hello and welcome to hcm forum Ryan,
i am glad you posted your query, first of all, i would like to inform you that as the
abscess has been drained by your
dentist therefore you need not worry, as most of the infection(pus) must have discharged by now, but as a normal defense mechanism of our body,
fibrosis starts in order to repair the damaged tissue, which gives a firm consistency to the affected area.
i hope you are on antibiotics till the time swelling completely subsides, but if not, start with a 7-10 days antibiotic and anti-inflammatory medication.
also, try warm saline rinses(3-4 times/day),
use an antibacterial(
betadine) mouth wash (2 times/day)to hasten the healing process.
do not worry, the swelling will subside.
remember to have regular follow ups with your dentist until swelling goes off completely,
i wish you good health.take care.
