How do I get rid of food stuck in my tooth socket after an extraction? (Photo)

It depends on whether the retainers are well treated as well.

Yes, salt water is the best and safest irrigant to use after oral surgery. The best would be physiological saline solution at 0. 9% available at pharmacies. This should be syringed (with a blunt tipped needle) into the healing socket to dislodge debris. Rinsing the whole mouth tends to be less effective when the wound is new and deep. Your dentist should be able to demonstrate how this can be done safely. If you do not have access to commercially-available saline, then warm salt water that you make yourself can also be used.
