Only removing the bad tooth and replacing it with a bridge, implant, or partial denture is a viable option. A root canal surgery, fortunately, nearly always saves the tooth and allows it to stay in place for the rest of the patient’s life. All surgeries are successful in more than 95% of the time.
Unfortunately, despite the dentist’s best efforts, things do occasionally go awry. Remember that the tooth’s nerve and pulp will be removed throughout the surgery. The “root canal” (the hollow space inside the tooth) is then cleaned, sterilised, and sealed. Your dentist will attempt to remove all germs, poisons, and other pollutants from the tooth in addition to removing all damaged, diseased nerve tissue. The nerve’s hollow region is then filled in and sealed off, preventing germs and other irritants from occupying any physical position beyond the reach of your body’s natural defences. However, the previous infection may flare up again, or a new infection of the tooth may develop.You may find more details about this at Lifetime Family Dental – Kaysville Dentist.
This could happen for a variety of reasons:
A small fissure in the tooth’s root may have gone undetected, allowing germs and other pollutants to enter.
The shape of a root canal varies widely from patient to patient, and some configurations are more difficult to fully clean.
If the tooth has more root canals than expected (or unanticipated forks or branches of the same root canal), your dentist may have accidentally omitted cleaning one of them.
After the root canal surgery, the dental repair (a crown, for example) may fail, allowing germs to re-enter the tooth’s inner cavity (we discuss this process, known as “coronal leakage,” in more depth in a separate article); and
The root canal sealant utilised during the treatment may erode and fail over time, letting germs to infect the root canal once more.
If the treated tooth harbours germs or pollutants that induce inflammation of the tissues surrounding the root of the tooth, the procedure is deemed a failure. Even if dental X-rays show indicators of inflammation, root canal problems might occur without causing any symptoms. In other circumstances, the patient may have tooth discomfort, edoema, or tenderness of the gums.
