You just had orthognathic surgery. This is treatment that reshapes the jaws to improve their form and function. Your job now is to keep yourself comfortable and help your body heal quickly. Make sure to get plenty of calories and protein. Get up and move around, but avoid strenuous activity. Be sure to get lots of rest. Keep your mouth and teeth clean to help the incisions heal.
For the first few days, swelling will likely increase. It should then start to ease. To reduce swelling and pain:
Sit or lie with your head and shoulders higher than your heart.
Apply an ice pack to your face for 10 minutes at a time, with breaks of at least 5 minutes in between. Keep a thin cloth between the cold source and your skin.
Use pain medicines as directed.
You will need to get enough nutrition, which may be harder while you’re not able to chew. You also need fluids to help prevent dehydration and nausea. For calories, protein, and fluids, try total-nutrition drinks, protein powders, soups, milk shakes, and other blended foods. Don’t use a straw, since the suction can stress the incisions in your mouth. Instead, use a glass or a “sippy cup” designed for young children. Once you can chew again, eat soft foods that can be cut with a spoon or fork. As you heal, you’ll gradually return to your normal eating habits.
To keep your teeth as clean as possible:
If you can’t open your jaws, brush the front surfaces of your teeth with a baby toothbrush.
If a fluoride toothpaste or mouth rinse is prescribed, use it as directed.
If your surgeon advises it, start using an oral irrigator about 10 days after surgery.
Aim to get back to brushing and flossing normally as soon as you can.
If you have any of the following problems, call your surgeon:
Pain that can’t be controlled
Nausea or vomiting that can’t be controlled
Swelling that continues to worsen after 3 to 4 days
A fever of 100.4°F (38°C) or higher
Go to the emergency department if your health care provider’s office is closed.
