Dental abscesses often occur as a pronounced swelling in the gums at the root level of deep decayed teeth or teeth with failed root canal treatment. When the factors causing abscess are eliminated, dental abscesses heal in a very short time. What is important is that an experienced physician can accurately determine the source of the abscess.
Teeth with root tip abscess can also damage surrounding anatomical tissues. Especially in many people with sinus infections (sinusitis), the source of infection can be mostly inflammed teeth.
As dental abscesses grow, they cause bone loss as they grow by melting the bone around them, and as a result of these losses, neighboring teeth may also be damaged.
