Hi..
Can understand your concern..
As per your query if the infection reversed again there must be still some food entrapping in that area and causing infection..
You can continue with the oral rinses and flossing and try to keep that area clean by gargling after each meal and with plane water whenever you eat anything..
Other thing that you can do is that you can visit a general
dentist and just get cleaning of that area if you have less time so that the source of infection will be removed and you will get relieved until you come back from Canada..
A general dentist can very well clean your gums and can give you antibiotic medicines like
metronidazole as well as gum paint so that you can have a pleasant and infection free time in canada..
Brush your teeth twice a day once in morning and other before sleeping..
Keep yourself well hydrated..
Taking
Vitamin C containing lozanges are very good for gum health.. One a day should be taken..
Doing all this will be very helpful till you find time to come back and consult a periodontist..
Hope your query is solved..
Thanks and regards..
