The inflammation of the apex of the dental root lasts for a long time and expands to the adjacent bones long before it becomes apparent due to the accompanying pain. As a rule the problem is restricted to the teeth whose nerves have already died, or those that just had their canals filled.

We also perform a protective resection of the dental root while trying to save the teeth the root canals of which cannot be optimally cleaned or filled with the regular root-canal treatment on account of strong curving or the constriction of the canal, as well as those which regardless of repeated root canal cleaning still cause pain.
'The condition for the successful treatment is first of all that despite the inflammation of the root area the tooth remains strongly attached to the sufficient amount of the bone.

The inflamed root apex is seized through the possibly smallest, gum-sparing cut, and the surrounding inflamed tissue is carefully removed.

If the root of the tooth has not yet been filled at another location, we fill it during one visit.

If the root of the tooth has been filled, we make the filling tighter again, just in case, at the cut-off root apex (so called retrograde root-canal filling).

It is imperative for a long-lasting success that the bacteria that have caused the inflammation are possibly entirely removed and the cleaned area of the root apex heals unaggravated in the months that follow the operation.

Through an additional application of the laser (photodynamic laser therapy, private payment) we succeed in the almost 100% removal of the bacteria that cause the inflammation.
