Issues Related to Root Canal Treatment
Root canal networks within teeth are highly complex. They exist rather like the branches of a tree. The narrowest branches may be impossible to instrument. Therefore, even after a successful root canal treatment, some nerve tissue may remain. Also, it may not be possible to eliminate all bacteria present – particularly if infection has leached out beyond the root tips. Therefore, even with the most accomplished root canal work possible, a successful outcome cannot be guaranteed. In certain cases the root canals may be completely closed-up and are impossible to instrument. In these cases, root canal treatment may not be possible.
Retreatment of teeth that have already had root canal treatment can be complicated by many reasons, which your dentist will discuss with you on an individual basis. There is a risk that infection may develop following root canal treatment. Such infection can occur shortly after (or during) a course of root treatment or in the more distant future. Generally, in the event of infection developing the tooth would require extraction. Root treated teeth are usually already heavily filled or badly decayed. After tooth tissue has been
removed during the root treatment, relatively little of the tooth remains. Consequently, root treated teeth are highly brittle and there is always a risk that they will fracture. A crown similar restoration is required following root canal treatment.
Despite these considerations, root canal treatment may be selected as the treatment of choice. Your dentist may recommend referral to a specialist, which would involve additional cost.
