From birth, the human oral cavity contains millions of bacteria. These bacteria maintain the pH of our oral cavity, help our digestion, and are always “with us”.
This also means that in no situation can we make our oral cavity sterile (completely germ-free).
During tooth extraction an open wound is created in the oral cavity, which bacteria in the oral cavity can infect and cause inflammation iforal hygiene is not maintained properly.
To prevent this, you should brush your teeththoroughly before tooth extraction and rinse with an antiseptic mouth rinse for 30-60 seconds.
