Nothing is ever TRULY necessary, I'm sure plenty of people have fully healed with no aftercare at all--the question is will you and do you care? Saline rinses are the best way to help clean the extraction sites since you can't brush or use mouthwash at first (mouthwash until much later). Saline is a natural disinfectant. It's easy to make, just buy some non-iodized sea salt (specifically) and add enough salt to a mug of boiled or hot distilled water (around 1 tsp) so that it's no saltier than a potato chip. Don't have to rise long, usually 30 sec-1min
