains the enzyme called ptyalin which is capable of breaking down starch into simple sugar such as dextrin and maltose that can be further broken down in the small intestine.
  4. Role in Taste: Your saliva is very important in the sense of taste. It is the liquid medium in which chemicals are carried to taste receptor cells. People with a shortage of saliva often complain of dysgeusia which is reduced ability to taste, or having bad breath taste, metallic taste all the time. A very rare condition that affects the taste is ‘Saliva Hypernatrium‘ which is an excessive amount of sodium found in the saliva which is not caused by another condition like ‘Sjogren Syndrome’ that causes everything to taste salty.
  5. Lubricant: Mouth sores are very common with people with reduced saliva and food (mostly dry foods) sticks to inside the mouth. Saliva coats the oral mucosa by protecting it from trauma when swallowing, speaking and eating. In a nutshell, the saliva contributes immensely to oral hygiene maintenance. Without it, the amount of dental caries, periodontal diseases, cavities and other oral problems increases significantly.
