Root Canal Therapy (Endodontic Treatment)

At Southern Dental in Houston, we look for ways to save your natural teeth, even when tooth decay or infection advances to the point that it reaches the nerve or tissue inside your tooth that is known as the dental pulp. At these times, root canal therapy may be advised.

It is possible for Southern Dental dentists to offer this treatment in a relatively painless manner.

In root canal therapy, we remove the infected tissue and then decontaminate the canals before filling them with replacement material. Normally, a porcelain crown is then placed over the tooth. Technological advances have allowed root canal therapy to become more automated and completed more quickly.

When the nerve or root of a tooth is infected or injured it is necessary to have root canal therapy. The therapy consists on removing the infected or injured root, living tissue or pulp inside the tooth, nerves and clean the area to prevent bacteria and saving the tooth. A root canal can be the solution to save tooth from decay or infection and prevent the tooth from dying. This treatment is much preferred than just extracting the tooth as other problems could arise such as misalignment of the adjacent teeth or other dental treatments needed such as dental implants. Root canals are very successful and usually lasts a long time unless new infections need to be treated.

When is root canal therapy needed?

  • Tooth sensitivity
  • Severe tooth pain
  • Tenderness or swelling of the gum
  • Abscesses
  • Trauma or injury to the tooth
  • Tooth decay

How does root canal therapy work?

The root canal procedure has to be performed by a dentist or endodontist, who specializes in root canals. Once the tooth and gum are numb, an opening is drilled on top of the tooth and root canals places inside so that the pulp and tissues infected can be removed and the tooth cleaned from bacteria. If the tooth presents a degree of decay it will also be removed to save the tooth. When the tooth has been completely cleaned and repaired, the dentist will seal it with a temporary or permanent filling. Teeth that have been treated with root canal therapy need a crown in order to protect the tooth and ensure the tooth is fully functional. While the tooth heals, it will be sensitive and present some inflammation, your dentist will give you care instructions after the treatment to ensure the effectiveness of the treatment and your oral health.
