I think i now see a small pus on my gum where two teeth had root canal....i was told a yr ago there is infection there, but somehow because it didnt have a pus or anything, just what the xray showed, i just forgot about it...yesterday i noticed this small whitish spot, im worried, the periodontist can only see me one week from now, what should i do in the meantime, should i see a dentist just to drain it until i can see the perio...now im imagining maybe i have the symptom of difficulty in swallowing, slightly, or am i just imagining it becim thinking about it too much.....no pain really, nothing....what should i do.
