A root canal may be needed if the decay has reached the tooth’s nerve.
Essentially, a root canal involves cleaning out a tooth’s infected root, then filling and sealing the canal.
1) An opening is made through the crown of the tooth into the pulp chamber.
2) The pulp is removed, and the root canals are cleaned, enlarged and shaped.
3) The infected area is medicated.
4) The root canals are filled.
5) The crown opening is filled with a temporary filling.
Causes for a Root Canal
A cavity that has been left untreated can become larger. And once the cavity reaches the pulp of the tooth, an infection forms at the base of the root canal, causing an abscess. This abscess is generally painful and will need to be removed.
When Is Root Canal Necessary?
If you noticed that your tooth becomes sensitive to drinks or foods, you may be suffering from a dental problem. The pain may be intense. If the pain goes away quickly, probably you are experiencing a minor dental problem just like tooth cavity. However, if the pain did linger for a longer time, you are probably experiencing from tissue damage due to infections in the pulp. In this condition, root canal may be necessary.
The Signs When Root Canal Is Needed
– Tooth discoloration
– Tenderness or swelling of gums around the tooth
– Pimples on surrounding gums
– Pain or extreme sensitivity to food and drinks
– Severe toothache when biting or chewing
