When Root Canal Retreatment Happens

Even tough most of the root canal procedures are successful the first time around. There are many reasons for a root canal retreatment to be needed, such as bacteria re-infecting the tooth. Fillings might also leak or break. Sometimes the dentist failed to locate and inject fillings in all of the canals. All of which causes bacteria to grow back in the affected teeth and cause pain and root canal infection.

A consecutive root canal treatment tends to be more invasive and take longer than the first one. The professional has to remove the crown, post and all the filling from the first time. Only then he can do the second root canal.

Sometimes the tooth is to fragile for a second root canal. The post might be set in too tightly for a removal. In that case the tooth might fracture in the procedure. So your dentist might opt for a endodontic surgery instead. This allows the dentist to, instead of opening the crown, access the root from the bottom of the tooth.

Root Canal Retreatment: Procedure

Endodontic procedures happen at your dentist’s office and can be performed by endodentists, general dentists or oral surgeons. Your dentist will start by applying anesthetic to the area. Then he will cut a little portion of the gum near the base of the tooth. After that the infected tissue around the tip of the root will be cut clean and the tip trimmed so the root can be reached. The professional will then remove the remaining infection inside the canal and then put in the filling just like a root canal retreatment would, but from the bottom of the tooth. Then the incision is stitched.

Endodontic surgery is successful 85% of the time. If it happens to fail the tooth will have to be removed.
