Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain and presentation of symptoms swollen papillae as well as
swollen gums and sore teeth are all due to inflammation of the mucosal surfaces of mouth leading to
STOMATITIS and it can be due to
allergic reaction to any of the constituent of mouthwash leading to inflammation.
The bump at the piercing site is due to injury to the soft tissues caused by the piercing probe and it leads to inflammation and bump formation as well as swelling of the papillae is also due to inflammation...
Nothing to worry, just change the mouthwash that you are using and you can use
Chlorhexidine containing alcohol free mouthwash.
Take anti-inflammatory painkiller like
Ibuprofen.
Do warm saline gargles.
Suck on ice pops and gargle with cold water for reducing inflammation and resolution of bumps.
For soreness of gums and teeth gargle with a numbing mouthwash containing Lignocaine especially during meals to relieve discomfort.
Hope this information helps..
Thanks and regards.
