Root canal treatment or endodontic treatment is necessary when the center part within the tooth, known as the pulp, involving the blood vessels, nerves and living connective tissues, become infected or inflamed.
The root canal procedure is performed to save a damaged or poorly infected tooth, rather than uprooting it. This procedure is performed by an endodontist or a root canal specialist.
The most common causes of tooth damage or infection are, cavity due to plaque accumulation, cracked or broken tooth due to any accidents or trauma, and repeated dental treatment to a particular tooth. These issues can cause pulp inflammation, and infection and irreversible damage to the pulp. The patient may at times experience excruciating pain. The pain may subside when the pulp dies, but may frequently return as the infection spreads.
It's judicious to see a general dentist incontinently if you experience a toothache.
The entire root canal procedure may take place in one sitting, or at times 2 or 3 sessions depending on the condition of the tooth. Each sitting may last between 30-90 minutes. It's a simple procedure with fairly little or no discomfort.
