basically its kinda my fault i had a root canal and it was completed just the tooth was to be closed but i didnt go for it and now its been around 4 years just recently i noticed a small red growth in that cavity and it bleeds at times so i would like to know if this is serious or can it wait and what is it
This is the infection . I also got the same condition and then had to remove the tooth altogether as the tooth had decayed. Go and have an emergency check up or you gonna end up in lots of pain and tooth removal.
