Salt Water Rinse Benefits Oral Health

Mouthwashes are very helpful to cleanse your mouth and freshen your breath that toothbrushes cannot do. However, salt water rinses are generally affordable and can be equally effective in improving your oral hygiene. 

Salt water rinses can kill many types of bacteria via osmosis, meaning it removes the water from the bacteria. This results in the loss of water from the bacteria cell, thereby causing cell death or retarded growth, making it dead. Hence they are a good guard against infection after most dental procedures.

Did you know that the medicinal use of salt dates back to 1600 B.C? The health benefits of salt have been recorded in some of the world’s oldest medical scripts. 

It was believed that salt could dry out and even disinfect minor wounds. Most ancient Egyptian medicine prescribed anti-infective solutions, which contained salt as a base ingredient.

These solutions were applied as an ointment, administered orally, or used as a suppository (a solid medical device designed to be inserted into the rectum to dissolve). Greek medicine also used a mixture made of honey and salt to create a topical application to disinfect cuts and wounds.

The benefits of salt are discussed below, along with the procedure to make and use them.

Health Benefits of Salt Water Rinses

According to the Oral Cancer Foundation, most mouthwashes have a high alcohol content that can irritate your mouth, particularly your gums.

Salt is chemically a mineral composed of sodium chloride or NaCl. Rinsing your mouth with a NaCl solution is an ancient remedy. The salty rinse not only promotes healthy gums but encourages recovery from mouth ulcers as well.

Salt water rinses are safer alternatives as they instantly kill germs and bacteria and keep your mouth clean. When plaque on teeth interacts with high doses of sugary foods and beverages, it creates acids that attack your tooth enamel.

Plaque build-up for a longer period could contribute to gum disease. Your dentist might suggest that you frequently rinse your mouth using salt and warm water in such a scenario. This is because salt is known for its natural healing properties.

1 Salt water rinses stop the growth of bacteria

The salt water rinses can help stop the growth of bacteria in your mouth. This happens because the salt helps to cut down on the acidic environment that allows bacteria to thrive.

In simple terms, saltwater rinse works by increasing the pH balance in your mouth. This creates a much more alkaline oral environment, thus making it difficult for the bacteria to survive. The harmful bacteria in your mouth prefer an acidic environment. So as the saltwater neutralizes, your mouth can become less inflamed and healthier.

Where bacteria thrive, it gives rise to different problems. When you use a salt rinse, the bacteria find it difficult to grow spores that generally thrive and breed in your mouth. It is these bacteria spores that lead to a sore throat and sickness.

A 2017 study proved that salt water rinses effectively decrease dental plaque and oral microbial count when used alongside routine plaque control methods.

2 Help in the healing process after dental procedures

Salt water rinses aid in the healing process, especially after your dental procedures like tooth extractions. This is probably because it promotes gingival fibroblast migration and an increased amount of extracellular matrix components that help regulate your wound repairing activity.

A 2019 research found that gargling with saline water as well as nasal irrigation might be helpful in providing protection against the common cold and flu. Similarly, another study confirmed that salt water gargling could effectively reduce upper respiratory infections within a couple of days. 

The experts also suggested that it can provide potentially safe and effective intervention for people diagnosed with COVID-19 after contracting the SARS-CoV-2 virus.

4 Fights bad breath

If your teeth are sensitive to traditional alcohol-based mouthwashes, salt water rinse could be a cheap and natural alternative for fresh breath.

The salt water can fight off oral bacteria responsible for everything from gingivitis to bad breath. Swish with salt water immediately after lunch or your coffee break, and enjoy a fresh breath. Many individuals are not able to bear the intense sting of alcohol-based mouthwashes and so prefer salt water mouthwash.
