Persistent Apical Periodontitis

Sometimes periodontitis just seems to not go away, regardless of how many treatments we undergo. Course after course of antibiotics and root canal treatments still yield the same results, and vigorous oral health care and maintenance still offer no solution, gums remain swollen, with possible halitosis and discharge. It is indeed a bad situation, and can cause the tissues to be extra sensitive and inflamed. 

Apical Periodontitis

The causes of apical periodontitis are to be found underneath the apex of the tooth where the gums are acting up. Usually teeth that have previously been root canaled are the ones that will develop a bacterial infection outside of the apex of the tooth Thus, when the tooth is treated and root canaled, the bacteria do not have any other place to grow, except into the gums and the alveolus of the patient, and will start to live there. This can be one of the causes for a persistent gum infection, and taking antibiotics will not kill a large deposit of bacteria near a tooth, as the bacteria can just move to the apex of the tooth, and the bacteria may survive. If the bacteria have lived in your mouth for a large enough period of time, they may also have developed a resistance to antibiotics. This way, the only way to cure a persistent, recurring case of apical periodontitis is to have that tooth removed, and the bacteria removed through oral surgery as well. 

Complex Biofilms

The other reason that a recurring case of apical periodontitis may be hard to kill is because the biofilm that the bacteria grew out of are usually made of several different kinds of bacteria, not just one. It is well possible for several different strains of bacteria to live next to each other in relative peace, a slong as there is enough sustenance and space, which the human mouth is plenty capable of providing. This is why there can be more than one kinds of bacteria living in your mouth simultaneously, and all of them may be infecting your periodontium. These cases can only be cured with oral surgery, or with a complex series of dental treatments, and is not an easy situation.
