Hello, Welcome Thanks for consulting HCM,
I have gone through your query, you have mentioned that you have difficulty in swallowing saliva, dont worry it can be due to
Tonsillitis,
You can take medications for that One Tablet
Cefixime 250mg twice daily, One Tablet
Cetrizine twice daily, One Capsule vitamin B complex once daily for three days
Do warm saline gargle two - three times a day
For Orthodontic treatment you are taking , you should consult your
dentist , and get it checked that for sharp edges ,
If problem continues then consult ENT surgeon.
Hope this will help you.
