Here’s how it exactly works:

Maintaining the pH:

Salt water can neutralize the effect of acids in the mouth which are formed as a result of bacteria in the sore throat and also drain away the infected mucus from the throat.

Salt absorbs:                                                                                  

The salt water  works by the method of osmosis, which is absorbtion of moisture. When in higher concentration than the inflammated tissues, it can draw out all the moisture content from them and provide relief from pain. The bacterial growth also dries up due to lack of moisture and eventually dies. And the infection subsides and relief is experienced.

Natural Disinfectant:

Salty environment prevents bacterial growth whereas warm water dislodges the food particles thus accelerating the healing. Highly recommended after 24hrs of wisdom tooth extraction or any surgical procedures.

Cleanses the Mouth:

Oral cavity is lined by mucus, this mucus can harbours both good and bad bacteria. The growth of bad bacterial can be curbed with gargling with salt water as it dissolves all the impurities and thus helps in eliminating the bacteria.

Bad Breath:

Some foods, medications or health issues often result in bad or smelly breath. Gargling with salt water is quick and easiest way to get rid of bad breath instantly.

Sore Throat:

Problems of sore throat or pharyngitis that causes inflammation and pain in the mouth can be treated for temporary relief by a salt water gargle. Problems of laryngitis, tonsillitis and other sore & sore throat problems can be treated with a salt water gargle.

Bleeding and swollen Gums:

If you are experiencing pain due to swollen gum problems like gingivitis, then a salt water gargle will provide relief from the inflammation and help in reducing infection.

Dental Plaque:

Salt water gargle can treat dental plaque, help in washing out impurities from the mouth, thwart bacterial growth and speed up the irrigating and healing process in the mouth.

Nasal Problems:

Gargling also targets the nasal cavity, draining out all the mucus and bacterial infection from it. The blood capillaries are irrigated and get dilated and hence all the congestion is released and the phlegm loosens up and flows out. Bronchitis troubles are also reduced and sinus infections and allergies are cleared.

Tongue Problems:

The white coating that forms on the tongue can be removed by gargling with salt water. Even burns on the tongue can be healed with a warm water gargle as it helps in reducing pain and inflammation, care should be taken to keep the salt content minimal to avoid a burning sensation.

For severe cases a doctor’s treatment is required.
