Most patients do not experience pain during the procedure as they are usually under a local anesthetic (meaning you are awake but the area is numbed). Additionally, the bone where the implant is placed does not have nerves that sense pain.
After the surgery, you may experience some discomfort in your chin, cheeks, or under the eyes. Over-the counter pain relief is generally recommended to manage this pain but always consult with your doctor before taking medication. You can also rinse with salt water for relief or use an ice pack to reduce swelling.
