After wisdom teeth removed is salt water rinse helpful?

Yes: You should start rinsing with warm salt water 24 hours after the surgery and continue until you see your oral surgeon for follow up.

Maybe:: If your blood pressure is not under control, or if the bleeding has not completely stopped it may not be a good idea to rinse with salt water. Discuss this with you surgeon first. The warm salt water rinse will speed up healing and is typically safe to use after 24 hours in most other cases.
