Ask about (and have them give you written instructions) on compressing the area with ice and or hot packs. There’s a specific method that really helps reduce any swelling that you might have in your cheeks. If possible, have someone come over and help you by timing the packs exactly as they tell you. My mom was a nurse and insisted on coming over to do this for me. I was amazed and so was the dentist because I had no visible swelling or bruising on my cheeks and it healed much faster. I had all four of them out at the same time and the oral surgeon said I should have had swelling.
They also gave me a prescription painkiller but told me to take Motrin first and see how I did. I didn’t need the Rx. I did the same for my son (on the packs and the medicine) and he had the same results.
They usually have a printed advice slip. Follow it to the letter.
