Should i do the salt water rinse after a wisdom tooth extraction?

Yes, gently: Salt water rinsing can be helpful, as long as you rinse gently... You do not want to disturb the extraction site as a dry socket can occur if the blood clot is disturbed. Be very gentle with yourself.

Not in the 1st 24hrs: Wait until the 2nd day if not longer after the extractions until start rinsing with salt water.

After 24 hours: You should not do any rinsing, spitting, or drinking through straws for the first 24 hours after the extraction. The day following the extraction you should gently rinse with warm salt water several times a day especially after meals.

Absolutely!: No rinsing is done for the first 24 hours after the extractions are completed. Then the day after extractions, start the warm salt water rinses. Put a teaspoon of salt in a juice glass of warm water. Swish for 1-2 minutes and then spit out gently. Do this 3-4 times a day for a few days. These rinses help to soothe the sore gums and promote their healing at the extraction sites.
