I just got my wisdom tooth out yesterday and was told to do saltwater rinses 4 times a day to keep it clean, how does saltwater work to clean and sterilize?
In: Chemistry
Its not sterilizing. It is helping you clean the area, basically just by mechanical action. Removing coagulated blood, dead cells, bacterial biofilms, etc. Making it be a less hospital environment for anaerobic bacteria.
Salt water in the right concentration (isotonic) is actually gentler on wounds than pure water is.
