The stain reduction is likely a combination of certain bacteria that produce more oxidative products being allow to grow more effectively, and also due to a change in the stickiness of your teeth. When I say probiotics this does not mean you should drink Kombucha, since that stuff is a vinegar and will erode your enamel.
Patients are advised by to gently rinse the mouth with warm salt water 24 hours after tooth extraction surgery. Rinsing with salt water helps to clean and heal the site of the surgery.

The blood clot protects gum tissue and the mandible from further damage and infection. Dislodging the clot could cause unnecessary pain, lead to possible infection and lengthen the healing process.
