Health benefits of saltwater rinses

Saltwater rinses stop growth of bacteria in your mouth

Saltwater rinses can help prevent germs from growing in your mouth. They reduce bacteria’s ability to flourish in an acidic environment.

Since harmful pathogens prefer an acidic environment, once neutralised, the mouth can become less irritated and healthier.

A research found that when used in conjunction with normal plaque management, saltwater rinses are efficient at reducing dental plaque and oral bacteria count..

Help in the healing process after dental procedures

After dental treatments such as tooth extractions, saltwater rinses contribute towards the process of recovery.

Because saltwater encourages gingival fibroblast migration and a rise in extracellular matrix components, which help to control wound repair activity, it aids healing following dental operations. Saltwater doesn’t really irritate the soft tissues of the mouth, nor does it burn or induce pain in the mouth.

Using saltwater rinses can also help to prevent uncomfortable dry sockets (alveolar osteitis) after extractions.

Respiratory health benefits
