Hi, You can use bags of frozen vegetables for ice packs- they are cheap and reusable. Also rinse several times a day with a solution of warm salt water. It will help with the healing of your gums and also soothe the wounds. The whole thing is quite taxing physically so be sure to get plenty of rest. With the ice packs-20 minutes on, 20 minutes off.
About the mental stuff, that takes the longest. Don't get down on yourself or worry about what others might think. Once you are all settled in with your new teeth it is doubtful anyone will know. Just like any other part of the body, teeth get sick and have to be removed. You are doing this for you- no one else. Stay positive and stay focused.
