Root Canal: What it is, and Why You May Need One. The Easy Guide to Understanding Them.

When a tooth becomes infected and is decayed, then a root canal is a treatment that would be employed to repair and save it. A soft tissue called the pulp is inside the tooth, and in a hard layer called the dentin, which is under the white enamel. Helping grow the root of your tooth during development, the pulp contains nerve and connective tissue, as well as blood vessels. A tooth continues to be nourished by the tissues surrounding it, even without the pulp, because a fully developed tooth can survive without it.
After a tooth has grown through the gums, it’s nerve is not essential to the health of the tooth. Providing the sensations of hot or cold is it’s only function, which is a sensory one. The day-to-day functioning of the tooth will not be affected by the presence or absence of a nerve.

Root Canal: Reasons For It

If there is damage to the pulp or nerve tissue of a tooth, it will grow rampantly within the pulp chamber as it breaks down. The end of the roots of a tooth will from a puss-filled pocket called an abscess, or an abscessed tooth. This as well as an infection can be caused in the tooth, if there is bacteria and other decaying in it.

Situations like trauma to the face, a chip or crack in a tooth, large fillings, and/or repeated dental procedures on a tooth, or deep decay can cause a tooth’s pulp and nerve to become infected, or irritated and inflamed.
A root canal becomes necessary when a nerve has been affected.

Root Canal: What Are the Signs That One is Needed?

Even though there are sometimes no evident symptoms, below are some signs that may indicate a root canal is needed:
  • A recurring or persistent pimple on the gums
  • Tenderness and swelling in near by gums
  • Darkening or discoloration in the tooth
  • Prolonged pain or sensitivity to cold or hot temperatures (after the heat or coldness has been removed)
  • Severe toothache pain when applying pressure or chewing
Root Canal: What Happens During One?
A dentist or an endodontist (a dentist who is a specialist in the treatment of injuries and diseases of the nerve of the tooth or the human dental pulp, and there diagnosis, causes and prevention) can perform root canals, and they need one or more office visits.
Taking an x-ray to determine the condition of the canal of a root, and see if there is any surrounding bone infection, is the first step in the root canal procedure.
To numb the area near the tooth, we will use local anesthesia next, and place a rubber dam (a sheet of rubber) around the tooth to keep the area dry and free of saliva during your treatment.
To keep out contaminants such as food and saliva in between dental appointments, we place a temporary filling in the exterior hole, in case the root canal procedure is not completed on the first visit. Then it is sealed when it is completely cleaned.
A rubber compound called gutta percha and a sealer paste are placed in the root canal of the tooth in the second appointment, to fill the tooth’s interior. A filling is placed to fill the exterior hole which was created at the treatment’s beginning.
In order to protect a tooth that has extensive decay or other weakness, or has a large filling, a post and crown, or other restoration may be needed.
