Root canal is usually painful
Most people fear that a root canal treatment is usually associated with pain during treatment. Your dentist or endodontist will give a local anesthesia to numb the area around the tooth. If you are very apprehensive and tense you may need sedation, such as nitrous oxide. This eliminates the pain that is caused due to the procedure. If you have pain while the procedure is being done, tell your dentist about it. Your dentist will adjust the technique to avoid causing pain again or give more anesthesia if required.
As my tooth's nerves are removed, I won't feel any pain
Some people think that after the root canal treatment they won’t feel any pain in the treated tooth. However this is not true. Even though the pulp of the tooth is removed the nerves that surround your tooth can feel pressure and touch. These sensations are transmitted by the nerves in the surrounding tissue. In addition after the procedure you can have soreness in the concerned tooth for two to three days. You may be prescribed pain relievers such as acetaminophen or ibuprofen to ease the discomfort.
Why should I get a root canal treatment if the tooth may have to be taken out eventually?
A tooth after root canal treatment can last for the rest of your life with proper care. To increase the longevity of your teeth maintain good oral hygiene. To maintain healthy teeth and gums brush with fluoride toothpaste (twice a day) and floss everyday. Go for regular dental checkups and professional cleanings. Root canal treatment has helped to save several teeth that would or else need extraction.
If I don’t have any pain, I don't really need a root canal
It is very much possible that your tooth that needs root canal therapy may not have pain. But remember that absence of pain does not mean that your tooth is healthy. Like an infection of the pulp of the tooth may not cause pain initially. But without treatment it can cause pain and swelling. In some cases untreated infection can cause pus accumulation at the root tip in the jawbone, forming an abscess. Untreated abscess can extend and destroy the bone around the tooth and cause pain. After examination if your dentist recommends root canal treatment get it done even if there are no symptoms.
In root canal therapy the roots of my tooth are removed, or my whole tooth is removed
A tooth has outer enamel, the dentin (main body of the tooth) and soft tooth pulp (in the center of the tooth and in canals also called root canals). Nerves and blood vessels enter the tooth through the end of the root (called the apex) and then pass through a canal inside the root to the pulp chamber. In root canal treatment, the tooth pulp which may be inflamed or infected is removed. After removing the diseased pulp tissue, the space is cleaned, shaped and filled. In root canal therapy the roots of the tooth or the whole tooth is not removed.
After root canal, I don’t need to go back to the dentist for a while
After root canal therapy, you might think that you don’t have to go the dentist for a sometime. But it is important to go for follow-up and have the permanent restoration placed. If the crown is not placed on the back teeth, the risk of fracturing the tooth when you bite down or chew is higher.
