Yes your OPG looks fine as no significant amount of bone loss is appreciated.
I don't think your tooth will be mobile or loose as that might just be normal physiologic mobility of the teeth.
The gum swelling might take another 2 weeks time to subside completely.
Continued using the gum paint and mouth wash prescribed.
Next Steps
If u still find your teeth is still mobile u must visit your dentist and get a check-up done once again. Doctor may split your teeth for few weeks if it's necessary.
Health Tips
Take Tab Doxycycline 100 mg if u have bleeding gums along with swollen gums.
Use warm saline rinses 4-5 times daily for atleast 15 days
Continue using the gum paint and use the mouthwash regularly after each oral intake( take 5-10 ml of Mouthwash keep it for atleast 2 min and rinse thoroughly then spit it and avoid any oral intake for next 20-30 minutes not even plain water or even do not rinse with plain water )
