Swelling after apicoectomy? It is almost 3 weeks I was bit wondering how long does it take swelling to go away completely.

I had apicoectomy for 5 and root canals for my 6 front teeth. It took almost a week for the swelling to go away. But I can feel there is little swelling around my chin I can find the difference. I'm still having stitches the doctor said they are Dissolving sutures. It is almost 3 weeks I was bit wondering how long does it take swelling to go away completely.
