What is a Root Canal
What is a root canal?
A ‘root canal’ is an endodontic treatment that removes only the diseased and infected part of a tooth, instead of removing the entire tooth. Your tooth is made up of three layers. The white visible layer is called enamel, underneath is called dentin, and lastly, in the middle is a soft tissue called the pulp. The pulp is made up of blood vessels and nerves and helps the tooth to grow at the development stage in life. However, once the tooth is fully grown the pulp is no longer required because the tooth can get its nourishment from the surrounding tissues.
Sometimes the pulp can get infected by bacteria which results in it getting inflamed. This infected pulp is removed in a root canal. The interior of the tooth is then treated to prevent further infection and then filled and sealed, to preserve your tooth and protect your smile.
When do I need a root canal?
A root canal could be required due to a cracked tooth, genetic reasons, issues arising from previous fillings, or because of a deep cavity. The primary symptom of needing a root canal is when you notice your teeth are particularly sensitive to hot and cold. Other factors that you might need to keep in mind include:
Decomposition or blackening of the gums
Swelling or tenderness in the gums
Pain or discomfort of the tooth when chewing
A pimple-like swelling on the gum
Does a root canal hurt?
Contrary to what you have heard, because a root canal is done under local anesthesia, it is actually no different than any other dental procedure such as filling or removing a wisdom tooth. In fact, usually, a root canal is to treat and relieve the sharp pain from a toothache caused by the infected pulp.
There could however be a bit of numbness and soreness for a few days after the root canal, which could cause some mild discomfort, and the tooth the procedure was done on might feel a little different from your other teeth for some time. If you feel severe pain or pressure after your root canal, you should contact your dentist for re-evaluation.
How long does a root canal take?
A root canal is a relatively simple procedure and can be probably completed in one to two appointments. During the appointment, the infected pulp is removed and the root canal is cleaned and disinfected. After a period of rest, in the second appointment, the root canal is cleaned and disinfected and a filling is placed to prevent future infections. Each appointment can take up to approximately 30-90 minutes.
