Post-operative care is important for a smooth recovery after oral surgery. It typically involves keeping the surgical area clean to prevent infection, which may include gentle rinsing with a saltwater solution or a prescribed mouthwash. It's important to avoid vigorous rinsing or spitting to prevent dislodging any blood clots at the surgery site. Additionally, you should refrain from smoking and drinking through a straw, as these actions can hinder the healing process.
