Before performing root canal, your dentist might suggest you to take a series of dental x-rays to exactly locate your infected tooth. This is to get a fair picture of the root canal to assess the extent of any damage.

Root canal treatment is carried out under anesthesia which will help to numb the affected areas of tooth. If in case your tooth is dead, there is no need of further anesthesia.

Removing the pulp

In order to remove the pulp, your dentist may place a rubber dam around your tooth to keep this area dry during treatment. This rubber dam also assists in preventing you from swallowing or breathing of any chemicals that the dentist may use. Now, a hole is made through your crown to remove the infected pulp. Your dentist can also remove dental abscess (pus-filled swelling) this time, if present.

Cleaning and filling root canal

The pulp is hence removed. Subsequently, your dentist will clean and enlarge the root canal in order to fill it easily. For this, your dentist will use series of small files.

The type of root canal treatment that is apt for you is decided based on teeth type. A single root canal treatment is required for your front incisor and canine, since they have a single root. One or two root canals are required for your premolars and back molar teeth since they have two or three roots. In fact, greater the number of roots a tooth holds, the longer will be the root canal treatment.

In order to accomplish root canal treatments in different sections, your dentist will fill appropriate medications in cleaned canal between the dental visits in order to destroy any entering bacteria. The tooth is then sealed with a temporary filling. In some cases, antibiotics may be prescribed to prevent further infection.

Sealing and fixing the tooth

During the very next dental visit, your dentist will fill your teeth by removing the temporary filling and medication within the tooth. Along with this, tooth will be sealed to prevent further infection and finally, your dentist may suggest placing a crown on the tooth to protect it.


Crown is used to cover your tooth after the entire root canal procedures. This is to prevent tooth fracturing. Crown is attached to your trimmed-down tooth with cement.

After root canal treatment

The survival rate of tooth is more, when crown is fit to tooth that has undergone Root canal treatment.

However, the survival rate of your tooth depends on certain factors which are cited below:

· How much of your natural tooth remains

· How well you take care of your teeth

· The biting forces on your tooth
