You will likely experience some some pain, swelling, and bruising after surgery, which will decrease over the course of several days.
If the incision was made inside your mouth, maintaining good dental hygiene along with regular mouth washing will be extremely important during your recovery.
In most circumstances all the stitches are self-dissolving so will not need to be removed.
If you are considering a cheek or chin implant, then it is important that you are informed of the potential risks, complications and side effects of this surgery.
While all care is taken to minimise or totally avoid these complications and side effects, complications may and do occur despite the best medical care. It is important that you carefully read and understand the risk factors and they will be discussed in more detail when you have your consultation with your surgeon.
