A root canal refers to a kind of dental treatment that can repair or save an infected or decayed tooth. During this procedure, the pulp and nerve are removed and the tooth is cleaned inside and sealed. If left untreated, the tooth’s surrounding tissue could become infected, causing abscesses to form.
“Root canal” actually happens to be the term that describes the tooth center’s natural cavity. The soft bit inside of it is known as the pulp chamber where the tooth’s nerves lie. Although these nerves aren’t exactly vital for overall tooth function and health after the tooth comes out of the gums and although these nerves will not affect everyday tooth functions, they still have sensory functions of providing cold and hot sensations to a person.
If these tooth nerves get damaged, they break down, allowing bacteria to multiply inside the pulp chamber. Because of this, decayed debris like bacteria will get the opportunity to cause an abscessed tooth and various infections. In turn, these infections can cause swelling in various other places like the head, face, or neck; bone loss at the root; and drainage problems from the root.
So, how do these tooth nerves get damaged to begin with? Well, they can get infected, irritated, and inflamed because of deep decay, large fillings, repeated dental procedures, tooth chips or cracks, or face trauma.
Although symptoms aren’t always present, you may need a root canal if you experience extreme tooth pain upon applying pressure or chewing, prolonged pain or sensitivity to cold or hot temperatures, tooth darkening or discoloration, gum tenderness and swelling, or a recurring or persistent gum pimple.
