An Overview of Root Canal Treatment
Sometimes a tooth is so severely damaged that the only way to save it is with root canal treatment. There is no reason to turn and run if your dentist advises this procedure. The treatment has advanced to the point that it’s often compared to getting a filling. There are certain steps that will be performed as part of nearly every root canal procedure.
X-rays may be taken as part of the diagnosis process or to determine the extent of damage. Once the dentist is ready to begin treatment, a local anesthetic will be used to numb the area throughout the procedure.
A rubber dam will be placed around the tooth to separate the area from the rest of the mouth, and to keep it dry from saliva. The tooth will be opened, often using a small dental drill, to gain access to the pulp inside the tooth. The damaged pulp will be removed, and if there is an abscess it will be drained.
Cleaning and filling
After the pulp is eliminated, the dentist will thoroughly clean the area. The root canal will be widened if needed to create an adequate space for the filling. Depending on the extent of the damage, this step of the process can take up to several hours to complete or it can be spread over more than one visit. A temporary filling is sometimes used to seal the area between visits. If infection is present, the dentist may prescribe antibiotics.
The temporary filling will be removed and the permanent filling placed to fully seal the tooth and prevent future infection. If the tooth has been filled at the root, the risk of breaking is higher so a crown may be recommended for protection.
Crowns help prevent further damage or fracturing. If needed, the tooth will be reduced somewhat to allow space for the crown. It will be held in place securely with dental cement.
After root canal treatment, the tooth should survive for many years. The procedure may be repeated if re-infection occurs.
