You might feel anxious and scared to take your first root canal treatment. This is because you are not familiar with the dental procedures and might have heard about its misconception. Do you know that in rare cases, root canal treatment might be the only option to consider to avoid the loss of a tooth. Saving your natural teeth is the best thing and nothing artificial can look or function the same. But you need to know what the treatment is and what the root canal treatment side effects are.

What is a root canal treatment?

Root canal treatment is nothing but removing the top part of the tooth which is called the crown, and the part that is below the gum is the roots. Your entire tooth is made of roots and it’s responsible for holding it in place with the help of bone and tissues.

Your natural tooth structure has a chamber in the middle of the crown and the root canals. When your tooth gets infected, it causes pain and the decay will get deep. In this situation, you might need a root canal treatment. This is also known as endodontic treatment.

The treatment involves cleaning the canals to remove bacteria and the pulp. The treatment aims to prevent reinfection and it is usually done by a dentist or an endodontist and the treatment might include one or two appointments.
