I usually advise my patients to stay away from mouth wash for 2 days. I usually do not have them rinse at all for atleast the first 24 hours. This is because you want to protect the blood clot that forms after having a tooth extraction. The blood clot is not very stable for the first 24 hours and if you lose it, you wind up with dry socket. Generally you don't want to spit anything out of your mouth or use a straw or smoke because the pressure can dislodge the blood clot. After this period, you will can start rinsing but it is more advisable to use warm salt water.
Best of luck to you!
