I hope that goes well!!
There is nothing to be afraid I assure you, the people that are working on you are trained professionals!
Here are some tips that may help you after you get it done
Watch what you eat: Stick to a diet consisting of liquids right after your surgery. Add solid foods back gradually, starting with softer foods, like pudding. You should stay away from spicy or hot foods and avoid straws.
Rest as much as possible: You’ll want to rush through your recovery and return to your normal life as quickly as possible, but for your long-term recovery take things slowly. Relax as much as you can with your head propped up by pillows. Do not do any light exercise for at least a day. Wait a few more days for any strenuous exercise or heavy lifting.
Rinse your mouth out with salt water: A salt water rinse can help reduce swelling and pain. By the second day, you can create your own mouth rinse out of salt and warm water. Rinse with this mixture several times a day, especially after eating or drinking.
Control bleeding with gauze and tea bags: Your oral surgeon will instruct you on to bite down gently on a piece of gauze to reduce bleeding. After 12 hours, you may want to switch to a damp tea bag instead. Tea leaves can help reduce pain and encourage clotting.
((However if you feel like something isn’t right I would call your dentist anyway)) xoxo
