Has anyone had sinusitis after contouring surgery and had to clean their mouth?

It's been almost a month since the surgery, and I've only taken 3 handfuls of antibiotics,
 but there 's no
 
improvement. I have headaches, toothaches, and the pus that keeps coming out...
 
I've not only used one antibiotic, but I've now changed it 3 times and
 changed from plastic surgery to otolaryngology.
 
Looking at the posts here, I see people who have had their washes often. Is it effective??

Did it happen again..??

In fact, is the swelling enough to require another cheek surgery??

First of all, the right side is clean, so I'm going to open only the left side and request cleaning...
