If an infection has occurred at the tip of the root of one of your teeth often it does not cause any symptoms but usually people are aware of discomfort and occasional episodes of swelling, gum boils or bad taste. You may well already have been given a course of antibiotics in an attempt to treat the infection.
If left untreated the infection is likely to develop into an abscess or cyst. As well as causing pain this can lead to the loss of bone surrounding the root. As a result, the tooth will become loose.
Your dentist will have already tried to get rid of the infection by removing the nerve of the tooth and placing a root filling. The infection now needs to be removed surgically in a procedure called an “apicectomy”. This involves cleaning out the infection from the bone, removing a small portion of the tip of the root of the tooth and then sealing the root with a small filling.
It is necessary to make a small cut in the gum over the root of the tooth and then lift the gum off the bone. The area of infection is uncovered by removing a small amount of bone with a drill. Any infected tissue is thoroughly cleaned away from the tip of the root before 2-3mm of the root tip are removed. The root is sealed with a small filling. The gum is then stitched back into place with dissolvable stitches that take around two weeks to disappear. The whole procedure will take around 30 minutes from start to finish.
