I need your advise. I always had gum inflammation and bleeding but around a week back a red lump suddenly appeared near a tooth that had root canal treatment and crown since around 20 years. When i press the gum pus is coming from the lump. Went to periodontist and he said a surgery is needed to open the gum for 3 teeth and it would cost around 1200 AUD. He did not want to give me antibiotics and I am trying home treatments like salt and baking soda rinse, garlic over the lump,... nothing seems to be working. There is no pain only I became obsessed with this lump and am afraid the infection will spread.What shall I do?
