Inside your tooth, there is soft, living tissue that contains blood vessels and nerves. This tissue is called the pulp. When the pulp is injured or diseased and cannot repair itself, it dies. Common causes of pulp injury or disease include a cracked tooth, deep cavity, problems with a large filling, or injury to the tooth. In the past, in cases like these, the dentist would usually pull the tooth. Luckily, we are now able to save the tooth with a root canal.
A root canal treatment takes one or more dental visits. First, I will numb your tooth. Then I will make an opening through the top of the tooth into the pulp chamber. The injured pulp is removed, and the root canals are cleaned and shaped. Next, the root canal is filled with a rubber-like material. Finally, the tooth is restored with a filling or a crown so it is stronger and looks nicer.
A tooth with a root canal filling can last several years. However, like your other teeth, daily cleaning and regular dental visits can keep your teeth healthy.
